Question

55 multiple choice 1 point which of the following muscles is located both medially and posteriorly on the thigh? adductor magnus adductor longus pectineus semimembranosus clear my selection

Explanation:

• Adductor magnus: It is located medially and posteriorly on the thigh. It has both adductor (medial - related function as adduction is movement towards the mid - line) and extensor (posterior - related in terms of thigh extension) components.
• Adductor longus: It is mainly a medial thigh muscle and is not located posteriorly. Its main function is adduction of the thigh.
• Pectineus: It is located on the anterior - medial aspect of the thigh, not posteriorly. It is involved in hip flexion and adduction.
• Semimembranosus: It is a posterior thigh muscle (part of the hamstring group), but it is not located medially in the sense of being an adductor - type medial location. It is more on the posterior - medial (but in the context of the question's comparison with adductor magnus which has a more prominent adductor - medial and posterior location, it is not the best fit).

Answer:

A. Adductor magnus
