Mammalian Brain Dissection Purpose: The purpose of dissecting the sheep brain is to learn the structure of the brain. We must learn a brains structure to help us learn its functions‚ because they are very important and part of the Central Nervous System. We must learn the Central Nervous System to learn how it communicates between different parts of the body and the body’s interactions with the environment because it is a California standard. Analysis Questions: 1.) What observable features

I. Fetal Pig Dissection II. Purpose Sus scrofa‚ or the domestic pig is a member of the class Mammalia and the order Artiodactyla. Since we as humans are also a member of class Mammalia‚ we have a good deal in common biologically with pigs‚ although we might not like to think so. Since we have a good deal in common‚ it is very helpful for us to study these animals both anatomically and physiologically. We do this when we test medicines on pigs‚ perfect surgical procedures on pigs‚ and even when

Structure and Function of the Body: Heart Dissection This assignment will describe my personal experience whilst participating in a heart dissection. It will explain the internal and external heart structure and detail the structure of blood vessels in relation to their function. This assignment will also describe what I did‚ saw and felt during my participation. My first thought when the sheep’s heart was given to our group was how fatty it looked to be. At first glance‚ the heart seemed

Dissection is a common practice among high schools in the biology class. With new technology arising‚ there has been many debates that have been presented looking at the pros and cons of such behaviour. Millions of animals are killed annually‚ there are little to no control measures in place‚ and animals suffer for the use of dissection among students. In the United States‚ six million frogs are dissected annually in high schools. An additional amount is used in elementary and universities across

Cow Heart Dissection By: Ashley McAllister 3/16/2014 Ashley McAllister Anatomy Miss Reilmann March 16‚ 2014 Cow Heart Dissection A. Background Information When the class dissected the cow heart last Thursday there were a lot of different things that could be seen. The purpose of this particular dissection was to see how the heart worked and pumped blood so that the body was able to receive the nutrients and oxygen it needed to survive. The cow heart and a human heart are alike

Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

Aortic Dissection An aortic dissection is a tear in your aorta. The aorta is the main blood vessel that carries blood out of your heart to supply the rest of your body. It comes out of your heart and curves around‚ then goes down through your chest (thoracic aorta) and into your belly (abdominal aorta). The wall of the aorta has inner and outer layers. Aortic dissection occurs most often in the thoracic aorta. This is more likely to happen if the inner layer of the aorta has a weak spot or gets
