I.B.3 Gluteal Region & Thigh: Anterior Thigh: Page 1 of 3

Objectives:

2.3.1 Identify the muscles and nerves (sensory and motor) of the anterior thigh region. Describe the actions and nerve supply for each muscle.

2.3.2 Predict the motor and sensory deficits in the anterior thigh region that would result from damage to the nerves.

2.3.3 Trace the flow of blood from the common iliac artery to the thigh and knee.

2.3.4 Demonstrate the known collateral connections in the thigh and knee.

2.3.5 Trace the venous return from these areas to the inferior vena cava.

2.3.6 Identify the femoral triangle, femoral sheath, its origins and its contents, including the anatomical location of different groups of lymph nodes (whether or not they are seen on images), and afferent sources and efferent targets of each group. Indicate the relationship of the sheath and femoral hernias.

	Step 1: Start with the femoral nerve artery and vein. The anterior compartment of the thigh over lays these vessels and nerves.
	Step 2: Find the adductor hiatus and note how the femoral artery and vein pass through this opening.

	What is the name of the artery and vein after they pass through the adductor hiatus?
Popliteal artery and vein.

	Step 3: Add the vastus medialis.
	Step 4: Add the vastus intermedius.
	Step 5: Add the vastus lateralis.
	Step 6: Add the rectus femoris.

These muscles extend the leg at the knee joint. The rectus femoris also flexes the thigh at the hip joint.

Step 7: Add the sartorius which flexes the thigh at the hip joint and flexes the leg ant the knee joint.
