How does the human skeleton support the human body?
The skeletal system supports and protects the body while giving it shape and form. This system is composed of connective tissues including bone, cartilage, tendons, and ligaments. Nutrients are provided to this system through blood vessels that are contained within canals in bone. The skeletal system stores minerals and fats and produces blood cells.
How does the skeleton protect the vital organs?
Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.

What body part of it protects major organs of the body?
Skeletal SystemSkeletal System (Bones, Joints) The skeletal system supports and protects the body's internal organs. The ribs protect the abdominal organs, which are both vulnerable to injury and dangerous to our well being when injured. The skull protects our brain which controls all functions of our bodies and minds.
Which skeleton is responsible for movement?
That contraction produces movement at the joints between bones. 5. Bones Are Grouped into the Axial Skeleton and the Appendicular Skeleton. Bones of the appendicular skeleton facilitate movement, while bones of the axial skeleton protect internal organs.
What are the bones that protect the brain?
These bones provide structure and protection and facilitate motion. Bones articulate to form structures. The skull protects the brain and gives shape to the face. The thoracic cage surrounds the heart and lungs. The vertebral column, commonly called the spine, is formed by over 30 small bones. Then there are the limbs (upper and lower) and the girdles that attach the four limbs to the vertebral column.
How does the skeleton move?
How does the skeleton move? Muscles throughout the human body are attached to bones. Nerves around a muscle can signal the muscle to move. When the nervous system sends commands to skeletal muscles, the muscles contract. That contraction produces movement at the joints between bones.
What are the main parts of a long bone?
Long Bones Have Three Main Parts to Them. The outside of a long bone consists of a layer of compact bone surrounding spongy bone. Inside a long bone is a medullary cavity filled with yellow bone marrow.
