Final answer:
The gracilis muscle is not a member of the hamstrings, which are comprised of the semimembranosus, semitendinosus, and biceps femoris. (option a ,b ,c ,d)
Step-by-step explanation:
The student's question asks which of the following is not a member of the hamstrings: a. semimembranosus, b. biceps femoris, c. gracilis, d. semitendinosus.
The hamstrings are a group of three muscles located at the back of the thigh. These muscles include the semimembranosus, semimendinosus, and biceps femoris.
They are primarily responsible for knee flexion and thigh extension. Among the options given, the gracilis muscle is not a member of the hamstring group. Instead, the gracilis is a muscle that helps in adducting the thigh and flexing the leg, allowing you to cross your legs, as mentioned in one of the reference questions.
Hence, the answer is option a ,b ,c,d
