The cat anatomy is very interesting. A cat's spine has many vertebra. This helps a cat turn to lick the base of its tail or even land on all four of its paws. When a cat falls, it twists around in midair so that its paws are all pointing downward. Now, the cat arches its back. This helps it parachute down to the ground. While the cat can still get badly injured when they fall, the wounds are almost never fatal. Sometimes, the longer the fall the better. When a fall is from the highest window of a 50 story building, the cat has a harder fall then if it fell from the top of a 70 story building. This is because the cat has more time to parachute to the ground.
Cats have a wonderful sense of smell. In fact, cats have twice as many smell-sensitive cells in their noses as humans do. This is a great advantage for them when they are hunting. Cats can tell if the animal they're hunting is a mouse or a vole just by its scent. Cats have an organ called Jacobson's organ that helps them smell and taste.
Cats also are grate at hearing. A cat's ear can hear even the slightest sound like the heart of a mouse pumping. A cat's ears are positioned on the top of its head. They are large and have many musculus inside of them. These musculus rotate the ear to funnel in sounds from any direction. The shape of a cat's ear helps in the process. The sound waves that the ear catches then passes down the ear canal. The ear canal is like a tube that starts at the ear and end at the eardrum. Then, in the middle ear, three bones called the ossicles transfer the vibrations from the eardrum to the inner ear, or cochlea, and auditory nerve. A cat's cochlea is located deeper inside of the head. It is snail-shaped and small. Then the sound waves are sent to the brain. This is how a cat hears.
A cat's eyesight is amazing. Cats can see in one sixth of the light that humans need to see in. Cats also have more rods (things in cat and human eyes that help them see in the darkness) than cones (things in the eyes of both cats and people too that help them see in light). Cat's eyes also have a wider angle of vision than people.
A clear cornea covers a cat's fluid-filled chamber called the anterior chamber. Behind the anterior chamber is the three-part uvea. This includes the iris, a lens, flanked by the ciliary bodies. Behind the lens is another fluid-filled chamber lager than the anterior chamber called the posterior chamber. The retina lines th
e back of the posterior chamber. The retina "reads" the light and passes this information to the optic nerve. The optic nerve then sends the information to the cat's brain which than flips the upside down image so that it is right side up.So, that is a bit about the anatomy of a cat. I hope that, for many years to come, people continue to love and care for these fantastic felines.
