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
Which toe is the reference point for abduction and adduction of the toes?
The second digit
What actions occur at the plantar and dorsal interossei?
Plantar adduct (PAD) Dorsal abduct (DAB) (small amounts of flexion occur at both)
What does the superficial fibula nerve divide into?
medial and intermediate dorsal cutaneous nerves
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
What forms sinus tarsi?
Calcanues and Talus
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
What are the branches of the tibial nerve?
Medial and lateral plantar nerves
common plantar digital nerves
proper plantar digital nerves
What runs through the adductor canal?
nerve to vastus medialis
Femoral artery
Femoral nerve
saphenous nerve
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
What structures that run through the adductor canal continue through the adductor hiatus?
Femoral artery
Femoral vein
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.
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
What muscles does the medial plantar nerve supply?
abductor hallucis
Flexor digitorum brevis
Flexor hallucis brevis
1st lumbrical
What makes up the pes anserine and what is there nerve supply?
SGT FOT!
Sartorious (femoral nerve)
Gracilis (Obturator nerve)
Semintendinosis (Tibial nerve)
What is the cutaneous supply from the medial plantar nerve?
medial 3 and a half digits
skin over the medial and central aspects of the sole of the foot
plantar aspect of the joints of the foot
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
divides at the lateral compartment of the foot into superficial and deep branches
What does the lateral plantar nerve supply?
All muscles in the plantar plantar surface of the foot, not supplied by the medial nerve
joints of the foot
skin of lateral 1 and a half digits and lateral sole
What structures pass under the flexor retinaculum of the foot?
Tom Dick And Very Naughty Harry!!! Tibialis posterior flexor Digitorum longus posterior tibial Artery osterior tibial Vein tibial Nerve flexor Hallucis longus
What are the two Sural nerves? What nerve do they come from? What structure do they run with? And what does it supply?
The two sural nerves are the lateral and medial sural nerves.
The medial sural nerve comes from the tibial nerve
The lateral sural nerves comes from the common fibular nerve
It accompanies the small saphenous vein
it supplies skin on the lateral aspect of the foot and the ankle joint
What is the dorsalis pedis artery a continuation of?
The anterior tibial artery
What is the pathway of the dorsalis pedis artery?
Passes deep to inferior extensor retinaculum
passes between tendons of EHL and EDL
at the 1st metatarsal it divides into 1st dorsal metatarsal artery and deep plantar artery
What are the branches of the dorsalis pedis artery?
Lateral tarsal artery
arcuate artery
deep plantar artery
1st dorsal metatarsal artery
What are the plantar arteries of the foot?
