CROSS SECTION

Question 1

found in the cutaneous layer?

Answer 1

the skin

Question 2

the bones?

Answer 2

tibia

fibula

Question 3

superficial fascia?

Answer 3

great saphenous vein
small saphenous vein
saphenous nerve
medial sural cutaneous n/sural nerve
sural communicating n
lateral cutaneous n of the calf

Question 4

deep fascia?

Answer 4

anterior crural inter muscular septum
posterior crural inter muscular septum
deep transverse intermuscular septum

Question 5

what is found in the cross section of the leg?

Answer 5

cutaneous layer
bones
superficial fascia
deep fascia
interosseous membrane
anterior compartment
lateral compartment 
posterior compartment
-deep
-superficial

Question 6

the medial bone, roughly triangular at this level on cross section

Answer 6

tibia

Question 7

the lateral bone

Answer 7

fibula

Question 8

name this structure

at the medial side, near the medial border of the tibia

Answer 8

great saphenous v

Question 9

name this structure

main branch at the medial side, near the great saphenous vein

small branches along the medial 1/2 of the leg

Answer 9

saphenous nerve

Question 10

name this structure

at the posterior aspect and usually just lateral to the midline

Answer 10

small saphenous vein

Question 11

name this structure

at the posterior aspect, near the small saphenous vein

Answer 11

medial sural cutaneous nerve or sural nerve

Question 12

name this structure

at the lateral aspect

often only small branches at this level as the nerve exits the deep fascia more proximally

Answer 12

lateral cutaneous nerve of the calf

Question 13

at the posterior lateral aspect

it passes in an inferomedial direction toward the sural nerve

Answer 13

sural communicating nerve

Question 14

name this fascia:

thicker anteriorly because some muscles take partial origin from the fascia

Answer 14

deep fascia/fascia cruris

Question 15

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

Answer 15

Anterior Crural Intermuscular Septum / Anterior Fascial Septum of the Leg

Question 16

name this structure of the deep fascia

• an extension of the fascia cruris from its lateral aspect which passes to the posterior border of the fibular shaft (extends the length of the fibula)
• separates the lateral crural compartment from the posterior crural compartment

Answer 16

Posterior Crural Intermuscular Septum / Posterior Fascial Septum of the Leg

Question 17

name this structure of the deep fascia

• an extension of the fascia cruris from posteromedial to posterolateral near the
  posterior crural intermuscular septum; deep to soleus muscle
• attaches to the medial tibial border, the tibial soleal line, the crista medialis, the
  posterior border of the fibular shaft, and the distal posterior tibiofibular ligament
• separates the superficial posterior crural compartment from the deep posterior crural compartment
• usually covers the posterior surface of the tibial nerve and posterior tibial artery

Answer 17

Deep Transverse Crural Intermuscular Septum /

Deep Transverse Fascial Septum of the Leg

Question 18

name this structure of the deep fascia

• a sheet of fibrous tissue connecting the tibia and fibula at their interosseous borders
• fibers pass from superior medial to inferior lateral which allows the fibula to
  glide slightly proximal with respect to the tibia
• a superior opening pierces the membrane at the level of the neck of the fibula;
  allows passage of the anterior tibial artery
• an inferior opening pierces the membrane near the tibiofibular syndesmosis;
  allows passage of the perforating fibular artery

Answer 18

Interosseous Membrane
