medial malleous of tibia and fibula

Answer 28

prominence of the inner side of the ankle, formed by the lower end of the tibia

Question 29

lateral malleous of tibia and fibula

Answer 29

Question 30

anterior of the thigh

Answer 30

femoral nerve (L2-L4)

posterior of the leg

Answer 34

tibial nerve

Question 35

lateral of the leg

Answer 35

superficial fibular nerve

Question 36

lumbosacral plexus

Answer 36

formed by the anterior divisions of the lumbar nerves, sacral nerves, and coccygeal nerves to supply the lower limbs

Question 37

femoral nerve

Answer 37

largest branch of the lumbar plexus; comes out from the intervertebral foramen to make way from the pelvis to innervate the anterior compartment of the thigh (L2-L4)

Question 38

obturator nerve

Answer 38

passes out from pelvis from the obturator foramen to innervate the medial compartment of the thigh (L2-L4)

Question 39

sciatic nerve

Answer 39

innervates the posterior compartment of the thigh from the greater sciatic foramen of the gluteal region (L4-S3)

Question 40

the sciatic nerve splits into the...

Answer 40

tibial nerve and common fibular nerve to supply the leg

Question 41

tibial nerve

Answer 41

sciatic nerve continues as the tibial nerve in the posterior compartment of the leg, innervates the muscles of that compartment

Question 42

fibular nerve

Answer 42

branches off of the sciatic nerve and wraps around the neck of the fibula to split into the superficial and deep branches

Question 43

superficial fibular nerve

Answer 43

innervates later compartments of the leg

Question 44

deep fibular nerve

Answer 44

innervates the anterior compartment of the leg
