ANATOMY

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. They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities.

Detailed explanation-2: -There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.

Detailed explanation-3: -Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs. Irregular bones such as those of the face have no characteristic shape.

Detailed explanation-4: -The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1).

Detailed explanation-5: -Long bone – has a long, thin shape. Short bone – has a squat, cubed shape. Flat bone – has a flattened, broad surface. Irregular bone – has a shape that does not conform to the above three types.
