Anterior layer on thigh
pectineus, adductor longus, gracilis
middle layer
adductor brevis
posterior layer
adductor magnus
Obteratur nerve
go around brevis
pectineus
attaching from the pectineal line to the pectineal line of the femur
Inn: l234 and obturator
Action; adducts and aids in flexion
adductor longus
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
gracilis
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
Adductor brevis
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
Adductor magnus; rememeber the four openings and last one gives adducot hiatus
arises from the inferior pubic ramus and the ischial ramus and ichial tuberosity and inserts on linea aspera. Adducts and EXTENDS THE THIGH.
medial femoral circumflex
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
medial femoral circumflex
anastomoses with the ascending branch of the lateral femoral circumflex. MAIN blood supply
lateral femoral circumflex
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.
Descending branch of the lateral circumflex
gives branches to the quadricpes femoris and contributes to the collateral circulation around the knee joint.
Perforatin arteries
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.
descending genicular artery
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.
cruciate anastomosis
inferior gluteal, medial and lateral circumflex, and first perforating artery.
cutaneous innervation of the gluteal region
superior cluneal-lateral branches of l123, major sensory to the gluteal region
middle cluneal
lateral branches of dorsal rami of s1, s2, s3
inferior
branches of the posterior femoral cutaneous and ventral s123
iliohypogastic , lateral femoral cutaneous
l1 lateral cutaneous branch , l2l3
gluteus maximus
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
gluteus medius and minimus
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
Lateral rotaters of the thigh
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
Obterator internus
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
quadratus femoris
arises from the oschial tuberoisty and passes laterally to insert on the quadrate tubercle of the femur.
l4l5s1
obterator externus
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
throught the greater sciatic foramen
superior gluteal vessels and nerve, piriformis, sciatic nerve, posterior cutanoeus nerve of the thigh, nerve to the obterator internus, nerve to the quadrate femoris, pudendal nerve, internal pudendal vessels, inferior gluteal vessels and nerves
lesser foramen
tendon of the obterator internus, internal pudendal vessels, pudendal nerve, nerve to the obterator internus
superior gluteal
from internal illliac which leaves the pelvis superior to the piriformis, divides into a superficial and deep branch. Deep to the medius and medius with superior gluteal nerve. Superficial is to gluteus maximus
inferior gluteal
internal illiac and below piriformis, it supplies large branches to the gluteus maximus, cutanoeus branches and companion artery of the sciatic nerve.
extension of thigh
gluteus maximus, adductor magnus, the hamstrings
flexion of the thigh
illiospoas, tenosr fascia latae, sartorisu, rectus femoris, pectineus, all adductors.
abduction of the thigh
gluteus medius, gluteus minimus
adduction of the thigh
adductor longus, adductor brevis, adductor magnus, gracilis, pectineus

gluteus maximus, obt. ext and int, gamellis, piriformis, quadrate femoris, sartorius,
medial rotators,
glut min and med, tenosr fascia latae
gluteus maximus
from the sacroilliac joint and llliac crest to the gluteal tuberosity and illiotibial tract
medius and minimus
on greater trochanter
