adductor longus

Back 6

innervation: obturator nerve (l234)
arises from the body of the pubic bone and expands into a broad fleshy belly and inserts via an aponeurosis into the middle third of the linea aspera.
Adducts the thigh, assists in flexion

Front 7

gracilis

Back 7

most superficial muslce on the medial side of the thigh. Arises from the pubic ramus and is inderted into the upper part of the medial surface of the body of the tibia. Obturator nerve innervation. Adducts the thigh, flexes the leg at the knee joint

Front 8

Adductor brevis

Back 8

is situated immediately posterior to the pectineus and adductor longus muscles . Triangular. Superior attachemtns include body and inferior ramus of the pubis. inferiorly to the proximal thrid of the linea aspera. Obterator and adducts and assists in flexion

Front 9

Adductor magnus; rememeber the four openings and last one gives adducot hiatus

Back 9

arises from the inferior pubic ramus and the ischial ramus and ichial tuberosity and inserts on linea aspera. Adducts and EXTENDS THE THIGH.

Front 10

medial femoral circumflex

Back 10

arises from the posterior aspect of the profunda and courses laterally arounf the iliopsoas tendon (after going between pectineus and iliopsoas immediately) and courses to the neck of the femur

Front 11

medial femoral circumflex

Back 11

anastomoses with the ascending branch of the lateral femoral circumflex. MAIN blood supply

Front 12

lateral femoral circumflex

Back 12

arises from the lateral side of the profunda and divides into ascending, transverse, and descending branches. The ascending branches ascend along the intertrochnateric line of the femur and supplies the hip joint and the adjacent muscles. The transverse branch is small and anast with arteries at the back of the femur.

Front 13

Descending branch of the lateral circumflex

Back 13

gives branches to the quadricpes femoris and contributes to the collateral circulation around the knee joint.

Front 14

Perforatin arteries

Back 14

are usually 4 in number and are so named because they perforate the adducto magnus. Form an important anastomosis in the posterior aspect of the thigh.

Front 15

descending genicular artery

Back 15

arises from the femoral just before it passes through the opening in the tenon of the adductor magnus, and it immediately divides into a saphenous and articular branch. the saphenous branch accompanies the saphenous nerve to the medial side of the knee. The articluar branch supplies branches around the knee.

Front 21

gluteus maximus

Back 21

acts to straighten the lower limb and is chief extensor of the thigh at hip joint. Is capable of laterally rotating the thigh.
Inn. INferior gluteal
superior and inferior gluteal arteries

Front 22

gluteus medius and minimus

Back 22

gluteus medius and minimus are abductors and medial rotators of the thigh and are also used, when one foot is raised, to prevent the pelvis from tilting towards the side of the raised foot during the walking cylce. Produces trendelenburg sign. INN is superior gluteal and superior gluteal artery

Front 23

Lateral rotaters of the thigh

Back 23

piriformis arises from within the pelvis from anterio lateral surface of the saccrun. It then passes from the pelvis into the glutel region through the greater sciatic foramen and inserts onto the superior surface of the greater trochanter. s1s2

Front 24

Obterator internus

Back 24

from within the pelvis (1) the bony perimeter of the obterator foramen and the obterator membrane. The tendon passes from the pelvis to the gluteal region though the lesser sciatic foramen and inserts on the medial surface of the greater trochanter near its base. inn is l5, s1, s2

Front 25

quadratus femoris

Back 25

arises from the oschial tuberoisty and passes laterally to insert on the quadrate tubercle of the femur.
l4l5s1

Front 26

obterator externus

Back 26

arises from the external surface of the bony boundary of the obterator foramen and membrane. The tendon runs across the posterior surface of the neck of the femur and inserts into the trochanteric fossa. l2, l3, l4

Back 29

Back 30

internal illiac and below piriformis, it supplies large branches to the gluteus maximus, cutanoeus branches and companion artery of the sciatic nerve.
