Dog anatomy. Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [ 1] as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that ...

Anatomical terms of bone. [ edit on Wikidata] The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Its rough surface gives attachment to various muscles (via tendons) and it has openings for blood vessels. From its borders, the mastoid part articulates with two other bones.
The fourchette may be torn during delivery due to the sudden stretching of the vulval orifice, or during copulation. To prevent this tearing in a haphazard manner, obstetricians and, less frequently, midwives may perform an episiotomy, which is a deliberate cut made in the perineum starting from the fourchette and continuing back along the perineum toward the anus.
The spotted hyena ( Crocuta crocuta ), also known as the laughing hyena, [ 3] is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. [ 1]
