brain/spinal cord
for exercise phys
Question | Answer |
---|---|
motor cortex | executes movement plan |
vestibular apparatus | head position, linear and angular acceleration |
basal ganglia | initiation of slow movement |
thalamus | main sensory integration center |
cerebellum | initiates fast movement; coordinating and monitoring complex movements; aids in movement control in response to proprioceptors |
pons | reticular activating system; wakefullness to cortex; sensitivity to postural muscle control; large EPSP's and IPSP's to other neurons |
medulla | autonomic function; motor neuron decasation |
spinal tuning | further IPSP and EPSP to modify cerebral movement plan |
spinothalamic tract | afferent |
extrapyrimdal tract | controls neuromuscular tone, posture |
pyrimidal tract | corticospinal tract; rubrospinal tract; discrete movements; efferent |
cerebrum | organization of complex movements; storage of learned experiences; reception of sensory input; motor cortex initiates "movement plan" |
brain stem | (medulla, pons, midbrain) controls eye movement; muscle tone; postural control and tone; via extrapyrimidal tract |
