20
Q
Fibular Artery
A
- Supplies lateral aspect of limb
21
Q
Vein Characteristics
A
- Floppy
- Muscles squeeze to push blood
- Contain valves to inhibit back flow
22
Q

25
Superficial Vein Pathway
- Dorsal venous plexus
- Lesser saphenous vein
- Popliteal vein
- Great saphenous vein
26
Fascia Lata
- Facial sleeve
- Continuous with inguinal ligament & inferior abdominal wall
- Covers whole leg
- Encloses all thigh muscles
27
Deep Fascia
- Divides shank into 3 compartments
28
Femur Head
- Round, articular surface
- Join with pelvis
- Create hip joint
29
Fovea
- Indentation on femur head
- Ligament attachment
30
Femur Components
- Head
- Neck

36
Acetabulum
- Form socket of hip joint
- 3 bones of os coxae
37
Posterior Pelvis Bones
