Sheep brains, like other sheep organs, are much smaller than human brains, but have similar feature. They can be a valuable addition to your study of anatomy.
See for yourself what the cerebrum, cerebellum, spinal cord, gray and white matter, and other parts of the brain look like with this sheep brain dissection guide! Use this for a high school lab, or just look at the labeled images to get an idea of what the brain looks like.
You’ll need a preserved sheep brain for the dissection. Set the brain down so the flatter side, with the white spinal cord at one end, rests on the dissection pan. Notice that the brain has two halves, or hemispheres. Can you tell the difference between the cerebrum and the cerebellum? Do the ridges (called gyri) and grooves (sulci) in the tissue look different? How does the surface feel?
Turn the brain over. You’ll probably be able to identify the medulla, pons, midbrain, optic chiasm, and olfactory bulbs. Find the olfactory bulb on each hemisphere. These will be slightly smoother and a different shade than the tissue around them. The olfactory bulbs control the sense of smell. The nerves to the nose are no longer connected, but you can see nubby ends where they were. The nerves to your mouth and lower body are attached to the medulla; the nerves to your eyes are connected to the optic chiasm. Using a magnifying glass, see if you can find some of the nerve stubs.
Spindle fibers extend from the poles and overlap at the spindle equator where some attach to chromosomes to help separate them during cell division.
<h3>What is spindle fiber?</h3>
A single filament that travels from the poles to the center is a spindle fiber. Aster is a single filament as well, but the aster differs in its placement.
<h3>What is spindle equator?</h3>
Chromosome alignment at the spindle equator improves the efficiency of bi-orientation. Chromosome congression, a procedure that moves chromosomes from close to spindle poles to the equator, is necessary for this alignment to take place.
<h3>What is spindle in cell?</h3>
A protein structure called a spindle fiber divides a cell's genetic material.

Answer:
chromosome
Explanation:
A chromosome consists of entire set of genes with in an organism’s total population.
DNA with is a chromosome is arranged in a discrete short and wide units. A chromosome consists of millions of DNA base pairs which consists of large number of genes. The chromosome structure comprises of double helix DNA wrapped around proteins. DNA with in chromosome provide basis for chromosome synthesis.
