Question 1

what are multipolar neurons?

Answer 1

“The steryotypical neuron”; has one axon and multiple dendrites and is most common in the CNS. (NOT a sensory neuron)

Examples:

motor cells in anterior and lateral horns of the spinal cord and autonomic ganglion cells

Question 2

what is the function of somatamotor neurons (GSE)?

Answer 2

Function: conduct impulses to skeletal muscles of the body

Found in: anterior horns of the spinal cord or motor nuclei of cranial nerves.

Question 2

what is the function of Visceromotor (GVE) neurons? What are their types?

Answer 2

Visceromotor (GVE) conduct impulses to glands, blood vessels, and smooth muscles.

Preganglionic sympathetic:found in the lateral horn of the spinal cord (IML in T1-L2).

Postganglionic: in the sympathetic ganglia.

Preganglionic parasympathetic located in parasympathetic nuclei of cranial nerves and sacral parasympathetic n. of the spinal cord (S2-S4).

Postganglionic neurons are found in parasympathetic ganglia.

(Viscero, so vitals, so glands and blood vessels)

Question 3

What are the functions of the Somatosensory and viscerosensory neurons

Answer 3

receive
stimuli from the external and internal environment (spinal or cranial nerves ganglion cells).

Question 4

What are interneurons?

Answer 4

interconnect motor or
sensory neurons within the central nervous system.

(from the name.)
