24
Q

Thigh bone

25
Femur proximal features
- Longest, strongest and heaviest bone in body - Head Greater trochanter Lesser trochanter
26
Femur distal features
Medial and lateral condyles Medial and lateral epicondyles Intercondylar fossa Patellar surface
27
Femur head
- Articulates with os coxae acetabulum - Fovea - Pit on head for ligament attachment
28
Femur neck
Distal to head
29
Greater and lesser trochanter
- 2 bumps at top area of femur - For attachment of muscles
30
Medial and lateral condyles
- Smooth rounded articular surfaces (tibia)
31
Medial and lateral epicondyles
- Projections superior to the condyles (muscle attachment)
32
Intercondylar fossa
- Deep posterior depression that separates the condyles
33
Patellar surface
- Smooth anterior region where the patella articulates
34
Kneecap bone
Patella
35
Patella characteristics
- Wrapped within tendon of quadriceps femurs muscle - Articulates with patellar surface of femur
36
Shin bones
Tibia and Fibula
37
Tibia and Fibula features
- Two bones that make up the crural region - Parallel to each other and connected by an interosseous membrane - Tibia is medial fibula - Tibia is the only weight-bearing bone
38
Bigger shin bone
Tibia
39
Tibia features
Medial and lateral condyles Tibial tuberosity Medial malleolus Ingerior articular surface
40
Tibial tuberosity
- Rough anterior projection inferior to condyles
41
Medial malleolus
Inferior most prominant medial process
42
Inferior articular surface
For articulation with talus
43
Fibula features
- Proximal head with flat articular facet for articulation with the tibia - Narrow neck and slender shaft - Distal end expands into lateral malleolus, which stabilizes ankle joint
