There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid. Let’s go through each type and see examples. 1. Flat Bones Protect Internal Organs. There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and ...
Shape Classification. The 206 bones that compose the adult skeleton are divided into five categories based on their shapes (Figure 6.6). Their shapes and their functions are related such that each categorical shape of bone has a distinct function.
Short bones are roughly cube shaped. The bones of the wrist and ankle are examples. Sesamoid bones are a special type of short bone that form in a tendon (for example, the patella). They vary in size and number in different individuals. Some sesamoid bones act to alter the direction of pull of a tendon. The function of others is not known.
There are five types of bones: Long Bones --- Femur is a good example. Short Bones -- Carpals. Irregular bones -- vertebrae. Flat bones -- The bones of the skull are a prime example. Sesamoid ...
The classification of a long bone includes having a body that is longer than it is wide, with growth plates (epiphysis) at either end, having a hard outer surface of a compact bone and a spongy inner known a cancellous bone containing bone marrow.

Classification of Bones Long Bones. The bones of the body come in a variety of sizes and shapes. 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.
Bones are composed of two types of tissue: 1. Compact (cortical) bone: A hard outer layer that is dense, strong, and durable. It makes up around 80 percent of adult bone mass. 2. Cancellous ...
Bone type: One of the four basic bone shapes in the human skeleton. Long bones: Long bones have a tubular shaft and articular surface at each end. The major bones of the arms (humerus, radius, and ulna) and the legs (the femur, tibia, and fibula) are all long bones. Short bones: Short bones also have a tubular shaft and articular surfaces at each end but are much smaller.
Pneumatic Bones: Pneumatic bones can also be categorized under the irregular bones.The characteristic difference is the presenceof large air spaces in these bones which make them light in weight and thus they form the major portion of skull Examples: Sphenoid, Ethmoid, Maxila etc. Fig. Sphenoid, Ethmoid, Maxila , Pnematic Bones.
