Document Summary

Somatosensation cutaneous and proprioception: exit the spinal cord via the ventral root. Interneurons can modulate the alpha motor neurons that are in motor pools. Skeletal muscle: golgi tendon reflex, stretch reflex. Small subset of descending systems: descending: inputs that are coming from higher neural structures (brain, premotor area and supplementary motor area can synapse with neurons in the motor cortex and brain stem. Can connect with local circuit neurons and alpha motor: can influence the activity of the alpha motor neurons in the spinal neurons cord (cid:523)(cid:498)final common path(cid:499)(cid:524, basal ganglia and cerebellum. Subcortical because its located below the cortex. Synapse with each other, premotor area, sma, brain stem. Influence activity of alpha motor neurons influence the contraction of skeletal muscles. Tracts connecting the brain and spinal cord (sc: periphery to cns afferent information. Information away from brain: cns to periphery efferent information.
