What are the 20 parts of the skeletal system?
The skeleton
- 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.
- Hands – wrist bones (carpals), metacarpals and phalanges.
- Pelvis – hip bones.
What are parts of skeletal system?
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 is skeletal system parts and functions?
The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. The skeletal system is also called the musculoskeletal system.
How many parts does the skeletal system have?
two parts
Regardless of age or sex, the skeletal system can be broken down into two parts, known as the axial skeleton and the appendicular skeleton.
What are the 3 main parts of the skeleton?
An internal or external, protective framework of bone, cartilage, or other rigid material, supporting and containing the organs of the human body is termed as skeleton. Skeleton has three components: bones, joints and cartilage.
What are the 4 components of bone?
The skeletal system includes four basic components, although some sources include a fifth, the joints. The four are the bones, which make up most of the mass of the skeletal system; cartilage, which acts mainly as padding; ligaments, which usually connect bones to bones; and tendons, which join muscles to bones.
What are the 6 functions of the skeleton?
Functions. The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation.
What are the 6 functions of the skeletal system?
It is composed of 270 bones at birth and decreases to 206 bones by adulthood after some bones have fused together. The human skeleton serves six major functions: support, movement, protection, production of blood cells, storage of ions, and endocrine regulation.
What are the 80 axial bones?
The axial skeleton consists of 80 bones:
- The skull, which contains 22 bones, from which 8 are cranial and 14 are facial,
- 6 middle ear ossicles (3 in each ear),
- 1 hyoid bone in the neck,
- 26 bones of vertebral column,
- 1 chest bone (sternum), and.
- 24 ribs (12 pairs).
What are the most important parts of the skeletal system?
The axial skeleton contains 80 bones, including the skull, spine and rib cage. It forms the central structure of the skeleton, with the function of protecting the brain, spinal cord, heart and lungs.
What are 3 main parts of the skeletal system?
These are (1) the axial, comprising the vertebral column—the spine—and much of the skull, and (2) the appendicular, to which the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs belong.
What are types of skeleton?
The three types of skeleton designs are hydrostatic skeletons, exoskeletons, and endoskeletons.
