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 |
