The hip muscles encompass countless muscles of the hip and also thigh who main function is to act on the thigh at the i know well joint and also stabilize the pelvis. There is no them, walking would be impossible. They can be split into three main groups:

Iliopsoas groupHip adductors

This post will present the muscle in every group and also touch on their origin, insertion, function, and innervation.

Key facts around hip muscles
Iliopsoas groupMuscles: iliacus, psoas major, and psoas minorMain function: flexion that the trunk and thigh, lateral flexion of the stems (excluding psoas significant and minor only)Innervation: anterior rami the spinal nerves L1-L3 and femoral nerve (L2-L4) (iliacus only)
Gluteal muscles (superficial)Muscles: gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae lataeMain function: differed – extension, external and also internal rotation, abduction and adduction of the thighInnervation: premium (L4, S1) and also inferior (L5-S2) gluteal nerves
Gluteal muscles(deep)Muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, obturator externus, and also quadratus femorisMain function: exterior rotation and abduction the the thigh; stabilizes head of femurInnervation: differed – nerve come piriformis (S1-S2), nerve to obturator internus (L5-S2), nerve to quadratus femoris (L4-S1), obturator nerve (L3-L4)
Hip adductorsMuscles: Gracilis, pectineus, adductor longus, adductor brevis, adductor magnus, and adductor minimusMain function: Adduction of the thigh at the i know well jointInnervation: Obturator nerve (L2-L4) and femoral nerve (L2-L3) (pectineus only)
Clinical pointsFemoral triangle

as you deserve to see, over there are plenty of hip muscles. Start by learning to determine the muscle of the hip and thigh with this study unit.

Iliopsoas group

The iliopsoas group of muscles coins its surname from the muscles that make that up: iliacus, psoas major, and also psoas minor. Castle lie in the iliopsoas compartment in the posterior abdomen together with the lumbar plexus. The iliopsoas muscles originate native the posterior abdominal wall and insert at the lesser trochanter the the femur.


all iliopsoas group muscles overcome the hip joint and share the very same functions:

Flexion that the trunk and thigh exterior rotation the the thigh

In addition, the psoas significant and psoas boy laterally flex the trunk.

Iliacus

Iliacus is a large triangular shaped muscle the lies end the surface of the ilium, lateral come the lower component of the psoas major and psoas boy muscles. Its yarn merge v fibers of the psoas major muscle roughly the level that the inguinal ligament to come to be the iliopsoas muscle – the main flexor that the thigh. Iliacus receives its innervation native the femoral nerve (L2-L4) and also functions come flex the trunk and also hip and also externally turn the thigh.
