Lower Limb Anatomy
superficial fibular nerve
L4-S2 branches off common fibular nerve
tibial nerve
L4-S3
common fibular nerve
Level L4-S4
sciatic nerve
Level L4-S4 innervates all muscles of the posterior thigh
lateral condyle
Located on outside part of knee Bigger than medial condyle
metarsal bones
foot bones 5 metatarsal bones
calcaneus
heel bone
femoral nerve
inntervates muscles of anterior compartment Level L2-L4
patella
large sesamoid bone forms the kneecap
profunda femoris artery
largest branch of femoral artery
piriformis
laterally rotates and abducts thigh
obturator internus
laterally rotates thigh
obturator nerve
level L2-L4
linea aspera femur
line going down femur
great saphenous vein
longest vein in body originate at dorsal venous arch drains into femoral vein
femoral vein
major vein of the thigh that receives blood from the deep femoral and great saphenous vein
lateral malleolus
process forming the outer ankle
Greater & lesser trochanter
sites for muscle attachment
dorsalis pedis artery
supplies blood to foot
fibular artery
supplies blood to lateral compartment of leg
posterior tibial artery
supplies blood to posterior compartment of leg
anterior tibial artery
supplies blood to the anterior compartment of leg
inferior gluteal artery
supplies gluteus maximus
femoral artery
the major artery supplying the leg
tibial plateau
the top, flat portion of the tibia
Femur
- Strongest bone in body - transmit weight from hip bone to tibia
tarsal bones
- the seven bones of the ankle
sesamoid bones
Allow for increased weight-bearing & leverage Look like little nuts on the toe & finger bones
popliteal artery
Artery that supplies blood to the foot
medial epicondyle
Bigger than lateral epicondyle Attachment site for ligaments of the knee
superior gluteal artery
Blood supply of gluteus medius
tibia
Much bigger than the fibula Medial long bone of leg shin bone
fibula
Much smaller than the tibia Lateral bone of the leg calf bone
medial condyle
Sits on top of tibia to form the tibiofemoral joint Located on inside part of the knee
lateral epicondyle
Smaller than medial epicondyle Attachment site for ligaments of the knee
head of femur
The head always points toward what side it is on So if head points right, then its a right femur Allows for motion in the hip Ball shaped
talus
ankle bone
tibial tuberosity
attachment site for patellar ligament
phalanges
bones of the fingers and toes big toe or thumb only has a proximal and distal phalanx (the rest have proximal, middle, and distal)
Deep fibular nerve
branches off common fibular nerve L4-S2
posterior tibial vein
drain posterior compartment of leg, ankle, and foot
popliteal vein
drains blood into femoral vein
