CROSS SECTION Flashcards
found in the cutaneous layer?
the skin
the bones?
tibia
fibula
superficial fascia?
great saphenous vein small saphenous vein saphenous nerve medial sural cutaneous n/sural nerve sural communicating n lateral cutaneous n of the calf
deep fascia?
anterior crural inter muscular septum
posterior crural inter muscular septum
deep transverse intermuscular septum
what is found in the cross section of the leg?
cutaneous layer bones superficial fascia deep fascia interosseous membrane anterior compartment lateral compartment posterior compartment -deep -superficial
the medial bone, roughly triangular at this level on cross section
tibia
the lateral bone
fibula
name this structure
at the medial side, near the medial border of the tibia
great saphenous v
name this structure
main branch at the medial side, near the great saphenous vein
small branches along the medial 1/2 of the leg
saphenous nerve
name this structure
at the posterior aspect and usually just lateral to the midline
small saphenous vein
name this structure
at the posterior aspect, near the small saphenous vein
medial sural cutaneous nerve or sural nerve
name this structure
at the lateral aspect
often only small branches at this level as the nerve exits the deep fascia more proximally
lateral cutaneous nerve of the calf
at the posterior lateral aspect
it passes in an inferomedial direction toward the sural nerve
sural communicating nerve
name this fascia:
thicker anteriorly because some muscles take partial origin from the fascia
deep fascia/fascia cruris
name this structure of the deep fascia
- an extension of the fascia cruris from its anterolateral aspect which passes to
the anterior border of the fibular shaft (extends the length of the fibula) - separates the anterior crural compartment from the lateral crural compartment
