17
Q

What innervates the lumbricals?

A

Medial One: medial plantar nerve

Lateral Three: lateral plantar nerve

18
Q

What is the main action of the lumbricals?

A

Flexes proximal phalanges at MTP joint

Extends phalanges at PIP and DIP joints

19
Q

What innervates the plantar interossei (3 muscles)?

A

Lateral plantar nerve

20
Q

What is the main action of the plantar interossei (3 muscles)?

A

Adducts digits 2-4

Flex metatarsophalangeal joint and extend phalanges

21
Q

What innervates the quadratus plantae?

A

Lateral plantar nerve

22
Q

What is the main action of the quadratus plantae?

A

Corrects for oblique pull of flexor digitorum longus tendon, thus assists in flexion of toes

23
Q

Arterial supply to the foot is delivered via two arteries:

A

Dorsalis pedis (a continuation of the anterior tibial artery)

Posterior tibial

24
Q

Describe the course of the sciatic nerve and innervated muscles.

A

The sciatic splits in the popliteal fossa to form the:

Tibial nerve – the muscles of the posterior leg (calf muscles), and some of the intrinsic muscles of the foot.

Common fibular nerve – the muscles of the anterior leg, lateral leg, and the remaining intrinsic foot muscles.

25
Q

Describe the termination of the common fibular nerve.

A

The common fibular nerve terminates by dividing into the superficial fibular and deep fibular nerves

26
Q

Describe the termination of the tibial nerve.

A

The tibial nerve divides on the bottom of the foot into the medial and lateral plantar nerves.

27
Q

What nerves supply the dorsum of the foot?

A

The superficial fibular nerve (not toes)

The deep fibular nerve (1st and 2nd toes)

28
Q

What are the 3 muscle layers of the foot?

A

AFA

2Muscles 2Tendons

FAF

29
