The Bones Anatomy

Short bones are roughly cube shaped and have only a thin layer of compact bone surrounding. Newborn babies are actually born with many more bones than this around 300 but many bones grow together or fuse as babies become older.

Types long bones are characterized by a shaft the diaphysis that is much longer than its width. There are 206 bones in a typical human body providing a range of important functions. The structure of a long bone allows for the best visualization of all of the parts of a bone figure 1.

Flat bones are thin and generally curved with two parallel layers of compact bones sandwiching. Anatomy and physiology of axial skeleton dinosaur skeleton human muscles skeleton diagram anatomical skeleton fish skeleton snake skeleton human spine anatom. A long bone has two parts.

The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The anterior markings of the humerus bone. The skeleton of an adult human is made up of 206 bones of many different shapes and sizes.

The axial skeleton runs along the bodys midline axis and is made up of 80 bones in the following regions. Seventeen muscles attach to the scapula and it articulates with the clavicle to form the shoulder girdle or pectoral girdle which supports movements of the humerus. Added together your bones make up about 15 of your body weight.

Short bones include the carpal and tarsal bones patellae and sesamoid bones.

The axial skeleton comprising the spine chest and head contains 80 bones.

The four general categories of bones are long bones short bones flat bones and irregular bones. The scapula is a flat triangular shaped bone that lies adjacent to the posterior surface of ribs. The appendicular skeleton comprising the arms and legs including the shoulder and pelvic girdles contains 126 bones bringing the total for the entire skeleton to 206 bones.
