Document Summary

Antagonist: critical for the function of motor control. It crosses at the lower medulla it decussates (85-95% of them) Lower regions we have bilateral distribution down to spinal cord. Excitatory output to extensor muscles vestibular nuclei: goes to extensor muscles only. Overview of motor control n o i t. Cerebral cortex p e c o i r p o r p i s u o c s n o c h c u o t l i a c s n m e. Tract n o i t p e c o i r p o r p r a l l e b e r e c o n p. Spinal cord (spinal reflexes: looking at the control of the right side of the body same thing happens in reverse for, commands form cerebral cortex (primary motor cortex) which sends info down left side of the body.
