Study Notes
Muscle Structure and Components
- Blood Vessel: Essential for oxygen and nutrient delivery; serves as the transportation system for blood to and from muscle tissue.
- Perimysium: A connective tissue sheath that encases fascicles, ensuring structural integrity and facilitating force transmission among muscle fibers.
- Epimysium: The outermost layer of connective tissue surrounding entire skeletal muscles, separating muscles from surrounding tissues and organs.
- Muscle Fiber: The basic contractile unit of muscle; also known as a muscle cell, responsible for muscle contraction and force generation.
- Fascicle: A collection of muscle fibers grouped together; plays a crucial role in the organization and function of skeletal muscles.
- Endomysium: A delicate layer of connective tissue that surrounds each individual muscle fiber, providing support and nourishment.
- Tendon: Strong, fibrous cords composed mostly of collagen, connecting muscles to bones; facilitate movement by transmitting muscular force across joints.
- Bone: The rigid framework of the body providing structure, support, and protection to vital internal organs, integral to movement and posture.
