This usually develops embryologically from the mesenchymal [mehz ehn KI mul] blastema [blast EE mah]. Some animals, like jellyfish and annelids [ANN uh lidz], have a hydrostatic type of this, which uses pressure to produce motion. Spicules and cuttlebones fulfill a similar purpose to this, though they aren't really one, and this structure comes in exo- and endo- varieties, the latter being the one found in humans. Its constituent parts are formed by ossification and can be affected by osteoporosis. Name this support structure that in humans usually consists of two hundred six bones.
