10/31 - 11/3
Exercise 19: Gross Anatomy of the Brain and Cranial Nerves
Be able to define: central nervous system, peripheral nervous system,
somatic division (nervous system), autonomic nervous system.
On brain and brain models be able to identify: gyri (gyrus), sulci (sulcus), longitudinal
fissure, central sulcus, frontal lobe, parietal lobe, occipital lobe, temporal
lobe, lateral sulcus, postcentral gyrus (pirmary somatosensory cortex),
precentral gyrus ( primary motor cortex), olfactory bulbs and tracts, optic
chiasma, optic tracts, pituitary gland, mammillary bodies, pineal gland,
thalamus, hypothalamus, infundibulum, corpus callosum, fornix, septum pellucidum,
pons, corpora quadrigemina (superior and inferior colliculi), ventricles
(lateral, 3rd, 4th and cerebral aqueduct), choroid plexus, cerebellum (vermis,
arbor vitae), medulla oblongata, decussation of pyramids.
You do not have to memorize all the association areas or the basal nuclei. What
functions are associated with the right hemisphere? With the left?
Meninges: know where you would find the dura matter, arachnoid (mater)
and pia mater. On the head models be able to locate the dural sinuses: superior
sagittal, transverse, sigmoid and occipital. Be able to trace the path of the
cerebrospinal fluid from the choroid plexes to the arachoid villi.
Cranial nerves: On brain model be able to identify all 12 pairs of
cranial nerves, and give their names and functions.
Sheep brain: On the sheep brain be able to identify: olfactory bulbs,
optic chiasm, mammillary body, pineal gland, pons, cerebrum, cerebellum,
pituitary ( if possible), dura mater, superior and inferior colliculi, corpus
callosum, thalamus, fornix, medulla oblongata.
Exercise 18B: Neurophysiology of Nerve Impulses: Computer Simulation The
usual warnings apply! Be sure to do this experiment and to answer the associated
review questions!
