ANAT 321 Lecture Notes - Lecture 6: Basal Ganglia, Gyrus, Hypothalamus
Document Summary
Clinically important nerves: #5-trigeminal = clinically for carrying pain info from face + mouth so important for headaches. & pain in teeth: #7-facial = clinically for bell"s palsy - 1 side of face transiently paralyzed due to viral infection. *most nerves from brainstem & ventral surface of brain. Only nerve not from ventral surface - from top of brainstem & loop down. Control of 6 eye muscles by 3 cranial nerves. Outgoing originate from brainstem: spinal cord = dorsal horn for sensory input/ventral horn for motor output/middle for. Autonomic ns - visceral: brainstem = spinal cord open up to create 4th ventricle. *nuclei can extend large distance continuation of organization from spinal cord. Extend along brainstem & sensory axons can synapse at trigeminal nuclei. Cluster of neurons that send axons out to muscles for voluntary facial. Cluster of neurons both sensory & motor nuclei for ans. *sensory input from visceral organs [some #9 glossopharyngeal] /motor.
