Question

The functional efficiency of a muscle depends upon its:
a.Nerve stimulation
b.Girth
c.Fiber quality
d.Tonus

Answer 1

Answer:

nerve stimulation

Explanation:

this is because. without nerve stimulation muscle will not perform its activity

Answer 2

Answer:

The functional efficiency of a muscle depends upon it's Girth (b).

Explanation:

The size of a muscle's cross-sectional area is directly proportional to its strength.

Axons with a larger diameter have a faster action potential velocity.

The internal resistance of a fiber reduces as its diameter increases. The internal resistance reduces quicker than the membrane resistance, hence a larger diameter increases the distance the membrane potential can travel.
