Cow Eye Dissection Procedures 1.Use your scissors to cut off the pink or white fat/muscle around the cow eye. 2.Then, make a small incision in the sclera parallel to the iris on the side of the cow eye. Clear watery aqueous humor will drip out of the incision. 3.Continue to cut along the incision until the cow eye is cut into two separate pieces. 4.The big flat sphere is the lens. It is cloudy due to the death of the cells. The lens looks like a squashed yellow sphere. Gel-like vitreous humor surrounds the lens. 5.Take out the iris, the black cover with a hole in the middle. Flip the front part of the eye so that a black film cover is showing. Pull the thin film out with your hands and a tweezer. 6.The retina is a thin fleshy
Trim the skin off with a knife (Try to make them all the same width.)
The purpose of the fetal pig dissection was to understand the scientific process of dissection and gain hands-on experience of the internal and external anatomy of the fetal pig. In addition to this, the fetal pig dissection helps students better interpret the relative position and sizes of organs, as well relation between organ and organ system.
On the first day of the dissection, the main purpose is to skin the mink. First step to cut the mink is to make a V cut from the armpit of both arms to the neck. From the neck, a student made a cut down to the genital area. After the student made a lateral cut. Skinning the mink was easy after the down from neck to genital area. The group slowly cut skinned the skin away in order to see the muscles.
To continue, I then began to examine the endocrine system of the fetal pig. I began this dissection by finding the endocrine organs that are located in the area of throat. These organs were the thyroid and thymus. The thyroid’s responsibility is to produce amino acids that will help to regulate metabolism. The shape of the thyroid is oval like, and has a dark brown tint. The second endocrine organ found in the throat is the thymus. The thymus functions to provide immunity against diseases. It has a pink appearance, and is long in length. I was successful in finding three endocrine organs in the abdominal cavity. The first organ found was the adrenal gland. The function of this gland is to produce various hormones. This gland is identifiable
The biggest one was matching the organs with the pictures in the packet. Many times we found ourselves confused on if we were doing the correct thing or not, which is why we had to ask many questions and even go as far as asking our other classmates for help. Another issue that we encountered was with the tools we were given themselves. Although they were very sharp, it was hard to maneuver the blade around the pig. We often found ourselves having to switch equipment to get into the designated place. Another problem was figuring out how deep to go when cutting. The packet was not specific on how deep to cut into the fetal pig. We found ourselves damaging some of the internal organs. Damaging the internals organs affects the entire process of dissection. It changes everything of the dissection because the main point of this investigation is to identify them and not destroy them.
This paper considers that focused primarily on human iris. This choice of this topic was made due to interest of wanting to provide knowledge about the factors that determine eye color. I know, like hair or skin, brown eyes are dominant over blue eye genes. I also know that a person can be identified by the retina scanners because everyone has their iris with unique structural patterns.
The function of the Great Lyre with Bull’s Head is the funerary objects of the royal members, the female musician who joined the royal funeral ceremony used this lyre, and her body was near the royal figure; the lyre was buried with the female’s body. According to our instructor, “each person down there had a cup, got poison.” It means those musicians died for the royal family. They needed to service the royal members in the underworld, so the purpose of the lyre is to be the instrument of this female musician to play music for the royal
Sub-Point One: When preforming the surgery the surgeon will create a thin flap in the cornea using either a
In this experiment, the external and internal structures of a sheep’s heart was examined and identified by dissection. To determine the functionality of a human heart since they are both mammals.
"Beneath the bandages are two cotton pads, one for each eye ... Both pads are filthy and soaked with moisture. Bilaterally upper eyelids are sutured to lower eyelids. The sutures are grossly oversized for the purpose intended. Many of these sutures have torn through lid tissue resulting in multiple lacerations of the lids. There is an open space between upper and lower lids of both eyes of about one quarter inch, and sutures are contacting corneal tissue resulting in excessive tearing
For some, a black eye is a badge of honor, a symbol of having principles and being willing to fight for them. But for others, it’s an embarrassment – the result of foolishly walking into a door, challenging a guy named Bruno to a fight or going for a pony ride in a fire-snortin’ bronco known as “The Widow Maker”.
18) Looking into your microscope, you spot an unusual cell. Instead of the typical rounded cell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you realize that this cell is
You can also test for the other eye by closing your left eye instead. This time you should look directly at the black dot with your right eye, and as you move the test card closer to you, you should notice the cross disappear and reappear again.
A. Did altering the amount of light help in viewing the unstained cheek cells? Explain.
cell will look just like any other 'normal' cell although this is far from the
