arachnoid mater weblike middle layer of the three meninges
ascending tracts carry sensory information to the brain
ascending tracts pathways spinocerebellar, spinothalamic, dorsal column
Generates motor program for the muscles of the larynx, tongue,
Broca area function
cheeks, and lips for speaking
carry motor information from the direct pathway
CNS to effectors
bundle of nerve roots that occupy the vertebral canal from L2 to
cauda equina
S5
controls skeletal muscle movements, coordinates skeletal muscle
Cerebellum
contractions, maintains muscle tone for balance/equilibrium
conus medullaris cord tapers to a point inferior to lumbosacral enlargement
conus medullaris tapered inferior end of spinal cord
cranial nerve - abducens 6 - moves eyeball via extrinsic eye muscle (lateral rectus) - motor
cranial nerve - accessory 11 - movement of head - motor
7 - taste (anterior 2/3 of tongue), pain, touch, thermal sensation,
cranial nerve - facial
muscles of facial expression, secretion of tears/saliva - mixed
9 - taste (posterior 1/3 of tongue), monitors co2 / o2, monitors BP,
cranial nerve - glossopharyngeal
swallowing, saliva secretion - mixed
cranial nerve - hypoglossal 12 - speech, manipulation of food, swallowing - motor
3 - moves eyeball via extrinsic eye muscles; adjusts lens; constricts
cranial nerve - oculomotor

pulmonary, digestive, and urinary function - mixed
cranial nerve - vestibulocochlear 8 - hearing & equilibrium - sensory
contraction of extensor muscles in limb opposite of the one that is
crossed-extension reflex
withdrawn; Maintains balance by extending other leg
