ANATOMY

Detailed explanation-1: -The skeleton is traditionally divided into two major parts: the axial skeleton and the appendicular skeleton, both of which are pictured in Figure 14.2. 3. The axial skeleton forms the axis of the body. It includes the skull, vertebral column (spine), and rib cage.

Detailed explanation-2: -Today, we’re going to look at the four main organs of the skeletal system: bones, cartilage, ligaments, and tendons.

Detailed explanation-3: -Synovial joints are characterized by the presence of an articular capsule between the two joined bones. Bone surfaces at synovial joints are protected by a coating of articular cartilage. Synovial joints are often supported and reinforced by surrounding ligaments, which limit movement to prevent injury.

Detailed explanation-4: -The adult human skeleton is made up of 206 bones. There are 5 main shapes of bones: long (such as the upper arm), short (such as the hand), flat (such as the ribs), irregular (such as the vertebrae) and sesamoid (such as the kneecap). Joints-an area where 2 or more bones come together.
