Because of reciprocal inhibition,which of the following muscles is inhibited when flexion of the thigh at the hip joint occurs?

Question

Quizplus · Accepted Answer

Reciprocal inhibition is a neural mechanism where the contraction of one muscle group is accompanied by the relaxation, or inhibition, of its antagonist muscle group. In the case of flexion of the thigh at the hip joint, the hamstrings (including semitendinosus) are the agonist muscles, while the quadriceps (including rectus femoris) are the antagonist muscles. Therefore, the correct answer is B, semitendinosus, as it is an agonist muscle opposite to the quadriceps. The other options are not relevant or do not have an antagonist relationship with the quadriceps in hip flexion.
