NERVES OF THE LEG
|
NERVES OF THE LEG
|
|
|
SAPHENOUS
Origin |
Femoral Nerve
|
|
|
SAPHENOUS
Course |
Descends with femoral vessels through the femoral triangle and adductor canal
Then descends with the Great Saphenous Vein |
|
|
SAPHENOUS
Distribution |
Supplies skin on the medial side of the leg and foot.
|
|
|
SURAL
Origin |
Formed by the union of cutaneous branches from the tibial and common fibular nerves
|
|
|
SURAL
Course |
Descends between heads of the Gastrocnemius
Becomes superficial at the middle of the leg Descends with the Small Saphenous Vein Passes inferior to lateral malleolus to lateral side of foot |
|
|
SURAL
Distribution |
Supplies skin on posterior and lateral aspects of leg and lateral side of foot
|
|
|
TIBIAL
Origin |
Sciatic Nerve
|
|
|
TIBIAL
Course |
Forms as the Sciatic bifurcates at the apex of the Popliteal Fossa and lies on Popliteus
Runs inferiorly on Tibilais Posterior with the Tibial Vessels Terminates beneath the Flexor Retinaculum by dividing into medial and lateral plantar nerves |
|
|
TIBIAL
Distribution |
Supplies Posterior muscles of the leg and knee joint
|
|
|
COMMON FIBULAR NERVE
Origin |
Sciatic Nerve
|
|
|
COMMON FIBULAR NERVE
Course |
Forms as sciatic bifurcates at apex of Popliteal Fossa
Follows medial border of biceps femoris and it tendon Passes over posterior aspect of head of Fibula Goes deep to Fibualris Longus Divides into deep and superficial fibular nerves |
|
|
COMMON FIBULAR NERVE
Distribution |
Skin on lateral part of posterior aspect of leg
The lateral Sural Cutaneous Nerve The knee joint |
|
|
SUPERFICIAL FIBULAR
Origin |
Common Fibular Nerve
|
|
|
SUPERFICIAL FIBULAR
Course |
Arises between Fibularis Longusand neck of Fibula
Descends in the Lateral Compartment and dives deep to become subcutaneous in the distal third |
|
|
SUPERFICIAL FIBULAR
Distribution |
Anterior muscles of leg
Skin on distal third of anterio surface of leg and dorsum of foot Except skin of first interdigital cleft |
|
|
DEEP FIBULAR NERVE
Origin |
Common Fibular Nerve
|
|
|
DEEP FIBULAR NERVE
Course |
Arise between the Fibularis Longus and neck of the fibula
Passes thought the Extensor Digitorum Longus and descends on Interosseous Membrane Crosses distal end of Tibia and enters dorsum of the foot |
|
|
DEEP FIBULAR NERVE
Distribution |
Supplies anterior muscles of leg
Skin of first interdigital cleft Sens articular branches to join its crosses |
|
|
ARTERIES OF THE LEG
|
ARTERIES OF THE LEG
|
|
|
POPLITEAL ARTERY
Origin |
Continuation of the Femoral Artery at adductor hiatus in adductor magnus
|
|
|
POPLITEAL ARTERY
Course |
Passes through Popliteal Fossa to leg;
Ends at inferior border of Popliteus muscle by dividing into Anterior and Posterior Tibial Arteries |
|
|
POPLITEAL ARTERY
Distribution |
Superior, Middle and Inferior Genicular arteries to knee
Muscular branches to hamstrings and muscles of superficial posterior compartment of the leg |
|
|
ANTERIOR TIBIAL
Origin |
Popliteal Artery
|
|
|
ANTERIOR TIBIAL
Course |
Passes into Anterior Compartment thru gap in superior part of the interosseus membrane
Descends on the anterior interosseous membrane between Tibialis Anterior and Extensor Digitorum Longus |
|
|
ANTERIOR TIBIAL
Distribution |
Anterior Compartment of the leg
|
|
|
DORSALIS PEDIS (DORSAL ARTERY OF THE FOOT)
Origin |
Continuation of Anterior Tibial Artery distal to inferior Extensor Retinaculum
|
|
|
DORSALIS PEDIS (DORSAL ARTERY OF THE FOOT)
Course |
Descends anteromedially to first interosseous space;
Divides into deep plantar and 1st dorsal metatarsal arteries |
|
|
DORSALIS PEDIS (DORSAL ARTERY OF THE FOOT)
Distribution |
Muscles of the dorsum of the foot
Pierces interosseous muscle as deep plantar artery to contribute to formation of plantar arch |
|
|
POSTERIOR TIBIAL ARTERY
Origin |
Popliteal Artery
|
|
|
POSTERIOR TIBIAL ARTERY
Course |
