spinal cord

gray matter structure

made of neuronal cell bodies

gray matter function

responsible for processing info

white matter structure

made of myelinated axons

white matter function

transmits info throughout the brain and spinal cord

ventral horn structure

anterior part of gray matter that contains cell bodies for motor neurons

ventral horn function

responsible for voluntary movement and reflexes

dorsal horn structure

posterior part of the spinal cords gray matter

dorsal horn function 

process and transmit somatosensory information, such as touch, pain, temperature, and proprioception, from the body to the brain

ascending

dorsal, sensory impulses to the brain

descending

ventral, motor impulses from the brain to motor neurons reaching muscles and glands

damage to ascending

loss of sense/feeling

damage to descending

difficulty with voluntary movement

tracts

axons that provide two way communication between the brain and body parts

Spinothalamic Tract

sends impulses from the spinal cord to the thalamus
