Arterial And Nerve Of Leg

Question 1

Anterior tibial artery passage

Answer 1

Passes between tibia and fibula and descends down the anterior compartment of the leg

Change his name to the dorsalis pedis artery when it reaches the dorsum of the foot

Question 2

Posterior tibial artery

Answer 2

Descends short way, and gives off the peroneal artery which descends the lateral aspect of the posterior compartment and supplies, posterior and lateral compartment of the leg

descends down the posterior compartment, passing posterior to the medial malleolus and divides into the medial and lateral plantar arteries

Question 3

Cutaneous nerve supply in the leg

Answer 3

Saphenous
Sural
Superficial peroneal
Deep peroneal

Question 4

Saphenous

Answer 4

Supplies skin on the medial side of the leg and foot

Originates from the femoral nerve, and descends through the adductor canal

Question 5

Sural

Answer 5

Originates from tibial in common peroneal nerve

Supplies the skin of the posterior and lateral aspect of the leg and foot

Question 6

Superficial peroneal

Answer 6

Skin on the distal third of the anterior surface of the leg and dorsum of the foot

Question 7

Deep peroneal

Answer 7

Skin of the first interdigit space

Question 8

Deep peroneal nerve (motor)

Answer 8

Supplies muscular innervation to the anterior compartment of the leg

It runs with the anterior tibial artery and ends with branches, innervating the ankle joints and skin between the first and second digits

Question 9

Tibial nerve (motor)

Answer 9

Travels with the posterior tibial artery down the back of the leg and passes posterior to the medial malleolus and divides into medial and lateral plantar nerves in the sole of the foot

Question 10

Superficial peroneal (motor)

Answer 10

Supplies innervation to the muscles of the lateral compartment of the leg

Innervates the skin along the distal aspect of the anterior surface of the leg, dorsum of the foot and digits 3 to 5
