Back

The gemellus inferior inserts on the medial surface of the greater trochanter.

Front

Which muscle connects the anterior surfaces of the lumbar vertebrae to the lesser trochanter?

Back

The psoas major connects the anterior surfaces of the lumbar vertebrae to the lesser trochanter.

Front

What hip movement lengthens the fibers of the gluteus minimus?

Back

Adduction of the hip lengthens the fibers of the gluteus minimus.

Front

What is the primary function of the obturator internus muscle?

Back

The primary function of the obturator internus muscle is to laterally rotate the hip.

Front

What are the main components of the hamstring muscle group?

Back

Front

What is the anatomical significance of the greater trochanter?

Back

The greater trochanter serves as an important site for muscle attachment and is involved in hip movement.

Front

How does adduction affect the gluteus minimus?

Back

Adduction of the hip causes the gluteus minimus to lengthen, which can affect its function in stabilizing the pelvis.
