Protection: It protects our internal organs. The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).

What does the skeleton protects?

Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine. Stores minerals: Bones hold your body’s supply of minerals like calcium and vitamin D.

How does the skeleton support and protect?

Bones provide a rigid framework, known as the skeleton, that support and protect the soft organs of the body. The skeleton supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing. The skeleton also protects the soft body parts.

Which bones protect the brain?

Cranium. The eight bones that protect the brain are called the cranium. The front bone forms the forehead. Two parietal bones form the upper sides of the skull, while two temporal bones form the lower sides.

Which set of bones protects the heart and lungs in the human skeleton?

The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs. Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.

How does the skeleton allow us to move?

Bones don’t work alone — they need help from the muscles and joints. Muscles pull on the joints, allowing us to move. … Muscles make up half of a person’s body weight. They are connected to bones by tough, cord-like tissues called tendons, which allow the muscles to pull on bones.

What is bone made up from?

Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.

What is the axial skeleton?

The axial skeleton consists of the braincase (cranium) and the backbone and ribs, and it serves primarily to protect the central nervous system. The limbs and their girdles constitute the appendicular skeleton.

What connects bone to muscle?

Tendons attach muscles to bones. The tendon pulls the bone, making it move.
