4. SUPERFICIAL
FASCIA
CONTENT
 Superficial veins
 Cutaneous nerves
 Lymphatics
 Small unnamed arteries

5.  SUPERFICIAL VEINS :
 Dorsal venous arch :
 Lies on dorsum of foot
• Over proximal parts of metatarsal bones
 Great or long saphenous vein :
 Union of medial end of dorsal venous arch with
medial marginal vein
 Drains medial side of the great toe
 Small or short saphenous vein :
 Union of the lateral end of the dorsal venous arch
with the lateral marginal vein

6.  CUTANEOUS NERVES :
 Infrapatellar branch of the saphenous nerve :
• Pierces sartorius and deep fascia on medial side of knee
 Saphenous nerve :
• Branch of posterior division of femoral nerve
• Pierces deep fascia on medial side of knee between sartorius and gracilis
 Lateral cutaneous nerve of the calf :
• Branch of common peroneal nerve
• Pierces deep fascia over lateral head of gastrocnemius
 Superficial peroneal nerve :
• Branch of common peroneal nerve
• Arises : lateral side of neck of fibula deep to fibres of peroneus longus
• Descends : between peroneal muscles

7.  Superficial peroneal nerve :
• Branch of common peroneal nerve
• Arises : Lateral side of neck of fibula deep to fibres of peroneus longus
• Descends : Between peroneal muscles
• Supply :
o Skin over lower one-third of lateral side of leg
o Skin over entire dorsum of foot with exception
 Lateral border - Supplied by sural nerve.
 Medial border up to base of great toe - Supplied by saphenous nerve
 Cleft between first and second toes - Supplied by deep peroneal nerve
 Distal phalanges including nail beds of 1- 5 toes
 Sural nerve :
• Branch of tibial nerve
• Arises : Middle of popliteal fossa
• Runs vertically downwards

8.  Deep peroneal nerve :
• Terminates by supplying skin
• Adjoining cleft between first and second toes
 Digital branches of medial and lateral plantar nerves :
• Curve upwards and supply distal parts of dorsum of toes
• Medial plantar nerve supplies : Medial 3½ toes
• Lateral plantar nerve supplies : Lateral 1½ toes

9. DEEP
FASCIA
 Deep facia surrounds leg
and its continuous above
with deep fascia of thigh
 Below tibial condyles it
attached to periosteum on
anterior and medial boarder
of tibia
 Intermuscular septa divide
the leg into
3 compartments
• Anterior
• Posterior
• Lateral
