what are the five functions of a skeleton?

Answer 1

The bone has five main functions:

1. Support
That's about everything just covered above
2. Protection
They keep organs away from damage, such as the rib cage and the skull.
3. Movement
That's covered above, also.
4. Storage
The bone stores fat and some minerals.
5. Blood cell formation
The bone is the place that most of your blood components are made.

Functions of the skeleton
1)Support
Without a skeleton we would be like jelly and flop all over the floor. In fact, one could argue that our skeleton is an important evolutionary trait that has helped our species progress. Our skeleton provides the body with shape and forms a frame under the skin. The body is held in position by muscles which are firmly attached to the bones.

2)Protection
Vital organs are protected from damage by the different bones of the skeleton. The brain is protected by the cranium, the heart and lungs are surrounded by the ribs and the sternum, and the spinal cord passes through the centre of the vertebral column.

3)Movement
If the skeleton did not have joints, it would be impossible to move. Bones are linked at the joints and muscles allow them to move. The way the bones grow affects the movement in the joints.

Transient joints or immovable joints have fused together (always after birth). An example of this is the "soft spot" on a baby's head. The skull has not grown together completely, but will fuse as the child grows up. Permanent joints are ones that stay moving throughout life, unless injured or diseased.

Gaps between the bones in a baby's skull give it room to grow before they fuse together.

4)Blood production
Blood cells are made in the red bone marrow in the centre of certain bones of the skeleton. The main sites of blood cell production are the pelvic girdle, ribs, sternum and the vertebrae.

Bones are not completely solid, as they would be too heavy to carry around. Blood vessels feed the centre of the bones, and calcium is stored and released to the tissues which require it. Also stored inside the bones are different types of bone marrow - red and yellow. Red bone marrow produces blood, while yellow bone marrow stores fat but can be converted to red if the body is in need of more red/white blood cells.

5)Store for minerals
The main mineral that is stored in the skeleton is calcium. The body needs calcium to harden the bones. This hardening process is called ossification and happens throughout childhood. The skeleton is also continually replacing itself throughout our adult life. Calcium is transported in the bloodstream to the sites of bone growth or where replacement is needed (at an injured bone).

Answer 3

1. Bones provide a rigid frame work, known as the skeleton, that support and protect the soft organs of the body.

2. supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing.

3. protects the soft body parts. The fused bones of the cranium surround the brain to make it less vulnerable to injury. Vertebrae surround and protect the spinal cord and bones of the rib cage help protect the heart and lungs of the thorax.

4. work together with muscles as simple mechanical lever systems to produce body movement.

5. change shape or remodel in response to variations in mechanical stress.

Answer 4

1. Support of the body (eg. spine) 2. Movement (eg. humerus) 3. Attachment for muscles and tendons (eg. hip bones) 4. Storage of bone marrow, where you find the stem cells for blood components (red blood cells, white blood cells, platelets etc.) 5. Protection — Bones can serve to protect internal organs, such as the skull protecting the brain or the ribs protecting the heart and lungs. Hope I helped! :)
