1
Q

The leg

A

Composed of two long bones
Tibia: larger, medial
Fibula: more delicate, lateral

2
Q

Synovial hinge joint of the knee

A

Formed btwn the medial and lateral condyles of the femur

Meeting the medial and lateral condyles of the tibia

3
Q

Medial and Lateral Menisci

A

Location: located btwn the condyles of the femur and tibia
Function: c-shaped dense fibrous pads, Assists in rotation of the knee and serves to spread synovial fluid within the joint

4
Q

Intercondylar Eminence

A

Location: btwn the tibial condyles
Function: attaches to the cruciate ligaments to provide stability in the knee joint.

5
Q

The tibia

A

Th weight bearing bone of the leg transmitting force btwn the femur and ankle.

6
Q

The fibula

A

Attaches muscles of the leg, it articulates only with the tibia and does not form a joint with the femur.

7
Q

Tuberosity of the tibia

A

Location: below the condyles of the tibia,
Function: prominent roughly triagnular, receives the tendon of the quadriceps femoris muscle via the patella ligament.

8
Q

Crest of the Tibia

A

Location: sharp anterior border
Function: subcutaneous (Directly below the skin)

9
Q

Interosseous Borer

A

Both on the tibia and fibula
Function: attachment for the interosseous membrane, contains oblique fibers, sloping down from the tibia towards the fibula.

10
Q

Interosseous membrane (function)

A

Permits attachment of various muscles found in the anterior leg

11
Q

Head of the fibula

A

Above the interosseous membrane,
Function: articulates with the lateral condyle of the tibia, form a gliding joint that is strengthened by surrounding ligaments of the kne joint.

12
Q

Medial Malleolus

A

Location: distal end of the tibia is expanded to form the prominent
Function: articulates with the talus bone of the ankle. Forms the major segment of the ankle joint

13
Q

Lateral Malleolus

A

Location: expanded dista end of the fibula

14
Q

Malleoli

A

Function: embrace the ankle joint on either side, thereby preventing undesirable side to side movement,

15
Q

Talus of the ankle

A

Receives the entire weight of the body from the femur and tibia, redistributing this force posteriorly to the calcaneus and anteriorly to the ball of the foot.
