Thigh Muscles: The thigh muscles can be divided into three segments-
3. Posterior Compartment
Anterior Compartment of Thigh Muscles
There are three major muscles in the anterior thigh – the sartorius, pectineus, and quadriceps femoris. In appreciation to these, the end of the iliopsoas muscle reaches into the anterior compartment.
Medial Compartment of Thigh Muscles
All the medial thigh muscles are supplied by the obturator nerve, that arises from the lumbar plexus. Arterial supply is via the obturator artery.
Posterior Compartment of Thigh Muscles
The posterior compartment of the thigh muscles is collectively identified as the hamstrings. They consist of the biceps femoris, semitendinosus, and semimembranosus.As the group, these muscles act to extend at the hip and flex at the knee. They are supplied by the sciatic nerve (L4-S3).
