Since we are unable to enjoyment benevolent passs for our dissection, sheep outlooks are often dissected as an assist to better understand the mammalian brain structure. However, because sheep brains discord from human beings brains, comparisons of their structures may not be precise. Objective 1. make out the major structures of the sheep brain; 2. Locate the larger cranial nerve of the sheep brain; 3. describe several differences and similarities between the sheep brain and the human brain. Hypothesis If we dissect the sheep brain, therefore we will have a better understan ding of similarities to a human brain. Materials * Sheep brain, probes, scalpel, gloves, water, dissection tray, check list, brain diagrams Procedures 1. Obtain a carry on sheep brain and sponge it thoroughly in water to pull back as much preserving fluid as possible. 2. Examine the break by dint of of the brain for the presence of meninges. If they are present finalize dura mater mater mater, arachnoid mater, and pia mater.

3. Remove any be dura mater by pulling it gently from the wax of the brain. 4. coif the brain with its ventral surface down in the dissecting tray and locate the following struct ures on the specimen: a. Cerebral ! hemispheres b. Convolutions c. Sulci d. longitudinal fissure e. anterior lobe f. Parietal lobe g. Temporal lobe h. Occipital lobe i. Cerebellum j. myelin oblongata Data and Observations Observations earlier to dissecting the brain we were able to locate many...If you unavoidableness to get a full essay, order it on our website: BestEssayCheap.com
