Question

What is a locomoter system?

Answer 1

Locomotor system

1. The musculoskeletal system is also called the locomotor system.
2. It is composed of a skeleton, skeletal muscle, ligaments, tendons, cartilage, joints, and other connective tissue.
3. These parts perform together to move your body. the musculoskeletal system is divided into two broad parts:

• The muscular system:

1. It includes all types of muscles in the body.
2. Specifically, skeletal muscle is a muscle that acts on the joints of the body to produce movement.
3. In addition to muscles, the muscular system contains tendons that connect muscles to bones.

• The skeletal system:

1. Its main component is skeletal bones.
2. Bones joint with each other and form joints, giving our body a stiff and flexible skeleton.
3. Bone and joint integrity and function are supported by the accessory structures of the skeletal system. Articular cartilage, ligaments, and synovial bursa.

The parts of the musculoskeletal system are:

Bones:

1. Bones of all shapes and sizes support your body, protect organs and tissues, store calcium and fat, and produce blood cells.
2. A hard outer shell of bone surrounds the spongy center.
3. Bones give the structure and shape of your body.
4. They work with muscles, tendons, ligaments, and other connective tissue to help you move.

Cartilage:

1. A type of connective tissue, cartilage protects the bones of the chest along the joints and spine.
2. The hard, rubbery cartilage prevents the bones from rubbing against each other.
3. There is also cartilage in the nose, ears, pelvis, and lungs.

Joints:

1. Bones form joints.
2. Some joints have a wide range of motion, including ball-and-socket and socket shoulder joints.
3. Other joints, such as the knee, allow the bones to move back and forth, but they cannot rotate.

Muscles:

1. Each muscle is made up of thousands of elastic fibers.
2. Your muscles allow you to move, stand upright, and stay still. Some muscles help you run, dance, and lift.
3. You use someone else to write your name, close the button, talk, and swallow.

Ligaments:

Ligaments are made of tough collagen fibers that help connect bones and stabilize joints.

Tendons:

1. Tendons connect muscles to bones.
2. Tendons are made of fibrous tissue and collagen and are strong but not very elastic.

Musculoskeletal systems work as:

1. The nervous system (brain and nerves) sends messages to activate (spontaneous) skeletal muscles.
2. In response to the message, the muscle fibers contract (tension).
3. When the muscles are activated or contracted, the tendons are pulled.
4. Tendons attach muscles to bones.
5. The tendons pull and move the bones.
6. To relax the muscles, the nervous system sends another message.
7. It causes muscle relaxation or deactivation.
8. The relaxed muscles release tension and move the bones to a resting position.
