16

What is the pathway of the saphenous nerve and what does it supply?

It is a terminal branch of the femoral nerve
begins at the adductor canal
passes between tendons of gracilis and sartorious
passes anterior to medial malleolus then over the dorsum of the foot
It supplies articular branches to the ankle joint and skin of the anteromedial shin, the medial side of the ankle and foot up until the head of the 1st metatarsal

17

Which toe is the reference point for abduction and adduction of the toes?

The second digit

18

What actions occur at the plantar and dorsal interossei?

Plantar adduct (PAD)
Dorsal abduct (DAB)
(small amounts of flexion occur at both)

19

What does the superficial fibula nerve divide into?

medial and intermediate dorsal cutaneous nerves

20

Whatt skin does the superficial fibula nerve supply?

skin over the dorsum of the foot
skin over the dorsal medial half of the big toe
skin over the lateral 3 and a half digits

21

What forms sinus tarsi?

Calcanues and Talus

22

Where does the deep fibula nerve run and what does it supply?

Passes deep to the extensor retinaculum, between extensor hallucis longus and extensor digitorum longus

Emerges between the 1st and 2nd digits

supplies Extensor hallucis brevis and Extensor digitorum brevis
supplies the tarsal and tarsometatarsal joints
supplies skin between the 1st and 2nd digits

23

Medial and lateral plantar nerves
common plantar digital nerves
proper plantar digital nerves

24

What runs through the adductor canal?

nerve to vastus medialis
Femoral artery
Femoral nerve
saphenous nerve

25

What is the adductor canal?

an intermuscular passageway through the medial thigh. It starts at the apex of the femoral triangle and finishes at the adductor hiatus

26

What structures that run through the adductor canal continue through the adductor hiatus?

Femoral artery
Femoral vein

27

What is the popliteal fossa?

A diamond shaped space on the posterior aspect of the knee that allows passageway of neurovascular structures between the thigh and the leg.

28

What is the pathway of the medial plantar nerve? and what does it supply?

It is the larger and more anterior branch of the tibial nerve

Enters the sole of the foot, passing deep to abductor hallucis between layers 1 and 2
Runs between abductor hallucis and flexor digitorum brevis

Terminates as sensory branches as common and proper digital nerves

plantar aspect of the joints of the foot

32

What is the pathway of the lateral plantar nerve?

Passes deep to abductor hallucis
Runs between the 1st and 2nd layers of muscles with the lateral plantar artery
