#cat dissection

throwback to cat dissection in highschool anatomy!!

[thelifeofavettech]

Lab today was pretty fun. We’re still working on dissecting our cats, and today we had to look at the urinary system and the ear.  And since we were working on the head, our teacher said she’d give us extra credit if we could get into the brain. So we cut off the head and spent a lot of time basically mutilating it to get to the brain. We actually had a ton of fun doing it and got the brain out pretty well, though we pretty much destroyed the cerebellum. It was cool to see the different surfaces and bones inside the head and how things fit together.

introduction: 

dissection is an act of cutting into a body (usually/hopefully a corpse) human or nonhuman for the purpose of studying or analyzing it. comparative anatomy is the study of similarities and differences in the anatomy of different species. comparative anatomy has long serves as evidence for evolution, it indicates that various organisms share a common ancestor. cats are used for dissection because they have a large body so the insides are seen better and the cats’ structure are very similar to a human's body.

purpose:

the observation of the external features that the cat, named Akito, has.

method:

the students picked a number from a bucket since the number corresponds to a cat and a bin. put cat on the lid of the box and checked if there are enough tools in the toolbox. grabbed the scissors and cut the sealed part of the bag. slowly removed the cat from the plastic bag, while keeping all of the liquids in the same bag. in the end, everyone took photographs of their cats and their different regions. to see the cat's mouth, the students used tweezers to open the cat's mouth. to see close, use sissors to cut a piece of skin from the lower/hind legs and neck. receive a glass slide and microscope. turn on the microscope and put one of the skin pieces on the glass slide, and place the slide on the microscope. use the 4x knob and take a picture of the skin. repeat with the other skin piece of skin that’s from the neck region (thick skin).

discussion/analysis:

the original claim was supported by/from the data. all the data, or information, and pictures shows what was seen on the cat. the cat’s anatomy is very similar to a humans’ anatomy. the differences are the different placement of the teeth within humans and cats, the placement of ears, humans have hands, cats have paws, cats have whiskers and humans don’t, and the mammary glands are in different places. cats have mammary glands along their body and humans have it in their upper body.

results akito is female. She had a slit throat strands of hair all over her body, and is skinned. she had a lot of fat around her thoracic and pelvic region. she also had a bright-blue vein on her right arm and a red vein on her left arm. she had cloudy eyes, which means she was blind, and a slight locked jaw. akito had two forelimbs and two hind limbs, a tail, a face, whiskers, vibrissae, paws, ears, teeth, and pads. in the mouth, akido had four canines, eleven incisors, four molars, and eight premolars.

questions (well answers actually):

the cat, akito, had a lot of fur on her head. she had these blue eyes but not well seen since they were cloudy which means she is blind. knowing that she is blind, means she had to feel what was going around her. every cat has a rough tongue which is used to clean fur off themselves and their spawn.

the thick pads (or the toe beans) are used for balance while the cats are walking. the pads allow her to move around without falling because they create friction to the ground and on steep areas.

the air or wind carry vibrations. the cats’ whiskers can help the cats detect their paths while walking, danger, and etc.

cats’ and humans’ dental structures are very similar to each other but the difference is that the felines’ dentition is much more far apart than a human’s and some of the teeth are sharper than humans’.

akito is a female. her legs are farther apart than other cats and smooth anal region which means no male reproductive system. 

conclusion:

the external features of the cat was observed on a surface and microscopic level. the students first had to look at the different regions of their cat. pictures were taken of the different parts of the cat. the students observed the different parts of the cat's face. they looked at and in their cat's mouth. in the mouth, the students figured out the different type of teeth and looked the tongue that was sticking out. the students also looked at their cat's eye, where they saw the three eyelids. the cat's gender was seen around the anal region. they concluded that the cats have whiskers for balance, cat’s tongue is used to groom herself, cats have similar dental structure but some things are different, and akito was a female since she had a smooth anal region. akito is a fat and blind cat. really dead too. the anatomy of a cat is very similar to human’s anatomy. that’s it.

Today is my first anatomy lab! I'm very excited. I'm also here super early whoops.

Warning for animal dissection and death So my day sucked, I had Comparative Vertebrate Anatomy lab today and its a class/lab I usually enjoy. But today we where dissecting frogs and cats. I've made a point of avoiding taking classes where I knew that I would have to dissect cats. I've had too many cats in my life to be comfortable with it. But that's what we where doing today and I was going to have to deal with it. But everything went wrong, I picked a random cat from the 4 that where available and took it over to a group mate at the sink to get it out of the bag and wash it. And when removing it from the bag we realized it was bending wrong and had a soft stomach, which is not typical of preserved animals. So we called the professor over and he agreed it wasn't right and its back had been broken. He told us to go ahead with the dissection but to be careful because it might not have been persevered correctly. So we start skinning it and everyone who isn't are group that quickly grew use to the gradually building smell tells us it smells really, really bad. The professor tells us if we want we can dispose of it and look at another group's but we where curios at this point as to what had happened to the poor girl. We ended up only skinning the rib cage and front legs as we where too afraid/nervous of the abdominal cavity. But her muscles where not right either, they kind of moved/slid in a weird way and felt like they had bubbles in them. Her ribs also compressed too much and may have possibly been broken By this point a much worse smell was randomly leaking out and we decided there was no chance that we where cutting in to the abdominal cavity or spine to see what had happened. So we had to dispose of her. So this poor cat had had a sucky/horrible life possibly judging by by some of the problems her body had and then we couldn't even give her a proper dissection so something would come of her death. Also she looked like my sister's cat Star who died after being hit by a car. So I felt horrible, guilty, and like puking most of the day.

today began my journey of dissecting a cat for anatomy and physiology. his name is gary, and he is a runty ginger cat. i accidentally sliced through gary's pectoralis major today. sorry gary
