The Brain plays a important role in our body, so in this lab we did a dissection of the sheep brain that is closer to the human brain. The steps we follow our teacher make every body couriose to learne about braine and see it structures before we remove the dura mater.We working in group lab and every body partecipation in the dissection of braine. Materials tray braine scissors scalpel probe plastic gloves Procedures Teacher gave to us breain sheep that before were stored in a prevervative into solution. We put on the glaves and cut the braine in the good direction and make that in two pices where we can see all the parts that located to the braine. Discussion Before beginning the dissection of the sheep brain we need to learne …show more content…
the terms used to specify the location and relative location of various brain structures. The teacher is illustrations of direction for cutting the braine in the middle in two equal parts that make that lab running with our interes. We cut in internal that means at the side of the brain, and closer to the side. So some structure that is quite in the middle can be lateral to another structure that is even closer to the middle of the brain. To summarize, anterior or rostral mean in the front or towards the front.
Posterior or caudal is at or towards the back. Lateral means on the side or towards the side. Medial is at or towards the middle. Dorsal means on top, in the brain and head only, and ventral means on the bottom, in the brain and head only. The braine is part of three divided that represent front, back and saggital planes which divides the left from right of braine. A horisontal planes divides the braine in to top and bottom position. The braine has three layers into exterior of the entire brain.1-meninges, 2-dura mater and 3-arachnoid layer and the pia mater. Meninges are the protective coverings, which enclose the braine and spinal cord. Dura mater remain near the base of the braine. Arachnoid layer, the middle layer and pia mater, the inner layer, are located to cover the braine. Another locate area referred to the brain stem that has inside pons, medulla, and celebellum. Pituitary gland was attached to our braine. Cingulate Gyrus, Lateral ventrice, fornix, septum pellucidum, cerebral acqueduct. and tegmentum are part we can see in the dissection of sheep braine. Conclousion This lab help us to be more familiarize with dimentional structure of braine.We challenged to our operation of the brain and we can see all the organs that located to the
brain.
The regions N, M, L and O are included in the cerebrum. These regions are the frontal lobe, parietal lobe, occipital lobe, and temporal lobes.
We know relatively very little about the complex organ called the brain. Our brain responds to nature's eternal external rhythms like seasons, tides, the sun and the moon. Animal instincts for survival are based on rhythms and drives of the brain. The brain is a collection of tissues that perform and respond to basic functions, desires and needs. The human brain is the most changed, enriched and complex brain through evolutionary terms, however, in its most basic form, it is the same as other brains of the Animal Kingdom. If one eliminates the cerebral cortex, one basically eliminates humanity and the brain becomes identical to that of a cat. If one removes even more, the brain becomes like that of an iguana.
The brain is a mystifying tissue that controls our bodies, conducting all the energy needed to make conscious and unconscious actions. This pink blob had always caught my attention during my earlier years and my interest had only spiked when my little brother became a victim of a horrible fall. The experience of seeing his brain deteriorate at such a fast pace awoke a passion and desire to learn more about the functions and genetic makeup of the incredibly powerful pink squishy tissue in our heads. By the time I was 13, I knew I definitely wanted to become a neurosurgeon to help study the dark and unexplored layers of the brain.
The cerebrum consists of two hemispheres, separated by a deep fissure called the Corpus Callosum, the hemispheres are divided into four lobes; the frontal, partials, occipital and temporal.
There are 4 main parts of the brain. Each part of the brain is responsible for different systems in our body.
The cerebrum has a gyrus structure, which means that that brain tissue is arranged in a convoluted manner. This gyrus structure allows for more brain surface area, which means brain tissue is present to perform
The two hemispheres of the brain are the left and the right hemisphere. Each having it's own unique purpose and function. The two hemispheres are separated by a fold down the middle connected only by a thick nerve cable called the corpus callosum. The Left hemisphere is thought to be the logical side controlling speech, reading, writing, details, facts, maths and science and rational, literal, practical analysis. The right hemisphere is seen as controlling the intuitive, creative side of life, with spatial perception, symbols and images, face recognition, imagination, beliefs and fantasy.

The brain is divided into four major lobes: the frontal lobe, parietal lobe, occipital lobe, and the temporal lobe. Each lobe contributes to cognitive development in young children.
The human brain is the control center of the human body. It is the most important part of the body, because without a brain, none of us would be alive. In the brain, there are the cerebrum, the cerebellum, and the brain stem. The cerebrum holds memories, controls movement, and does problem solving and thinking. It is the biggest part of your brain. The cerebellum is underneath the cerebrum; it controls coordination and balance. The brain stem is the part closest to the neck. It controls breathing, heart rate, blood pressure, digestion, etc. (Alzheimer's Assosiation, 2011). The brain has two hemispheres as well as the three major sections; the right hemisphere and the left hemisphere. There is not exactly a “music area” in the brain.
This paper involves how the brain and neurons works. The target is to display the brain and neurons behavior by sending signals. The nervous system that sends it like a text message. This becomes clear on how we exam in the brain. The techniques show how the brain create in order for the nerves about 100 billion cells. Neurons in the brain may be the only fractions of an inch in length. How powerful the brain could be while controlling everything around in. When it’s sending it signals to different places, and the neurons have three types: afferent neurons, efferent neurons, and the interneurons. In humans we see the old part of emotions which we create memories plus our brain controls heart beating, and breathing. The cortex helps us do outside of the brain touch, feel, smell, and see. It’s also our human thinking cap which we plan our day or when we have to do something that particular day. Our neurons are like pin head. It’s important that we know how our brain and neurons play a big part in our body. There the one’s that control our motions, the way we see things. Each neuron has a job to communicate with other neurons by the brain working network among each cell. Neurons are almost like a forest where they sending chemical signals. Neurons link up but they don’t actually touch each other. The synapses separates there branches. They released 50 different neurons.
Since the brain is extremely fragile and difficult to access without risking further damage, imaging techniques are used frequently as a noninvasive method of visualizing the brain’s structure and activity. Today's technology provides many useful tools for studying the brain. But even with our highest technology out there we do not know everything definitely. We do have fallbacks at times and these fallbacks can lead to serious problems.
The Central NS is broken down by two parts the brain and the spinal cord. The brain is protected by the scull and has a mushroom like shape. The bain has four main parts: the brain stem, cerebrum, cerebellum, and the diencephalon. The brain I the main organ
The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities. For instance, the occipital lobe in the back of our brain is responsible for processing vision, and the frontal lobe behind our forehead controls cognition and personality. The lobes of the brain are split between the right and left hemispheres of the brain. This well-designed arrangement is for the lobes to function correctly, so the two hemispheres of the brain can communicate with one
The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2. 75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body.
