Q

What’s the difference between the ellipsoid and condyloid joint?

A

Both move in two axis

Ellipsoid joint = angle of movement in axis is very similar

But condyloid = the angles of movement between the axis differ greatly
Ie. lateral/med roataion is much less than extension and flexsion of knee

Q

Explain the movements of the hip joint and it’s function

A

PCL: PRVENT the anterior slide of femur ON the tibia

ACL: hyperextension. Prevents posterior slide of femur on tibia

Lateral collateral = prevents adduction

Medial collateral = prevents abduction

17
Q

Name the bones involved in the function of the ankle joint

A

Tibia and fibula distal

18
Q

Name the bones involved in the function of the sub talar joint

A

Tarsals (articulation between talus and calcaneous)

19
Q

Indentifh the bone regions of the tarsals

A

Talus (ankle bone) and trochanter surface
Clacanous (heel) and tuberosity
Navicular and tuberosity
Cuboid
Cuneiform (medial, intermediate, lateral)

20
Q

Identify the bone regions of the metatarsals and phalanges

A

Head
Shaft
Base (tuberosity)

21
Q

What movements can be done by sub talar joints?

A

Ball socket

Inversion and eversion

22
Q

What movements can be done by the ankle joint

A

Hinge joint (1 axis)

Dorsiflexsion and plantar flexsion

23
Q

Identify the ligaments and membranes of distal leg and ankle joint

A

Interosseous membrane
Anterior and posterior tibiofibualr ligaments
Deltoid ligament
Lateral collateral ligaments (ant and post talofibular lig, calcaneofibualr lig)

24
Q

Explain the significance of the ligaments of the ankle joint

A

Lateral collateral ligaments: limiting eversion

Medial collateral ligs : limit inversion

Anterior tibiofibular ligs : stabilise the ankle joint
