📖 1. Muscular system overview

🔑 Key Concepts & Definitions

  • Muscular system composition: The muscular system is made up of muscle tissue (muscle fibers) along with blood vessels, nerves, and connective tissue. Muscle tissue is highly specialized for contraction, enabling movement when stimulated.

  • Muscle tissue: Specialized tissue capable of contracting or shortening to produce movement. It is found throughout the body, beneath the skin, and surrounding internal organs and blood vessels.

  • Three types of muscle:

    • Skeletal muscle: Attached to bones, responsible for skeletal movements.
    • Cardiac muscle: Located in the walls of the heart; involuntary and rhythmic.
    • Smooth muscle: Found in walls of hollow internal organs; involuntary, slow, and rhythmic.
  • Location of muscle tissue:

    • Beneath skin (superficial muscles)
    • Deep within the body surrounding internal organs
    • Surrounding blood vessels
