Question

What is the major difference between alpha and gamma motor neurons?

a. Alpha motor neuron releases acetylcholine, gamma motor neurons releases GABA

b. Alpha motor neuron innervates Golgi tendon organ, gamma motor neuron innervates stretch receptor

c. Alpha motor neuron innervates skeletal muscle fibers, gamma motor neuron innervates smooth muscle and gland

d. Alpha motor neuron innervates intrafusal muscle fibers, gamma motor neuron innervates extrafusal muscle fibers

e. Alpha motor neuron innervates extrafusal muscle fibers, gamma motor neuron innervates intrafusal muscle fibers

Explanation / Answer

ANSWER IS (E)

gamma motors only innervates the intrafusal muscle fibre where as alpha motor nueron innervates extrafusal muscle fibers.

An alpha motor neuron is the type of neuron that stimulates the skeletal muscles and is under voluntary control. gamma motor neurons are involved in reflexes and are involved in adjusting the tension on muscle spindles.
