Exercise 15 The Brain and Cranial Nerves:Learning Outcomes1.Activity 5.10 Perform microscopic observation of the neuron structure;summarize functions of neurons in nervous (neural) tissue.2.Activities 15.1–15.4 Dissect and identify the major anatomical structureson the human brain and compare its structure with that of a sheep brain.3.Activity 15.5 Identify the brain ventricles and describe the flow ofcerebrospinal fluid.4.Activity 15.7 Locate the origins of the cranial nerves on the brain.5.Activities 15.8–15.10 Evaluate the functions of the cranial nerves.6.Activity 15.11 Identify the openings in the skull through which the cranialnerves exit the cranial cavity.Exercise 5.9 and 14.1 TCell Types in Nervous Tissue:Learning OutcomesWhen you complete the activities, you should be able to:1.Activity 14.1 Discuss the structure and function of the different types ofneurons and neuroglia.
