Sheep Brain Dissection Lab Report

The nineteenth century saw an explosion in knowledge regarding the brain unlike any before. For centuries, the brain had been considered the seat of human intelligence. However, the brain of the classics was a singular organ of

VII) Describe how the shape of the thalamus and brainstem reflect the presence of impinging cortical structures along the antero-posterior axis. Describe the difference between sheep and human brains.

The human mind is the center of a person’s reasoning and thoughts and today it has gone from a mystery to a unique feature in the human anatomy. The mind is home to one's consciousness, perception, thinking, judgement, and memory. The brain also controls a person's muscle movement, breathing, and even their body temperature. Its anatomy is so complex that many doctors and scientists are continually learning and understanding how the different features of the brain work together to function as one of the body’s most interesting organs. Those who do study the way the brain and the nervous system function together are quite brilliant and are one of the most dedicated group of doctors. There are many fields

Secondly, the brain is an immensely complicated organ to understand and study. It is composed of major parts, lobals, systems, glands, cells, tissues. Each piece

In Allan Jones’s presentation, A Map of the Brain, he explains his current project and why is essential to the modern day. Jones first starts off by giving the audience some background information about the brain. He states that the brain is a complex organ that receives around twenty percent of the blood from our hearts as well as twenty percent of the oxygen from our lungs. Jones explains that the brain is essential to the body because it controls everything we do. Even though the brain is very complex, it does not mean that it is not organized and structured. In the past century, scientists have created a blue stain that stains neuron bodies. This showed scientists that neurons were unevenly distributed throughout the brain depending on

The brain is a soft, delicate, non-replaceable and spongy mass of tissue. Brain is considered as a kernel part of the body and has a very complex structure. The brain consists of mainly two types of tissues: gray matter (GM) and white matter (WM). The brain also contains a cerebrospinal fluid (CSF) that consists of enzymes, glucose, salts, and white blood cells. The brain is divided into three major parts, the hindbrain (including the cerebellum and the brain stem), the midbrain, and the forebrain (including the diencephalon and the cerebrum).The body is made up of many

The brain is the most complicated part of the human body. I will begin explaining certain parts and their

Imaging tests, such as a CT scan or MRI. These are used to create a picture of the brain.

Research is playing with puzzles, making sense of the nonsensical piece by piece. What’s a greater puzzle than the brain? In middle school, to procrastinate, I watched videos on why we dream, why we feel, why we forget. The more I saw, the more I wanted to know. So, in high school, I enrolled in AP psychology. When I read the syllabus, my stomach cartwheeled at knowing I would have to dissect a sheep brain. As I reluctantly walked into the lab, the fresh formaldehyde smell battered my nostrils. Little tool kits of torture were lined up on every table. While the rest of my group used them to emphatically scissor away, I simply observed, hands paralyzed to my side. Then, the teacher commanded each of us look at the hippocampus. When I picked up the grooved grey blob, I realized my slightly shaking forceps held most of that sheep’s knowledge, memories, and

At first, the idea of dissecting a brain excites me but the moment it was there, I was hesitant to hold it first because I was afraid of how it feel to hold a human brain. However, as our examination of the brain parts went along, I finally had the courage to touch it and sense its surfaces. Honestly, being a novice in identifying the parts of the brain was a challenge for me, or for the most of us. My groupmates and I had a difficulty in identifying the specific location of its parts since our reference was from google images and a phone application. In result, for every part that we will identify, it took us almost more than a minute to discover the right place of a certain part. The

The human brain is a mystery that has been studied for centuries in attempt to understand how it functions. Scientists first thought that the brain was a structure that functioned a whole. It was in the early 1600’s where the first ideas of localisation of function in the brain started. At this time Rene Descartes discovered a tiny structure called the pineal

There were three general approaches to mapping brain functions. With extirpation, parts of the brain are systematically destroyed to observe the subsequent behavior (Marshall Hall and Pierre Fourens). In the clinical method, the researcher looks at the brains of people after they died who exhibited odd behavior in life (Paul Broca). Finally, electrical stimulation of the brain and body was used to observe the muscle twitches (Fritsch and Hitzig).

The physical parts of the brain made it a little bit harder for it to be studied. On normal examination, the brain appears to look like a mass of gelatin. In the seventeenth century, the creation of the microscope really helped scientist to visualize different parts of neurons and glia. Throughout the 1800-1900’s there were tons of beliefs and theories of what the brain makes up. Scientist worked hard to discover the brain's connection to cognition, movement, sensation, and emotion (Society for Neuroscience).
