In vertebrate anatomy, the hip, or coxa (pl.: coxae) in medical terminology, refers to either an anatomical region or a joint on the outer (lateral) side of the pelvis.. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and lateral to the obturator foramen, with muscle tendons and soft tissues overlying the greater trochanter of the femur.
Most modern anatomists define 17 of these muscles, although some additional muscles may sometimes be considered. These are often divided into four groups according to their orientation around the hip joint: the gluteal group; the lateral rotator group; the adductor group; and the iliopsoas group .
The hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty ) it is composed of three parts: the ilium , ischium , and the pubis .
Ilium (bone) Overview of Ilium as largest region of the pelvis. Capsule of hip-joint (distended). Posterior aspect. (Ilium labeled at top.) The ilium ( / ˈɪliəm /) ( pl.: ilia) is the uppermost and largest region of the coxal bone, and appears in most vertebrates including mammals and birds, but not bony fish.
The anterior superior iliac spine ( ASIS) is a bony projection of the iliac bone, and an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis. It provides attachment for the inguinal ligament, and the sartorius muscle. [1]
An attempt of a map the muscles in our list of skeletal muscles graphically based on location, showing variations and parts of the same muscle as well as number of standard occuranes in the human body
The iliacus arises from the iliac fossa on the interior side of the hip bone, and also from the region of the anterior inferior iliac spine (AIIS). It joins the psoas major to form the iliopsoas. It proceeds across the iliopubic eminence through the muscular lacuna to its insertion on the lesser trochanter of the femur.
The piriformis muscle is part of the lateral rotators of the hip, along with the quadratus femoris, gemellus inferior, gemellus superior, obturator externus, and obturator internus. The piriformis laterally rotates the femur with hip extension and abducts the femur with hip flexion.
Iliopsoas. Anterior hip and thigh muscles. The iliopsoas muscle ( / ˌɪlioʊˈsoʊ.əs /; from Latin: ile, lit. 'groin' and Ancient Greek: ψόᾱ, romanized : psóā, lit. 'muscles of the loins') refers to the joined psoas major and the iliacus muscles. The two muscles are separate in the abdomen, but usually merge in the thigh.
In human anatomy, a hamstring (/ ˈ h æ m s t r ɪ ŋ /) is any one of the three posterior thigh muscles between the hip and the knee (from medial to lateral: semimembranosus, semitendinosus and biceps femoris).
