25
Q

List 3 characteristics of the talocrural joint?

A
  • synovial
  • uniaxial hinge

A

Cuboid

30
Q

How do you palpate the navicular tubercle?

A

Anterior and inferior to medial malleolus

31
Q

What does the navicular lie between?

A

Head of the talus & the 3 cuneiform bones

32
Q

On which surface of the calcareous is the sustentaculum tali found?

A

Medial aspect

33
Q

What does the posterior 1/3 of the dorsal surface of the calcaneous provide attachment for?

A

Achilles Tendon

34
Q

What does the lateral part of the neck of the talus provide attachment for?

A

ATFL

35
Q

What does the dorsal surface of the talus articulate with?

A

Lower end of the tibia?

36
Q

What does the inferior portion of the talus articulate with?

A

Calcaneous

37
Q

Which way does the head of the talus face?

A

Anterior
Inferior
Medial

38
Q

The longitudinal & transverse arch are formed by…

A

Tarsals and metatarsals

39
Q

How many tarsal bones are there?

Name them…

A 
7
Navicular 
Cuneiform (3) 
Talus 
Calcaneous 
Cuboid
40

A

Anterior Subtalar Joint

  • synovial
  • multi-axial
  • talonavicular part = ball & socket
41
Q

A

3
Anterior
Posterior
Medial

42
Q

46
Q

Which way does the talus glide during plantar/dorsi flexion?

Which was is difficult?

A

Plantar flexion: anterior
Dorsi flexion: posterior

Harder for talus to glide posterior due to structures behind it
