In addition, the bones of the skull and face are counted as separate bones, despite being fused naturally. Some reliable sesamoid bones such as the pisiform are counted, while others, such as the hallux sesamoids, are not. Individuals may have more or fewer bones than the average (even accounting for developmental stage) owing to anatomical ...
Nereid, or Neptune II, is the third-largest moon of Neptune. It has the most eccentric orbit of all known moons in the Solar System . [ 4 ] It was the second moon of Neptune to be discovered, by Gerard Kuiper in 1949.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

Anatomical terms of bone [ edit on Wikidata ] The xiphoid process ( / ˈ z ɪ f ɔɪ d / ), also referred to as the ensiform process , xiphisternum , or metasternum , constitutes a small cartilaginous process (extension) located in the inferior segment of the sternum , typically ossified in adult humans.

The sternum (pl.: sternums or sterna) or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Shaped roughly like a necktie, it is one of the largest and longest flat bones ...
Diameter of canaliculi in human bone is approximately 200 to 900 nm. [1] In bovine tibia diameter of canaliculi was found to vary from 155 to 844 nm (average 426 nm). [ 2 ] In mice humeri it varies from 80 to 710 nm (average 259 nm), while diameter of osteocytic processes varies from 50 to 410 nm (average 104 nm).
On this (latter) metric, the most attractive ratio of leg to body for men (as seen by American women) is 1:1, [12] matching the 'four heads:four heads' ratio above. A Japanese study using the former metric found the same result for male attractiveness but women with longer legs than body were judged to be more attractive. [ 13 ]
Anatomical terms of bone [ edit on Wikidata ] The pelvic inlet or superior aperture of the pelvis is a planar surface which defines the boundary between the pelvic cavity and the abdominal cavity (or, according to some authors, between two parts of the pelvic cavity, called lesser pelvis and greater pelvis).
