Removal Of Vertebral Column And Dorsal Root Ganglia

How Many Cats Do You Have?!

In both Canada and the USA : to ensure complete removal of the dorsal root ganglia, the vertebral column of cattle 30 MOA or older excluding the vertebrae of the tail, the transverse processes of the thoracic and lumbar vertebrae and the wings of the sacrum must be removed and disposed of as inedible product vertebral column removal will most likely be done in the same plant, in the fabrication room slaughter establishments that do not remove the SRM vertebral column on-site must implement an identification system and shipping controls satisfactory to the veterinarian-in-charge controls should include notification of the inspector-in-charge of the receiving establishment and the number of carcasses/sides/quarters to be expected and receiving establishments must have a verifiable control system in place to demonstrate that all parts of the vertebral column are removed and appropriately disposed of.

Frederick et al. said removal of the dorsal root ganglia is difficult to fully control visually and suggested that if the meat is cut out in U-shaped fashion between individual ribs or vertebrae, and if the cut is not too deep into the inner area of the arches, inclusion of dorsal root ganglia in wholesale cuts or beef trimmings can be prevented.

Cat Leg Bones Hind Limbs

So, lets move on to cat leg bones.

As we all know, cats have powerful hind legs, helping them climb and leap long distances to catch prey.

To work with their powerful hind leg muscles, cat leg bones are strong and flexible. They support this wide range of movement and, compared to our own legs, their layout may surprise you.

For a start, the bone we think of as our thigh bone is right up in their haunches.

And, the bones at the top of their leg at the top of their leg are the tibia and fibula, bones that we think of as our shin bones.

So, whats in their shins, I hear you ask?!

Cats actually have a metatarsus, which is a long foot bone just like the ones we can feel through the top of our feet! This configuration is beautifully adapted for propelling our cats high and far when they need to leap.

Leaping is one thing, but what about landing? Cat forepaws are perfectly designed to absorb the shock when they land. Of course, they also give cats agility and speed when hunting and fighting.

Anatomy Of A Cat Skull

The small skull of the cat is attached to the vertebral column as is the case with other mammals, and it contains air filled sockets also known as sinuses. There are two sinuses within a cats skull the frontal sinus and the maxillary sinus. The eyes socket within the skull, are large enough to contain the huge eyes of a cat. Also located in the skull of a cat are its teeth. A normal adult cat has 30 teeth. The cat isnt your average carnivores as it comes built with 12 incisors, 4 canine, 4 molars and 10 premolars all made perfect for devouring flesh.

Why Do Cats Have Bones

Okay, this sounds like a silly question, but we want to give a final shout out to all the amazing things our cats bones do besides hold them up, keep them balanced, and protect their internal organs.

First, the marrow inside cat bones makes red blood cells and some white blood cells. This is important for keeping your cat healthy, making sure that oxygen goes where it needs and protecting kitty against infection.

And second, cats use their bones to store fat, and even some minerals such as calcium and phosphorous.

Put simply, a cat skeleton is a finely engineered, multi-tasking marvel! Who would have known all of these fascinating cat skeleton facts just from looking at a cat skeleton picture? The cats skeleton structure is what makes them supreme hunters, giving them all the tools they need to survive.

So, when you look at your plump moggy playing with her toys, stop to think about the marvellous cat bone structure that lets her do this.

Anatomy Of A Cat The Brain Of A Cat

How Many Vertebrae Do Cats Have In Total

The brain of a cat occupies about 0.9 percent of its body mass, and does the job of interpreting inputs gotten from the senses.

Cats are known to have 300 million neurons and a lot of nerve cells in the visual area of their brain.

When compared to dogs and most mammals, cats have a more complex and advanced brain. Their brain comes equipped with a complex cerebral cortex, this makes the average cat far more intelligent than a dog.

As a result of this feature of their brain, the tendency for aged cats to develop a medical condition quite similar to Alzheimers disease in humans is very high.

Abnormalities may be apparent from birth otherwise, signs appear over weeks to months as the cat develops and grows . Usually these problems are untreatable and if severe the animal is likely to become ill and die of complications unless euthanased. Life expectancy is severely reduced in affected individuals. Less severely affected individuals may cope in a protected environment with close attention from their owners. Occasionally surgical treatment may help.

