Australopithecus (informal australopithecine or australopith, although the term australopithecine has a broader meaning as a member of the subtribe Australopithecina which includes this genus as well as Paranthropus, Kenyanthropus, Ardipithecus, and Praeanthropus) is an extinct genus of hominins.

The bonobo (Pan paniscus), formerly called the pygmy chimpanzee and less often, the dwarf or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus Pan; the other is Pan troglodytes, or the common chimpanzee.

The pelvis (plural pelves or pelvises) is either the lower part of the trunk of the human body between the abdomen and the thighs (sometimes also called pelvic region of the trunk) or the skeleton embedded in it (sometimes also called bony pelvis, or pelvic skeleton).

Percutaneous vertebroplasty

Vertebroplasty and kyphoplasty are similar medical spinal procedures in which bone cement is injected through a small hole in the skin (percutaneously) into a fractured vertebra with the goal of relieving back pain caused by vertebral compression fractures.

Spinal disc herniation

Spinal disc herniation, also known as a slipped disc, is a medical condition affecting the spine in which a tear in the outer, fibrous ring of an intervertebral disc allows the soft, central portion to bulge out beyond the damaged outer rings.

Spine of scapula

The spine of the scapula or scapular spine is a prominent plate of bone, which crosses obliquely the medial four-fifths of the scapula at its upper part, and separates the supra- from the infraspinatous fossa.
