Jill Ferrari, David A. Hopkinson, Alf D. This study introduces a new technique to measure bone size and shape.

Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These can be of several types, including direct and indirect. Direct being the direct result of differences prescribed by the Y-chromosome, and indirect being a characteristic influenced indirectly e. Sexual dimorphism is a term for the phenotypic difference between males and females of the same species.

Identifying the sex of a skull

Where is the wisdom we have lost in knowledge? Where is the knowledge we have lost in information? Techniques are not ends in themselves, they are only as good as the answers they provide. The answers are only as good as the questions, and the questions are only as good as the insights generated from observations made using the technique. The use of densitometry has led to several misconceptions: 1 volumetric bone mineral density BMD increases during growth. It does not.

The morphological differences between women and men are the result of differences in the volume and proportion of similar anatomical features. Generally speaking, the female skeleton is not as massive; it is smoother and more delicate with impressions—hollows or bumps—that serve as muscle insertions or provide passage for tendons, which are less accentuated. The more highly developed musculature in men marks the skeleton more. The female thoracic cage is generally more rounded and not as big as in the male. Proportionately, the skeletal width of the shoulders is the same as in the male, but the larger muscular development of the latter makes it seem wider.

A female's skeleton is usually much smoother and less knobby than a male's. A male's skeleton is usually thicker, rougher and appears more bumpy. ○ Due to the fact that males have larger muscles and therefore their skeletons require stronger attachment sites.

Male or Female?

Recent observations suggest that throughout life the size of the vertebral bodies in females is smaller than that in males even after accounting for differences in body size. To confirm these reports and to determine whether similar differences exist in the appendicular skeleton, detailed measurements of the sizes of the vertebrae and the femur were obtained using computed tomography in 30 pairs of prepubertal boys and girls matched for age, height, and weight. Anthropometric parameters as well as gender influenced the cross-sectional area of the vertebrae. In contrast to these findings in the axial skeleton, gender status did not influence the size of the bones in the appendicular skeleton, and neither the cross-sectional area 3. These values, however, correlated strongly with all anthropometric indexes, and multiple regression analyses indicated that both measurements were primarily related to weight.

Несмотря на свой внушительный вид, дешифровальное чудовище отнюдь не было островом в океане.

В трубке раздались длинные гудки. Беккер решил, что трубку поднимут на пятый гудок, однако ее подняли на девятнадцатый. - Городская больница, - буркнула зачумленная секретарша. Беккер заговорил по-испански с сильным франко-американским акцентом: - Меня зовут Дэвид Беккер. Я из канадского посольства.