Why Do Cats Have Longer Backbones Than Us

Weve all seen cats twist and turn in mid fall, before landing gently on their feet. Did you know that cats use their extra long spines to achieve this, one of their most impressive and best-known skills.

Your cats ability to land on their feet is governed by something called the righting reflex. This is a precise sequence of mid-air twists and turns they perform in mid-air to make sure they are the right way up before they reach the ground.

Without their extra vertebrae, their spine wouldnt be flexible enough to make these twists as quickly as they need. Without such a flexible spine, their reputation for landing on their feet might not exist.

If you are interested , you can read all about how cats right themselves in mid-air and the role of their backbone in our article Do Cats Always Land On Their Feet?

Of course, while the spine lets cats twist in mid air, and absorbs some of the shock when they land, their legs are crucial. As we will see, their legs are also powerful, giving the ability to leap and catch prey.

Much of this strength is because of the cat leg bone structure. Well look at this, next.

A Cat’s Appendicular Skeleton

The skeleton of each thoracic limb has 31 bones: the clavicles and the scapula by the shoulder the humerus is the upper arm bone, while the bones in the forearm are the radius and the ulna. Seven bones form the carpus : the scaphoid, the capitate, the pisiform, the trapezoid, the trapezium and the hamate. The front of the paw has five metacarpus bones and fourteen phalanges.

The skeleton of each pelvic limb has 29 bones: the coccyx which extends from the hips, the femur which makes up the thigh, the patella and the fibia and tibula which make up the leg. There are seven tarsal bones: the talus, the calcaneus, the navicular, the medial cuneiform, the intermediate cuneiform, the lateral cuneiform and the cuboid.

Anatomy Of A Cat Skeletal System

How many cats is too many?

Cats are built with a skeleton thats almost similar to that of humans.

Although a veterinary anatomy coloring book is ideal for vets in school working towards a degree, any feline lover can enjoy this type of an activity tool. A coloring book of feline anatomy is also a good way to learn all about the different body parts.

The skeleton of a cat is made up of 244 bones to include clavicles , but unlike that of humans, the collar bones arent connected to other bones.

The exterior of each of its bone is made up of protein and minerals that help give the bone its firmness its interior on the other hand, contain a marrow cavity responsible for producing red blood cells.

There are lots of magical pieces making up this unique physique.

Here is a list of the different feline body parts taken from wikipedia that reference a diagram you can view on their site here.

Cat Leg Bones Fore Limbs

Even though we think of cats as having four legs, when we talk about cat skeleton anatomy, we give the bones in their front legs the same names as the bones in our arms.

Just as another interesting little fact, cats are much less likely to break the bones in their forelimbs than in their hind legs.

Approximately three quarters of long bone fractures seen by vets are in the femur or tibia.

In contrast, fractures of the long bones in the fore legs only account for about 16% of long bone fractures.

The strength of cat forelimbs is partly due to the strong bone structure. However, part of it is because cats have inbuilt shock absorbers.

Thats why, perhaps the most interesting thing about our cats front legs is how they attach at the shoulders

Do Cats’ Tails Grow As They Age

A cat’s tail does grow as the cat ages. However, after the cat is full grown, the tail remains the same size. Cats can keep growing up to 2 years of age, which means their tail can continue to grow with them. However, cats are born with the number of vertebrae they need, so the tail growing has more to do with anatomical development rather than growing more bones.

    Its A Communication Aid Too

    Cats communicate largely through body language, and the cat tail is one of the most important parts of your cats communication toolbox. By understanding tail talk, you can understand how your cat is feeling with just a glance.

    A happy cat, for instance, walks with her tail held high, and a super-happy cat will add a quiver at the tail tip to demonstrate her joy. A mildly annoyed cat will twitch the end of her tail, but if shes lashing her tail back and forth, youd better step away, because the claws are about to come out. A cat concentrating on prey will have her tail held low to the ground, although there might be a very slight twitching at the end as she tries to control her excitement.

    What Are Cat Bones Made Out Of

    Bones are effectively made of two major components collagen and calcium phosphate. Vitamin D and some other minerals and vitamins are in charge of storing calcium in the cats bones. While rickets is a condition a lot less common in cats than in dogs, it can still affect them if they do not get the right nutrition.

