Question 1

What is the anatomic type,location and type/distribution impulses, of Somatic efferent neurons.

Answer 1

Multipolar. Brain: cranial nerve motor nuclei. Spinal cord: anterior gray column. Motor to skeletal muscle.

Question 2

What is the anatomic type,location and type/distribution impulses, of Visceral efferent neurons.

Answer 2

Multipolar.

• Brain: motor Nuclei of cranial nerves 3,7,9,10
• Spinal cord: lateral great column in sacral region
• Autonomic ganglia
• Motor to smooth muscle, cardiac muscle, and glandular epithelium
