Sheep brain midsagittal view

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. This joining is not seen in all mammals, or even within all individuals of a species. In humans for instance, only one third of the population has this joining. Dorsal to the massa intermedia is the fornix Above the fornix, in our picture, is one of the lateral ventricles 8. It happens to be the left lateral ventricle. There are a total of four ventricles in the brain. The first ventricle is the left lateral ventricle. The second ventricle is the right lateral ventricle. The third ventricle 9 surrounds the massa intermedia.

It happens to be the left lateral ventricle.

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.

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. First, I would like to show you the different features of the sheep brain anatomy with the labeled diagram.

Dorsal to the massa intermedia is the fornix Movie Quotes. The regions are the same, the cranial nerves are the same, but fortunately for most of you, your brains are a bit larger and somewhat more complex than that of a sheep. Palomar College. Sheep Brain Dissection Video. The third ventricle 9 surrounds the massa intermedia. Exercise 1. When you have completed the video of the sheep brain dissection, read the complete laboratory and answer the questions on the Review Sheet at the end of the laboratory. This laboratory involves a video dissection of a sheep brain and the comparison of that sheep brain to other animal brains. Below, going straight down ventrally you will see the optic chiasm 23 sliced right through. Add to playlist. Observe one half of the brain and compare it to the labeled figure below.

.

The area in 21 is known as the genu while the area denoted by the number 22 is known as the splenium. The septum is a solid aggregation of neurons that is considered part of the limbic system. Good Luck. Cerebral Aqueduct Allows cerebrospinal fluid to flow between the third ventricle and fourth ventricle. Please print out these slides ahead of time and be prepared to take notes.