    In times of need, bones can release calcium in the bloodstream if it is necessary there and the cat doesnt get it from his or her diet.

    While its location and amount depends largely on the shape and size of the bone, bone marrow is pretty much present in almost all bones the flat ones have less, but they still have a good amount of vascularization on their surface and on their interior, so that they are nourished.

    Bone marrow is in charge of producing red cells and platelets, meaning a type of white blood cells. Bone marrow also contains stem cells, which are essential in some types of infection.

    Common cat bone health problems and how to prevent them

    Some of the most common bone pathologies that cats can suffer from are the following:

    • Fractures
    • Polydactyly
    • Osteodystrophy

    Fractures and bone infections are connected to each other as open fractures are extremely dangerous from an infectious standpoint. More often than not, they become complicated with bacteria. Bone infections are very challenging to treat.

    As previously mentioned, rickets appears as a result of a lack of vitamin D in the cats diet.

    Cat with Pelvic Fracture, surgery is not affordable

    While a tail is very useful to a cat, cats without tails learn to adapt easily to a tailless life. Cats without a tail are not restricted in any way. Even cats who have a tail and lose it due to injury learn to adapt quickly to life without a tail.

    Tails have evolved in many different groups of animals and serve important purposes. Cats are one of the many animals that have benefited from having a tail. Tails are filled with bones, nerves, blood, muscles, and scent glands. All of these anatomical features work together to provide cats the ability to balance, navigate quickly and efficiently, and communicate with the world around them. The way a cat holds their tail can tell you a lot about its intentions and mood. Cat owners should quickly learn the nuances of cat communication as this will set you and your cat up for success.

    What Is A Cats Tail Made Of

    The bones in a cats tail are known as caudal vertebrae. Cats typically have 18-23 caudal vertebrae . Cats with no tails, such as the Manx cats, or cats with shorter tails, will have fewer caudal vertebrae. Even humans, who do not have a tail, have 3-5 caudal vertebrae. Our caudal vertebrae are fused together and form one bone, the coccyx, which helps stabilize us when we sit. Other ape species, like gorillas and chimpanzees have this bone as well.

    Other vertebrae help the tail to function. Cats have the same number of cervical vertebrae as most other mammals, but they have an additional vertebra in the thoracic region and two more vertebras in the lumbar region than humans. The extra vertebrae give cats increased flexibility in their spine and helps them with their speed and agility. The tail is a crucial part of these skills.

    Nerves run throughout a cats tail, which helps them pick up information from the environment around them, essentially allowing them to feel with their tail. The tail is part of a cats spinal cord and contains nerves from both the central and sympathetic nervous system. Nerves send signals throughout the body to help the body coordinate a response to the environment. These nerves send information from a cats tail all the way up to its brain, allowing the cat to respond to whatever is happening around them in a split second.

    A cats tail also contains scent glands, called caudal glands. These aid cats in scent marking their territory .

    Which Are The True Ribs

    The ribs are a type of bone that is found in the thoracic region. They can be located on either side of the chest and provide protection to the heart, lungs, and other internal organs. There are 12 different types of rib structures that can occur in humans including true ribs, false ribs, floating ribs, vertebral ribs, sternal ribs and costal cartilages. The term “true” refers to those bones which have a direct attachment to either breastbone or spine while “false” refers to those which do not have this connection. In this blog post we will explore some interesting facts about these important bones.

    Some Manx cats appear normal, apart from their short tails, and show no signs of spinal cord dysfunction. Others have major abnormalities of the spine and spinal cord as outlined above which result in lack of proper functioning of the hind limbs and urinary and faecal incontinence. These individuals may be regularly soiled in urine and/or faeces which cause skin inflammation, irritation and infection and which requires constant nursing care. Affected individuals are unable to move freely which affects their ability to behave normally. Spina bifida does not cause pain unless there is spinal cord infection. Stumpy cats are prone to painful arthritis in their abnormal tail stumps.

    Severely affected individuals cannot lead normal lives and are usually euthanased at an early age. Individuals with spina bifida aperta may get spinal cord infections leading to a rapid severe illness often causing pain and death.

    It must be remembered that the unique appearance of the Manx actually constitutes the relatively normal end of a spectrum of genetically controlled characteristics that include serious and potentially lethal abnormalities .
