Without hip muscles there is no way the hip could move. It is for this reason that the muscles around the hip joint are very important. Normally there are 17 muscles around the hip but they have been divided into different groups depending with the way the muscles have been arranged. The different groups are the adductor group, gluteal group, and the iliopsoas group, the lateral rotator group.Credit: http://champsforcharity.blogspot.com/2012/04/muscle-group-of-month-abductors-and.html
Abductor group of Hip Muscles
They include adductor longus, adductor brevis , pectineus, gracilis and adductor magnus which when combined makes up the abductor group. All the abductors originate from the pubis inserting in the medial which is posterior to the femur. The only exception is the gracilis which inserts below the medial condyle.Credit: http://makaayo.blogspot.com/2011/06/how-to-build-better-butt.html
Gluteal muscles of Hip Muscles
These muscles include the tensor fasciae latae, gluteus medius, gluteus minimus and gluteus maximus. Gluteus maximus forms most of the muscles of the buttocks and originate from the ilium and on the sacrum and inserts on the iliotibial tract as well as the gluteal tuberosity on the femur. Gluteus minimus and the gluteus medius both originate from the ilium anteriorly to the gluteus maximus. Both the gluteus minimus and the gluteus medius insert on the greater trochanter on the femur. Tensor fasciae latae shares its origin and the insertion point with the gluteus maximus.Credit: http://www.squidoo.com/psoas
Iliopsoas and Rotator Group Hip muscles
The psoas major and the iliacus form the iliopsoas group. The psoas major is a large muscle that runs from the transverse processes of the L5 to L1 vertebrae. The psoas major joins with the iliacus through the tendon connecting to the lesser trochanter on the femur. The origin of the iliacus is the iliac fossa on the ilium.Credit: http://www.aikidonorthgeorgia.org/tags/patients/
Lateral Group of rotator muscles
This group is made up of these muscles; internus obturators, the piriformis, externus the superior, and the quadratus femoris and inferior gemelli. All these muscles originate from the acetabulum of the ilium and insert on the greater trochanter on the femur. Apart from the muscles mentioned above, there are some other muscles which are known to contribute effectively in the movement of the hip. One of the extra muscles is the sartorius and the rectus femoris. Mostly these muscles are left out because they are involved with the movement of the knee.
All the hip muscles surround the hip joints from all directions and work in collaboration with each other to ensure that they are consistent in the movement of the hip. They have a complementary system whereby if one hip muscle contract, the one on the other side relaxes. This is most common in those people who attempt to push their muscles before they completely heal from an injury.
It is known that the hip muscles help in four different types of movements of the hip. One of the common movements is the rotation forward and back. This will happen when one runs or walks. Your hip muscles must rotate for you to be able to make any progress. One of the hips takes the next step while the other hip bears the weight of the body so that you do not fall. Even when a person is standing still the hip muscles still rotate. The other movement takes place when a person bends his torso back or forth. The other movement of the hip muscles occurs when one bends from side to side.
