The two superficial veins of the lower limb are the
great saphenous vein and lesser saphenous vein
Which superficial vein ascends anterior to the medial malleolus of the tibia?
Great saphenous vein
Which vein ascends posterior to the lateral malleolus
Small saphenous vein
Which superficial vein empties into the femoral vein?
Great saphenous vein
Which superficial vein empties into the popliteal vein?
Small saphenous vein
Name the lower limb lymph nodes
Superficial Inguinal
Deep Inguinal
Popliteal
State the dermatomes of the lower limb
Why is the hip joint more stable than the shoulder joint
Deeper socket, with stronger and bigger muscles and ligaments.
What is the acetabular labrum?
Fibrocartilage that lines the acetabulum cavity
Which part of the acetabular cavity does the labrum cover- and what is its function
All around besides inferior, to support compressive load
Name ligaments of hip and function
1. iliofemoral- prevents hyperextension of the hip joint
2. pubofemoral- hyper abduction of the hip joint
3. ischiofemor - reinforces medial rotation
The movements at the hip joint are:
- Flexion
- Extension
- Abduction
- Adduction
- Internal Rotation
- External Rotation
- Circumduction (a combination of the above)

- iliacus
- Psoas major
- pectineus
