01 / Location & anatomical relationships
Between the hip and knee.
02 / Structure & organization
The femur supports anterior, medial and posterior muscle compartments. Quadriceps extends the knee, adductors draw the thigh toward the midline, and hamstrings contribute to hip extension and knee flexion.
03 / Function
It contains the femur and large muscles that move your leg.
04 / Mechanism
The femur forms its strong central support. Quadriceps muscles at the front help straighten the knee, while hamstrings at the back help bend it. Other thigh muscles move the leg toward or away from the body.
Part of a bigger picture
The thigh belongs in our legs & feet collection. Explore the nearby parts to see how this area of the body fits together.

Connect structure with function
A muscle crossing two joints can act differently depending on joint position. This is especially relevant when studying the hamstrings and rectus femoris.
Check your understanding
Locate the thigh in relation to its neighbors. Explain how the structural features described above support its function, then distinguish it from a nearby structure with a different role.
