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. can you tell the difference between the cerebrum and the cerebellum? you’ll probably be able to identify the medulla, pons, midbrain, optic chiasm, and olfactory bulbs. these will be slightly smoother and a different shade than the tissue around them. using a magnifying glass, see if you can find some of the nerve stubs.

2. use the labeled picture to identify the corpus callosum, medulla, pons, midbrain, and the place where pituitary gland attaches to the brain. use your fingers or a teasing needle to gently probe the parts and see how they are connected to each other. 3. look closely at the inside of the cerebellum. you can see gray and white matter in the cerebrum, too, if you cut into a portion of it. follow the same procedure with a section of the cerebellum, then compare and contrast the two. the kids had a fun time with this hands on experience and it was great to actually be able to locate and see different sections of the brain. just place your order while logged in to your home science tools account and you’ll automatically earn up to 6% back when your order ships!

dissection tools and tray, lab gloves, preserved sheep brain. and find the arbor vitae, so named because its white matter form a pattern that resembles a tree. introduction. the purpose of the sheep brain dissection is to familiarize you with the three- locate important structures in the sheep brain will be of great benefit to understanding how structures notice the pattern of grey and white matter. nervous system by dissecting a sheep’s brain to familiarize ourselves with key brain structures. pattern of gyri and sulci are not the same as the right side., sheep brain dissection guide, sheep brain dissection guide, sheep brain dissection quiz, sheep brain dissection lab report introduction, sheep brain dissection quizlet

you can still see some structures on the brain before you remove the dura mater. take special note of the pituitary gland and the optic chiasma. the pituitary gland and the optic chiasma are still intact. the infundibulum (pituitary stalk) is now visible in the center. often these two nerves are removed with the dura mater, but in this image they are still intact. 4. if you flip the brain over to the other side, you can see the cerebellum, it will be loosely attached to the cerebrum in most cases. the convolutions of the brain are also visible as bumps (gyri) and grooves (sulci).

in this image, a student is bending the cerebellum down to show the superior and inferior colliculi. 6. using a scalpel and the longitudinal fissure as a guide, the brain is separated into the left and the right hemispheres. always leave the specimen in the dissecting tray when cutting it, do not hold it in your hand! the cerebrum will still be visible as a wrinkled structrure, and you can even locate the “bumps” of the superior and inferior colliculi. remember, you located those structures by pulling down the cerebellum. 8. once the brain is cut this way, the colliculi can also be seen from the inside and the pineal gland is revealed only if you made a very careful incision. the fissure between the cerebrum and the cerebellum is called the transverse fissue.

learn the external and internal anatomy of sheep brains with hst’s learning center science lesson and guide! diagram worksheets also included. view now! while we are using the sheep brain for dissection, this guide will highlight the similarities between the being able to locate structures in the sheep brain will help you to quickly image the brain after head injury, identify the pattern of blood list and describe the principal structures of the sheep brain. 2. dissection tools and trays, lab aprons, safety glasses, lab gloves, preserved specimen, paper towels, identify the white matter pattern, or arbor vitae, of the cerebellum. 4., longitudinal fissure sheep brain, infundibulum sheep brain, infundibulum sheep brain, cerebral cortex sheep brain, in the sheep brain the cerebellum is rostral or caudal, sheep brain dissection guide, sheep brain dissection quiz, sheep brain dissection lab report introduction, sheep brain dissection quizlet, longitudinal fissure sheep brain, infundibulum sheep brain, cerebral cortex sheep brain, in the sheep brain the cerebellum is rostral or caudal

2. observe the outer membrane (dura mater). 3. cut off the dura mater and expose the cerebrum. 4. identify the longitudinal fissure, which separates the right and left hemispheres of the brain. 5. locate the frontal, 2 parietals, 2 temporals, and the occipital lobes of the brain. 7. locate the optic chiasm, pons, cerebellum, medulla oblongata, olefactory bulbs, and the optic nerves.

use the longitudinal fissure as a cutting guide. 3. return your attention to the midsagittal section. 4. locate the pineal body and optic chiasma. it appears as a circle of gray matter surrounded by the shallow section of the third ventricle. 1. name some similarities between the human brain and the sheep brain. 2. discuss some differences between the human brain and the sheep brain.
