1. What do the dorsal, lateral, and ventral funiculi of the spinal cord represent?
2. Which statement best describes the general function of descending spinal pathways?
3. Which spinal cord column contains specific ascending sensory tracts in the dorsal white matter?
Spinal cord funiculi — locations?
Dorsal, lateral, ventral columns.
Funiculi — function?
Contain white matter tracts for signal transmission.
Ascending tracts — role?
Carry sensory info toward the brain.
Descending tracts — role?
Convey motor commands from brain to spinal cord.
Spinothalamic pathway — function?
Transmits pain and temperature to the thalamus.
Third-order neuron — location?
In the thalamus, relays to cortex.
