Q

What are the roles of the muscles in the sole of the foot?

A

help maintain foot arches

stand on uneven ground

20
Q

What three short muscles extend from the calcaneus to phalanges?

A

The first layer of muscles

abductor digiti minimi
flexor digitorum brevis
abductor hallucis

21
Q

What muscle joints the tendon of FDL to calcanus?

A

quadratus plantae.

It also assists FDL in flexing lateral four digits.

22
Q

What muscles flex the MP joints?

A

lumbricals.

They also extend PIP and DIP joints.

23
Q

What are the plantar muscles?

A

flexor digiti minimi brevis

adductor hallucis

flexor hallucis brevis

24
Q

What muscle protects the first metatarsal head and tendon of FHL when standing and walking?

A

flexor hallucis brevis

25
Q

The fibularis longus and tibialis posterior tendons are found in what layer of plantar muscles?

A

The fourth layer

26
Q

What tendons are found in the fourth layer (planta muscles)?

A

fibularis longus and tibialis posterior tendons

27
Q

What is hallux valgus characterized by?

A

Lateral deviation of the great toe.

28
Q

What is a mallet toe?

A

flexion in the distal IP joint

29
Q

what is a hammer toe?

A

extension at the MP joint and flexion at the proximal IP joint.

30
Q

What is a claw toe?

A

extension at the MP joint and flexion at both the proximal and distal IP joint.

31
Q

What is a trigger toe?

A

A deformity that occurs at the MP/IP joints in the large toe.

32
Q

What do toe deformities appear as a result of?

A

Shortened flexor muscles which override lumbrical function.

33
Q

The tibial nerve divides the posaterior to medial malleous into what nerves?

A

medial and lateral plantar nerves

34
Q

What do the medial and lateral plantar nerves supply?

A

All intrinsic muscles of the foot

plantar skin

They appear in the second foot layer

35
Q

What is the larger of the two terminal branches of the tibial nerve?

A

Medial plantar nerve

36
Q

WHat muscles does the medial plantar nerve supply?

A

abductor hallucis

flexor digitorum brevis

most medial lumbrical

flexor hallucis brevis

37
Q

What is the smaller of the two terminal branches of the tibial nerve?

A

lateral plantar nerve

38
Q

Wht muscles do the lateral plantar nerve innervate?

A

abductor digiti minimi

quadratus plantae

lateral three lumbricals

adductor hallucis

fdmb

interossei

39
Q

What arteries supply the foot?

A

Terminal branches of the anterior and posterior tibial arteries.

40
Q

What are two branches of the dorsalis pedis artery?

A

Arcuate artery

deep plantar artery

41
Q

What two divisions of the posterior tibial artery supply the sole of the foot?

A

medial and lateral plantar arteries

42
Q

What are the functions of foot arches?

A

absorb shock during weightbearing

makes foot adaptable to surface and weight changes

43
Q

What are the two foot arches?

A

Longitudinal arch

transverse arch

44
Q

What forms the transverse arch?

A

cuboid, three cuneiforms and metatarsal bases

45
Q

What does the talus (ankle bone) articulate with?

A

superiorly = two leg bones

inferiorly = calcaneus

anteriorly = navicular bone
