What are the main parts of the skeleton?

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.

What are the 2 major parts of the axial skeleton?

The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton.

What are the 2 main functions of the skeletal system?

The main functions of the skeletal system

• Support – the skeleton keeps the body upright and provides a framework for muscle and tissue attachment.
• Posture – the skeleton gives the correct shape to our body.
• Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact.

What are the parts of skeleton?

Skeleton, Bony framework of the body. It includes the skull, vertebral column, collarbone, shoulder blades, rib cage, pelvic girdle and the bones of the hands, arms, feet, and legs. The skeleton supports the body and protects its internal organs.

What are the parts of the skeleton body?

The human skeletal system is comprised of bones, joints, cartilage, ligaments and tendons. The most basic part of the skeletal system, bones are hard connective tissue that connect to one another at joints. Cartilage acts as cushioning between bones to prevent them from rubbing against one another.

What are the bones of the skeleton?

The human skeleton is made up of 206 bones, including bones of the: Skull – including the jaw bone. Spine – cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx) Chest – ribs and breastbone (sternum) Arms – shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna.

What is the function of the skeleton?

Like the steel framework of a building, the functions of the skeleton and the bones is to provide rigidity, which gives the body shape and supports the weight of the muscles and organs. Without this structure, the body would collapse in on itself, compressing the lungs, heart and other organs–impairing their function.

What is the function of the human skeleton?

The human skeleton performs six major functions; support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation.
