36
Q

Bone on Lateral side of foot

A

Cuboid

37
Q

articulates with the talus and cuneiforms

A

Navicular

38
Q

most superior of all the tarsals;

articulates with the calcaneus situated over a bony projection called the sustentaculum tali

also articulates with the malleolar heads of the tibia and fibula forming a mortice joint, a.k.a. the talocrural joint

A

Talus

39
Q

Largest of the Tarsals

A

Calcaneus

40
Q

main functions are to convey the body weight to the ground and act as a level attachment for the calf muscle

A

Calcaneus

41
Q

Heel bone

A

Calcaneus

42
Q

Mortice Joint

A

Talocrural Joint of Talus

43
Q

Most superior of all the tarsals

A

Talus

44
Q

Bony projection of the Talus

A

sustentaculum tali

45
Q

medial side of the leg

principle weight bearing bone of the leg

(interosseus membrane connects tibia with fibula)

A

Tibia

46
Q

long and slender;

located on lateral side;

main function is to provide for the attachments of muscles

A

Fibula

47
Q

articulations of the phalanges

have one on the hallux or great toe
two on the rest (PIP and DIP)

all have collateral ligaments on the medial and lateral sides
interphalangeal ligaments on the plantar and dorsal surfaces;

motions include flexion and extension only.

A

Interphalangeal (IP)

48
Q

articulations of the phalanges and the metatarsals;
have collateral ligaments as well as plantar and dorsal metatarsophalangeal ligaments;

movements include flexion, extension, adduction, and abduction.

A

Metatarsophalangeal (MTP)

49
Q

Connect metatarsals at both the head (transverse metatarsal ligaments) and the base (plantar and dorsal ligaments);

shafts of bones connected by interosseous ligaments.

A

Intermetatarsal (IM)

50
Q

Ligament of Head of Metatarsals

A

Transverse Metatarsal Ligament

51
Q

A

Flexion
Extension

54
Q

articulations of the bases of the metatarsals with the tarsal bones
connected by dorsal and plantar tarsometatarsal ligaments;

A

TarsoMetatarsal

55
Q

movements include flexion, extension, adduction, and abduction

A

56
Q

articulations between the tarsals;

movements include gliding, flexion, extension, adduction, abduction, inversion, and eversion

the most important of these joints is the subtalar (articulation between the talus and calcaneus)-
movements here include pronation (combined abduction and eversion) and supination (combined adduction and inversion); there are many ligaments in the area such as the plantar calcaneonavicular, etc.
