COW EYE DISSECTION

Please check the outside of the eyes. You should be able to find the sclera or the white of the eye. This tough outer layer of eyes is covered with fat and muscle

2. Find the corneal covering in front of you. When the cow is alive, the cornea is clear. With your bull's eyes, the cornea may be muddy or blue

Cut fat and muscle. It is necessary only if fat is covering the cornea and it is in the way. You can leave the fat behind your eyes as it is. Flip your eyes and find the optic nerve that comes out behind your eyes. Like a rope, it is stronger than the surrounding fat tissue.

4. Cut the cornea with a scalpel or scissors. Since the cornea is harder than it looks, there are cases in which some strength is required to pierce it, so be careful when using a scalpel. When the cornea breaks, transparent liquid leaks (or squirts) - this liquid is aqueous

Please use a scalpel or scissors to make a scleral incision so that you can cut the outside of your eyes. Your goal is to divide your eyes in the first half and the second half.

The gelatinous liquid in the middle of the eye is a vitreous humor and also contains a hard spherical lens.

8. The figure below shows how to display each part of the eye after separation. Take a picture of yourself and share it on social media. # coweye (optional)

There are two layers behind the eyes. Very thin cell layer, it is easily scraped off (and sometimes it falls on its own). That is the retina. On the back, the retina is a blue reflective layer called tapetum.

The retina concentrates on the eyes that it is connected to the optic nerve. This is a CD. Probably the easiest is finding it by scraping the retina and finding where it is adhering. When the eyes are reversed, the state that the spot is directly in front of the optic nerve is also displayed.

Bullseye's anatomy is very popular due to its similarity with human eyes. Look at features such as cornea, iris, pupil, connecting muscles and veins. This is an ordinary specimen of an adult bull's eye. 10+ Prices are based on bulk samples. If necessary, we will send a combination of samples of 10 pieces and individual packaging according to your order.

The eyes of a bull are very similar to human eyes. By examining and examining the anatomical structure of the preserved bull's eyes in detail, you can see how your eyes form a world image and send it to your brain I will. This anatomical guide is perfect for high school laboratories, or you can use photos to see what is in your eyes. Please look closely at the eyes of preserved bulls. The most visible part of the eye is the large amount of gray tissue surrounding the back of the eyes (behind) and adhering to the sclera. The second visible part of the eye is the cornea, which is in the front (front) part of the eye. The cornea is cloudy and blue-gray as the eyes are held. It may also be wrinkled, and it looks a bit "squeaky". The fat and muscle tissue on the back of the eyes has distinctly rounded projections that are harder than the surrounding tissue

Place the chopping board on a flat surface. Distribute a pair of latex gloves and bull's eyes to each dissected student. Put the latex gloves on all the students and start the examination on the outside of the eyes. Have the students explain the texture of the eyes. Which part of the eyes can they identify? Why do you think that there are so many adipose tissues around the eyes? Tell the students that fat can protect your eyes from surrounding bones. Put the students slowly and carefully with fat with scissors. Below, students will find red muscle tissue. What do you think the muscles are doing to the students? There are four muscles in the cow that can move the eyes vertically and horizontally, and muscles that can turn their eyes towards clockwise and counterclockwise for human beings Tell the students that there are two.
