1/7 Synonyms: Anal cleft, Crena ani The intergluteal cleft is a surface anatomy landmark of the pelvis and lower limb. It is the deep furrow or groove that lies between the two gluteal regions (commonly known as the buttocks). It extends from sacral level S3 or S4 and ends just inferior to the apex of the sacrum, at the level of the anus. The buttocks ( SG: buttock) are two rounded portions of the exterior anatomy of most mammals, located on the posterior of the pelvic region. In humans, the buttocks are located between the lower back and the perineum.

Bone Structure Muscles Subcutaneous Fat Skin Let's take a look at each of these in turn. Bone Structure The pelvis is the part of your skeleton which forms the shape of your hips and basis for your buttocks. This is one part of your butt that you cannot change. The gluteal muscles, also referred to as glutes or buttock muscles, are a muscle group consisting of the gluteus maximus, gluteus medius, gluteus minimus and tensor fasciae latae muscles. They are found in the gluteal, or buttock region, overlying the posterior aspect of the pelvic girdle and the proximal part of the femur. Superficial abductors and extenders - group of large muscles that abduct and extend the femur. Includes the gluteus maximus, gluteus medius, gluteus minimus and tensor fascia lata. Deep lateral rotators - group of smaller muscles that mainly act to laterally rotate the femur. Intergluteal cleft. The intergluteal cleft or just gluteal cleft, also known by a number of synonyms, including natal cleft, butt crack, ass crack and cluneal cleft, is the groove between the buttocks that runs from just below the sacrum to the perineum, [1] so named because it forms the visible border between the external rounded protrusions.

Definition The buttock refers to the rounded bulge in the lower part of the gluteal region. The inferior extent of the buttock is marked by a gluteal fold of skin below. Medially, an intergluteal cleft separates the two buttock s from each other, while laterally they are bounded by the hip regions. It also extends from the iliac crest superiorly to the gluteal fold inferiorly. The gluteal fold is the crease formed by the inferior aspect of the buttocks and the posterior upper thigh. Medially, the region extends to the mid-dorsal line and is called the intergluteal cleft, which is the groove that separates the buttocks from each other. Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. [1] In birds, this is termed topography. Surface anatomy deals with anatomical features that can be studied by sight, without dissection. The gluteal region is an anatomically important area at the posterior aspect of the pelvis, which contains muscles critical to dynamic movements and upright stability of humans.[1][2] It is a key conduit for several important neurovascular structures passing into the lower limb.[3] The major muscles in this region are the gluteus maximus, medius, and minimus, of which the former is the largest.

Gluteal Muscles. The gluteal muscles can be divided into 2 groups that are responsible for the main movements of the hip joint Hip joint The hip joint is a ball-and-socket joint formed by the head of the femur and the acetabulum of the pelvis. The hip joint is the most stable joint in the body and is supported by a very strong capsule and several ligaments, allowing the joint to sustain forces.

The hip joint The hip joint is a ball-and-socket joint, formed by the femoral head and the acetabulum (Fig. 1, see Standring, Fig. 80.15). The articular surfaces are spherical with a marked congruity; this limits the range of movement but contributes to the con-siderable stability of the joint. Gluteus Minimus. The gluteus minimus is the smallest and deepest of the gluteal muscles. Its job is to abduct the thigh and stabilize the hips/pelvis during walking, running, or standing on one leg. In addition, its anterior portion provides internal rotation to the thigh, while its posterior portion provides external rotation to the thigh.
