What is the fold of the groin and what does it overlie?

The fold of the groin is a shallow curved groove that runs from the pubic tubercle to the anterior superior iliac spine. It overlies the inguinal ligament.

Where can I find the greater trochanter on the thigh?

What are the key bony landmarks at the knee that are palpable on the thigh?

Key palpable bony landmarks at the knee include the femoral and tibial condyles on the medial and lateral sides, the patella (kneecap) over the anterior knee, and the tibial tuberosity below the patella.

What is the ligamentum patellae and when is it best palpated?

The ligamentum patellae is a strong band connecting the patella to the tibial tuberosity. It can be palpated most clearly during knee extension.

What is the adductor tubercle and what structure is associated with it?

The adductor tubercle is a small bony projection located above the medial femoral condyle. The tendon of the adductor magnus muscle can be felt just above it.
