Roger N. Morrissette, PhD. Brain Dissection Lab. By the end of this laboratory you should be able to do the following:.

The mid-sagittal cut is a straight forward dissection. Remove the pituitary gland. Turn the brain over. Align your knife or razor by placing it in the longitudinal fissure between the two hemispheres. Using smooth sawing motions, cut your brain in half. We begin our study of the mid-sagittal cut with the massa intermedia 25 , the point at which the two halves of the thalamus join across the midline.

Created on April 20, Cerebrum Performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. Corpus Callosum Connects the left and right hemisphere and ensures hemispheres can communicate with one another. Hypothalamus Plays a role in controlling behaviors such as hunger, thirst, sleep, and sexual response. Also regulates body temperature, blood pressure, emotions, and secretion of hormones. Performs many automatic functions like breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing. Cerebral Aqueduct Allows cerebrospinal fluid to flow between the third ventricle and fourth ventricle.

The sheep brain is remarkably similar to the human brain. One major difference, however, is in proportion. For example, the sheep brain has a proportionately smaller cerebrum. Another difference is in orientation of the spinal cord. The sheep spinal cord is orientated anterior to posterior, as in any four-legged animal. The human spinal cord is orientated superior to inferior. This orientation difference has a major affect on the location of the brain stem. The sheep brain stem is located more towards the rear posteriorly.

The sheep brain anatomy consists of 3 major parts — prosencephalon forebrain , mesencephalon midbrain , and rhombencephalon hindbrain. These 3 main parts of the sheep brain again divide into specific segments. There are also 5 different lobes in the sheep brain structure — frontal, parietal, occipital, temporal, and limbic area. The different anatomical features of the dorsal, ventral, and lateral aspects of the sheep brain make it complex. But, I will make it so simple for you that you may easily identify all the anatomical features of the sheep brain. Here, I will describe all the 3 major parts and their sub-parts from the sheep brain anatomy with the labeled diagram. I will show you the ventricular system of the sheep brain along with the course of cerebrospinal fluid CSF. Finally, I will provide a simple sheep brain dissection guide so that you can easily perform dissection and explore all its anatomical features. So, if you want to know the anatomical facts of the sheep brain cerebrum, cerebellum, brain stem, and different parts of meninges , continue this article till the end.
