MICROANATOMY

Detailed explanation-1: -The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones.

Detailed explanation-2: -There are two types of bone ossification, intramembranous and endochondral.

Detailed explanation-3: -Several classifications can be proposed to separate bone subtypes. Overall, there are five generalized varieties of human bones (long, short, flat, sesamoid, and irregular) and two architectural subtypes, cortical and trabecular bones.

Detailed explanation-4: -For vertebrate animals, bones are often the best preserved traits, and as such give some of the greatest insights into their evolutionary relationships. Classifying bones is vital to be able to compare them between species.
