Saphenous Artery, Vein, and Nerve • Artery –Takes blood from heart to lower leg and foot • Vein –Takes blood to heart from lower leg and foot • Nerve –Sends and receives impulses to lower leg and foot * A Branch of the Femoral = Saphenous A,V,N = Sartorius
Obturator Nerve • Sends and Receives Impulses to medial thigh (Gracilis) *The left leg is tilted (Picture taken from side)
Vastus Lateralis – Expose • O: Femur I: Tibia P: Extends Leg *Cat horizontal- picture taken from side * Rectus Femoris Transected
Vastus Intermedius – Expose • O: Femur I: Tibia P: Extends Leg *Cat horizontal- picture taken from side * Rectus Femoris Transected
Vastus Medialis – Expose • O: Femur I: Tibia P: Extends Leg *Cat vertical as in example ^ *Cat horizontal- picture taken from side* Rectus Femoris Transected
Lateral Circumflex Femoral A,V = Rect. Fem. = LCF A,V • Artery –Takes blood from heart to quadriceps femoris muscle mass • Vein –Takes blood to heart from quadriceps femoris muscle mass * A Branch of the Femoral
Adductor Longus and Femoris -Expose • Longus - O: Pubis I: Femur P: Adduct the Thigh • Femoris -O: Pubis and Ischium I: Linea Aspera P: Adduct the Thigh
Deep Femoral Artery and Vein • Artery –Takes blood from heart to adductors • Vein –Takes blood to heart from adductors * A Branch of the Femoral This blood vessel, deep to the adductors, can be found between the Adductor Longus and the Vastus Medialis.
Semimembranosus, Semitendinosus -Expose • Semimem. - O: Ischium I: Medial aspect of Tibia P: Flex the Leg • Semitend. -O: Ischium I: Medial aspect of Tibia P: Flex the Leg
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
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
Capsule Cavity • In the knee; houses the quadriceps tendon, synovial membrane, crossed ligaments, and semilunar cartilage.
