The skeletal system works in conjunction with the muscular system to help a person move. Without the skeleton, humans and other animals would simply be a blob of tissue without any protection.

Full Answer

Humans have endoskeletons, which are skeletal systems that are located inside their bodies. The skeleton offers protection to the internal organs and the brain while helping the body keep its muscles, fat and skin upright. Muscles connect to the skeleton and contract and relax as the body moves.

The skeletal system is made of calcified bone and cartilage, and in the bone, red and white blood cells are made. The hard, calcified bones in the system also work with the circulatory system.

Unlike humans and other mammals, some animals such as crustaceans and insects have an exoskeleton, which is a skeleton outside the body. These skeletons are not made of bone, but rather hard calcified plates.

Besides bones and cartilage, the skeletal system consists of tendons and ligaments. Although teeth are considered to be part of the skeletal system, they are not bones. Teeth are made of dentin and enamel. Different bones that make up the skeletal system have different names. For example, the skull is called the cranium and the bones that protect the spinal cord are called vertebrae.

    How does the skeletal system respond to exercise?

    A:

    According to Brian Mackenzie for Sports Coach, the skeletal system responds to exercise by increasing the strength and flexibility of muscles. Exercising regularly improves body balance and muscle tone and eases pressure within joints. This reduces the risk of diseases within the skeletal and muscular systems.

    What are the effects of exercise on the skeletal system?

    A:

    Exercise influences the skeletal system primarily by the impact on the bones and the enhancement of muscle mass and power, according to Nature.com. This triggers a remodeling of bones, ligaments and tendons, which are made stronger and healthier through various forms of exercise. Two of the most effective ways to improve skeletal health are exercise and nutrition.
