Document Summary
Located just above the spinal cordoned regarded as enlarged extension of the spinal cord. Provide both somatic and visceral sensory and motor innervation of the head and neck: for the cranial nerves, know their names, numbers, functions (i. e. in general what do they do), whether they are sensory, motor or both. What does it innervate: iv (trochlearis) for m. obliquus superior, vi (abducens) for m. rectus lateralis, iii (oculomotor) for other 4 extrinsic eye muscles, eyelid raiser, pupil constriction, lens accomodation. Origin of neural activity that serves to increase arousal and readiness of other parts of the braun. A structure located in the hindbrain with many deep regular folds. Flocculonodular lobe: vestibulocerebellum helps regulate balance and eye. Spinocerebellum: helps regulate body and limb movements movements. Cerebrocerebellum: helps in planning movements and evaluating sensory info for action and has some purely cognitive functions. Superior colliculus and inferior colliculus: swelling on each side of tectum.
