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.

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 skull, in order to compensate for this, has the foramen magnum located more towards the rear of the skull. In humans, since we walk upright bipedalism , the spinal cord is in a more vertical plane, thus the foramen magnum is located centrally on the bottom of the skull inferiorly.

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.

A slightly different bit of tissue, the pineal gland 5 is near the habenula, and, as the name implies, it is tissue that has some functions of a gland. Blood vessels should be dark while all of the myelin coated nerves will be white. Angola EC. Good Luck. Moving caudally identify the Cerebellum fine motor coordination with its medial section, the Cerebellar Vermis and its two lateral sections, the Cerebellar Hemispheres. Printable Worksheet. Add to playlist. All of this is part of the limbic system as well. Knee Joint Anatomy. Slightly more dorsal to this, hidden in the depth is a glimpse of the hippocampus Label the Model Human Cell. In humans for instance, only one third of the population has this joining. Hypothalamus Plays a role in controlling behaviors such as hunger, thirst, sleep, and sexual response.

The underside of the brain is called the ventral side. Your last and most difficult task is to identify as many of the 12 Cranial Nerves as you can.

Math Theorems and Constants EC. Align your knife or razor by placing it in the longitudinal fissure between the two hemispheres. Hypothalamus Plays a role in controlling behaviors such as hunger, thirst, sleep, and sexual response. Corpus Callosum Connects the left and right hemisphere and ensures hemispheres can communicate with one another. Brain Functions EC. You will find throughout this preparation that I have stated the functions of the individual brain region or nerve in italics and in parentheses just following that item. This is a tract and is denoted by number 19 , the anterior commissure , a much smaller version of the corpus callosum, which connects the lower portion of the two brain halves.
