adductors, can be found between
the Adductor Longus and the
Vastus Medialis.

Freed
Transected
Sciatic Nerve

Sends and receives
impulses to the
posterior muscles of
the thigh (Biceps
Femoris)
Popliteal Artery and Vein

Artery – Takes blood from
heart to the back of the knee

Vein – Takes blood to heart
from back of the knee
*Branches off of the Deep
Femoral
Gluteus Medius, Gluteus Maximus 

Medius - O: Ilium I: Femur P: Abduct Thigh
Maximus. - O: Sacral Vertebrae I: Femur P: Abduct Thigh
Gluteus Max

Peroneus Tertius

O: Fibula I: Phalanges P: Extends Foot
Peroneus Longus

O: Fibula I: Metatarsals P: Pronates Foot
Peroneal Nerve
The Peroneal Nerve sends and receives
impulses to the anterior and lateral lower
leg muscles (shin area).
It is a branch of the Sciatic Nerve
Tibialis Anterior

O: Tibia I: Phalanges P: Flex Foot
Extensor Digitorum Longus

O: Femur I: Phalanges P: Extends the Toes
Capsule Cavity
In the knee; houses the quadriceps tendon, synovial
membrane, crossed ligaments, and semilunar cartilage.
