|
Abductor digit minimi (lateral plantar n)
Flexor digitorum brevis (medial plantar n) Abductor hallucis (medial plantar n) |
|
|
what is found in layer 2 of the plantar foot muscles? what nerves act on these muscles?
|
this contains
Quadratus plantae (lateral plantar n) The lumbricals (1st- medial plantar n, 2,3,4-lateral plantar n) these attach to the FDL tendons and run to the extensor expansion also FDL and FHL tendons are found in layer 2 |

adductor hallucis (lateral n) 2 heads flexor hallucis brevis (medial plantar n) |
|
|
what is found in layer 4 of the plantar foot? what nerves act on stuff?
|
the plantar interossei (PAD...lateral plantar n) digits 3-5/ flex MTP
the dorsal interossei (DAB..lateral plantar n) digits 2-4/ flex MTP |
|
|
What does the medial plantar nerve innervate? where does it come from?
|
This comes from the tibial nerve
this innervates 1st lumbricles, FHB, FDB, AbH also the sensory to the medial sole, 3 and 1/2 medial digits |
|
|
What does the lateral plantar nerve innervate? where does it come from?
|
this innervates the 2,3,4th lumbricles
adductor hallicus flexor digit minimi brevis quadratus plantae abductor digit minimi |
|
|
What nerves provide sensory to the plantar portion of the digits?
|
the common plantar digital nerves which then branch into the proper plantar digital nerves
|
|
|
where does the saphenous nerve come from? where does it provide sensory?
|
this comes from the femoral nerve
provides sensory to the medial foot |
|
|
where does the sural nerve come from?
where does it provide sensory to? |
this comes from the femoral nerve
provides sensory to the lateral foot |
|
|
what provides sensory to the heal?
|
tibial nerve (calcaneal branches)
|
|
|
what does the plantar reflex test?
|
L4-S2
done by stroking lateral foot |

|
|
where does the deep plantar artery come from?
|
this comes from the dorsalis pedis, which comes from the anterior tibial artery
|
|
|
where does the medial venous flow go?
|
this goes to the medial marginal vein...then to the great saphenous vei
|
|
|
where does the lateral venous flow go?
|
this goes to the lateral marginal vein, then to the small saphenous vein
|
|
|
where does superficial medial lymph flow go?
|
this follows great saphenous vein, to the superficial inguinal nodes
