The 3 Main Parts of The Muscular System
Skeletal muscle – this type of muscle are specialised tissue that are attached to bones which allows movement in the body.
Smooth muscle –these muscles are located in various internal structures including the digestive tract, uterus and blood vessels such as arteries.
Cardiac muscle –these muscles are the muscles that are specific to the heart.
What Do The Muscles Do?
Muscular system functions include mobility, stability, posture, circulation, and more. Muscles allow a person to move, speak, and chew. They control heartbeat, breathing, and digestion. Other seemingly unrelated functions, including temperature regulation and vision, also rely on the muscular system.
Threats?
Threats include possible injuries such as: sprains, strains, cramps, spasms, splints, and tendinitis. Sprains and strains both involve a stretch and/or tear of part of the muscular system which causes the harm towards the muscular system.
