12
Q

What are the functions of the arches of the foot?

A

provide shock absorption; push off spring and increased weight bearing capacity by weight redistribution

13
Q

What supports the arches of the foot?

A

plantar aponeurosis and the plantar ligaments

14
Q

What is the plantar aponeurosis?

A

a thickened central area of plantar fascia- the feep fasica of the sole of the foot

calcaneus; talus; navicular; 3 cuneiforms and metatarsals 1-3

17
Q

What is the medial longitudinal arch supported by?

A

the flexor hallucis longus and the attachments of tibilais anterior and fibularis longus

18
Q

What is the attachment of tibilais anterior?

A

junction between the medial cuneiform and base of 1st metatarsal

19
Q

What is the attachment of fibularis longus?

A

tendon passses acorss the plantar aspect of hte bones of the foot from lateral to medial to also attach to the medial cuneiform and base of the 1st metatarsal

20

attach proximally and distally within the foot

24
Q

Where are the intrinsic muslces of the foot mainly located?

A

compartments within the sole where they are arranged in 3 layers
