Question

multiple choice question
which of these is a long, thin muscle that crosses the anterior thigh and helps to flex the thigh?
psoas major
adductor longus
iliacus
sartorius

Explanation:

The sartorius is a long, thin muscle that crosses the anterior thigh and is involved in thigh - flexion. The psoas major is more deeply located and not as long and thin in the anterior thigh context. The adductor longus is involved in adduction rather than just flexion. The iliacus is also related to hip flexion but is not the long, thin muscle crossing the anterior thigh like the sartorius.

Answer:

Sartorius
