axial skeleton
|
|
|
the auditory ossicles in the middle ear do what
|

|
|
|
axial skeleton includes the
|
skull,bones of the vertebral column and the chest
|
|
|
appendicular skeleton includes the
|
bones of the pectoral (shoulder) girdle, and upper limbs, and then the pelvic (hip) girdle and the lower limbs.
|
|
|
long bones consist of a
|
shaft and a variable number of extemities (ends)
|
|
|
why are long bones slightly curved?
|
for strength
|
|
|
long bones
a curved bone does what |
absorbs the stress of the body's weight at several different points, so that it is eventually distributed.
|
|
|
long bones
if the bones were straight.. |
the weight of the body would be unevenly distributed and the bone would fracture more easily.
|
|
|
long bones consist mostly of
|
compact bone tissue in their diaphyses
|
|
|
long bones also have considerable amounts of
|
spong bone tissue in their epiphyses
|
|

the shapes of bones determine the
|
functions
