Bone dissection Essay

September 21, 2017 Construction

The skeletal system is made up of gristle and bone. Both bone and gristle are connective tissues. that is. they are composed of cells in a matrix with intracellular fibres. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would stand for cells. the gelatin the support stuff for matrix. and the pieces of coconut the intracellular fibres. By altering the sums of each ingredient and adding excess substances. we can bring forth a stuff that is really difficult like bone and can defy weight or softer like gristle which can be used as a buffering stuff.

In this exercising. we will analyze a fresh altogether poulet bone to analyze bone construction.
