  2. Ischial tuberosity - Wikipedia

    en.wikipedia.org/wiki/Ischial_tuberosity

    The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, [1] or as a pair the sitting bones, [2] is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.

    en.wikipedia.org/wiki/Ischium

    The superior ramus is a partial origin for the internal obturator and the external obturator muscles. The inferior ramus serves partially as origin for part of the adductor magnus muscle and the gracilis muscle. The inferior ischial ramus joins the inferior ramus of the pubis anteriorly and is the strongest of the hip (coxal) bones.

  4. Hip bone - Wikipedia

    en.wikipedia.org/wiki/Hip_bone

    3D model of human hip bone. The ischium forms the lower and back part of the hip bone and is located below the ilium and behind the pubis. The ischium is the strongest of the three regions that form the hip bone. It is divisible into three portions: the body, the superior ramus, and the inferior ramus. The body forms approximately one-third of ...

    These terms are derived from tuber (Latin: swelling)., [8] as is also protuberance, which occasionally is synonymous with "tuberosity". A ramus (Latin: branch) refers to an extension of bone, [9] such as the ramus of the mandible in the jaw or superior pubic ramus. Ramus may also be used to refer to nerves, such as the ramus communicans.

    Its oblique fibres descend laterally, converging to form a thick, narrow band that widens again below and is attached to the medial margin of the ischial tuberosity. It then spreads along the ischial ramus as the falciform process, whose concave edge blends with the fascial sheath of the internal pudendal vessels and pudendal nerve.

  7. Pubis (bone) - Wikipedia

    en.wikipedia.org/wiki/Pubis_(bone)

    The pubic bone is made up of a body, superior ramus, and inferior ramus (Latin: branch). The left and right coxal bones join at the pubic symphysis. It is covered by a layer of fat – the mons pubis. The pubis is the lower limit of the suprapubic region. In the female, the pubis is anterior to the urethral sponge.

    Anatomical terms of bone [ edit on Wikidata ] The iliac fossa is a large, smooth, concave surface on the internal surface of the ilium (part of the three fused bones making the hip bone ).

  9. Acetabulum - Wikipedia

    en.wikipedia.org/wiki/Acetabulum

    Organisms in the dinosauria clade are defined by a perforate acetabulum, which can be thought of as a "hip-socket". The perforate acetabulum is a cup-shaped opening on each side of the pelvic girdle formed where the ischium, ilium, and pubis all meet, and into which the head of the femur inserts.
