Q

Transverse arch location

A

The transverse arch is located in the coronal plane of the foot

19
Q

The transverse arch is formed by:

A
  • The metatarsal bases
  • The cuboid
  • The three cuneiform bones
20
Q

The transverse arch exists as a result of:

A

Difference in height between the medial and lateral arches

21
Q

Muscular support of the transverse arch

A

Fibularis longus and brevis
Tibialis posterior
Transverse head of hallucis longus

22
Q

Ligamentous support of the transverse arch

A

Deep transverse ligament

Interosseous ligament Spring ligament

23
Q

Bony support of the transverse arch

A

The wedged shape of the bones of the arch

24
Q

Describe the motion of a walking human

A

Bipedal locomotion, characterised by an ‘inverted pendulum’ motion, in which the body vaults over the non-moving limb.

25
Q

Design Considerations for Bipedal Gait and Upright Posture

A
  • Stability in upright posture
  • Ability to raise & control trunk
    over hindlimbs
  • Ability to balance on one leg
  • Walk with feet underneath body
26
Q

What is the human gait cycle?

A

The time interval between two successive occurrences of one of the repetitive events of walking

27
Q

Phases of the human gait cycle

A
  • Stance phase (Foot on ground)

- Swing phase (Foot off ground)

28
Q

Stance phase

A
  • 60% of the gait cycle

- Divided into heel strike, support, and toe-off

29
Q

Swing phase

A
  • 40% of gait cycle

- Left lift and swing

30
Q

The stages of walking

A 
Heel strike
Mid(Support)
Toe Off
Leg Lift
Swing
31
Q

Quadriceps femoris

34
Q

Leg lift muscles

A

Hamstrings
Anterior leg compartment
Iliopsoas, Rectus femoris

35
Q

Swing muscles

A

Iliopsoas and Rectus femoris
Quadriceps femoris
Anterior leg

36
Q

Which bone of the foot does no muscle originate from or insert into?

37
Q

How many bones are in the foot?

38
Q

The main joints of the foot

A

Ankle (talocrual)
Subtalar
Midtarsal

39
Q

40
Q

Mid foot =

A

Navicular + Cuboid + Cuneiforms

41
Q

Forefoot =

A

Metatarsals + Phalanges

42
Q

There are sesamoid bones in the foot. True or false?

43
Q

Where on the foot are there sesamoid bones?

A

1st metatarsal
