A

Synovial Hinge Joints

18
Q

What are the 2 types of movement available at interphalangeal joints?

A

1) Flexion
2) Extension

19
Q

__________ ligaments offer support to the interphalangeal joints.

A

Collateral

20
Q

Bones of the foot form ______, which act as shock absorbers and distribute the stresses through the bones of the foot.

A

Arches

21
Q

What are the 3 arches of the foot?

A

1) Medial Longitudinal Arch
2) Lateral Longitudinal Arch
3) Transverse Arch

22
Q

What are the 4 components that maintain the arches of the foot?

A

1) Shape of interlocking bones
2) Ligaments
3) Fascia
4) Action of the muscles

23
Q

The arch of the foot that consists of the calcaneus, talus, navicular, 3 cuneiforms, and 1st through 3rd metatarsals. Does not normally come in contact with the ground and is more involved in propulsion than weight bearing.

A

Medial Longitudinal Arch

24
Q

The arch of the foot that consists of the calcaneus, cuboid, and the 4th & 5th metatarsals. More involved in weight bearing than propulsion.

A

Lateral Longitudinal Arch

25
Q

The arch of the foot that involves the whole length of the foot.

A

Transverse Arch

26
Q

What are the 3 portions of the transverse arch?

A

1) Anterior Portion
2) Middle Portion
3) Posterior Portion

27
Q

The portion of the transverse arch that runs from the head of the 1st metatarsal to the head of the 5th metatarsal.

A

Anterior Portion

28
Q

The portion of the transverse arch that runs from the 1st cuneiform to the cuboid.

A

Middle Portion

29
Q

The portion of the transverse arch that runs from the navicular to the cuboid.

A

Posterior Portion

30
Q

The thick, central connective tissue on the sole of the foot that attaches between the medial calcaneal tubercle and the proximal phalanx of each toe. It is actually continuous with the fascia of the calf.

A

Plantar Fascia (aka. Plantar Aponeurosis)

31
Q

As the toes extend (primarily the 1st), the plantar fascia tightens because it crosses the MTPs. As it tightens, it pulls the calcaneus anteriorly and elevates the arches, putting the foot into a position of supination.

A

Windlass Mechanism of the Foot

32
Q

What process will occur with the foot whether the action is active, passive, weight-bearing or non-weight bearing?

A

Windlass Mechanism of the Foot
