*the human skeleton is the ‘internal framework’ of the ‘body’*
.
It is composed of 270 bones at birth – this total decreases to 206 bones by adulthood after some bones have fused together.
The bone mass in the skeleton reaches maximum density around age 30.
The human skeleton can be divided into the axial skeleton and the appendicular skeleton.
The axial skeleton is formed by the vertebral column, the rib cage, the skull and other associated bones.
The appendicular skeleton, which is attached to the axial skeleton, is formed by the shoulder girdle, the pelvic girdle and the bones of the upper and lower limbs
.
*the human skeleton performs 6 major functions* —>
support,
movement,
protection,
production of blood cells,
storage of minerals
and endocrine regulation
.
The human skeleton is not as sexually dimorphic as that of many other primate species, but subtle differences between sexes in the morphology of the skull, dentition, long bones, and pelvis exist.
In general, female skeletal elements tend to be smaller and less robust than corresponding male elements within a given population.
(the human female pelvis is also different from that of males in order to facilitate child birth)
(unlike most primates, human males do not have penile bones)
(one of the types of tissue that makes up bone is the mineralized osseous tissue, also called bone tissue, that gives it rigidity and a honeycomb-like three-dimensional internal structure)
.
[other types of ’tissue’ found in bones include…]
‘marrow’
.
‘endosteum’ / ‘periosteum’
.
‘nerves’
.
‘blood vessels’
.
‘cartilage’
