Document Summary
Inner layer made of: white matter: myelinated axons, other prominent pathways for axons, corpus callosum, fornix, internal capsule. Meninges: protective layers of the cns, three layers, dura matter outer/most superficial, pia matter inner, closest to the brain, thin, csf fits & interfaces with blood stream, arachnoid matter - middle, looks like arms hanging down. Trigeminal (mastication & facial expression: olfactory (smell) Vagus (parasympathetic nerve: tongue, lingual nerve, second cervical nerve, cerebrum left hemispheres, fornix, third ventricle w/ choroid plexus, left cerebral hemisphere (cut away, right cerebral hemisphere. Don"t need to know location on this model, just function (not a good representation of location: cerebral cortex (gray matter) nerve cell bodies 25. Nervous system model (purple: olive, spinal cord (part cut away, arachnoid sheath, dura mater, eyeball. The brain model 3d: parieto-occipital sulcus. Somatomotor cortex precentral gyrus motor function. Lateral ventricle (anterior horn) choroid plexus and csf production. Olfactory tract (cranial nerve i) smell: & 98.
