Excitation of the quadriceps femoris group and inhibition of the hamstring group is termed _______ innervation.
A)antagonist-effector
B)ipsilateral
C)crossed-extensor
D)reciprocal
E)Intersegmental

Question

Quizplus · Accepted Answer

Reciprocal innervation refers to the process of exciting a group of muscles while inhibiting their antagonist muscles. In this case, the quadriceps femoris group is excited while the hamstring group is inhibited, making D the correct answer. Antagonist-effector refers to the relationship between agonist and antagonist muscles, ipsilateral and crossed-extensor refer to the location of nerve pathways, and intersegmental refers to the communication between different segments of the spinal cord.
