Human Body Diagram Muscular Development
1. Movement – Muscle tissues contract causing movement and move materials throughout the body, blood, food to digestive, and air.
2. Warmth – Creates heat as they contract.
3. Posture – Maintains
Ability to contract – Forcing contraction of fibers in cells to shorten.
Ability to be stretched – Muscles stretch across joints (muscle joint) to link one bone with another and work in groups to respond to the nerve impulses.
Ability to respond to a stimulus – Muscle cells are capable of contracting longitudinally in response to nervous stimulation. The muscle cells contain small contractile strands of protein (myofibrils). They contract when stimulated, and return to their original state as soon as the stimulation ceases. Muscle fibers and muscle cells are distinguished according to their make up.
