is an organ system of over 650 muscles, responsible for body movement, maintaining posture, circulating blood, and generating heat, using three muscle types: skeletal (voluntary movement), cardiac (heartbeat), and smooth (organ movement). Muscles work by contracting (shortening) and relaxing, controlled by the nervous system, and are vital for daily activities like walking, speaking, and breathing, as well as internal functions like digestion.

💠 Types of Muscles :

🔴 Skeletal Muscles: Attached to bones via tendons, enabling voluntary movement (running, writing) and posture. They have fast-twitch (quick bursts) and slow-twitch (endurance) fibers.

🔴 Cardiac Muscle: Found only in the heart, it's involuntary and pumps blood throughout the body.

🔴 Smooth (Visceral) Muscle: Involuntary muscles lining organs (stomach, intestines, blood vessels) that move substances through the body (food, blood).

💠 Key Functions :

🔴 Movement: Locomotion (walking, jumping) and internal motion (digestion, circulation).

🔴 Posture: Fine adjustments keep the body upright.

🔴 Stability: Tendons stabilize joints (knee, shoulder).

🔴 Heat Production: Generates heat to maintain body temperature.

💠 How They Work:

🔴 Nervous System Signals: Nerves send signals to muscle fibers.

🔴 Contraction: Muscle fibers (cells) contract (shorten) to create force.

🔴 Energy: Muscles use ATP (chemical energy from food) to power contraction.
Tendons: Connect muscles to bones, transferring force.
