question 34

Multiple Choice

• A) By modulating the density of the alpha motor neurons synapsing in the neuromuscular junctions
• B) By modulating the entry of calcium into the muscle during stretch
• C) By modulating the sensitivity of the Golgi tendon organs
• D) By changing the density of calcium-activated potassium channels
• E) By modulating the density of spiral endings of Group Ia and II afferents around the nuclear chain fibers
