Study Notes
Muscle Overview
- Muscle comprises approximately 40% of an individual's body weight.
- Defined as a band of fibrous tissue capable of contraction, facilitating movement and body part positioning.
Muscle Tissue Structure
- Muscle tissues consist of muscle cells, which contain myofibrils.
- Myofibrils are the contractile units within muscle cells, spanning the entire length of the muscle fiber.
- Sarcomere is the fundamental unit of muscle, consisting of fibrous proteins that slide past one another, creating distinct dark and light bands observable under microscopy.
Muscle Energy Source
- Muscle cells produce movement through chemical energy conversion from Adenosine Triphosphate (ATP).
- ATP is generated by metabolizing food into usable chemical energy.
Functions of Muscle
- Key functionalities include:
- Posture and muscle tone maintenance
- Stability and support for bodily structures
- Facilitation of digestion
- Regulation of body temperature through heat production
- Mobility and movement execution
- Circulatory support
- Organ protection
- Assistance in respiratory actions
- Contribution to urination processes
Lever Systems and Movement
- Lever systems involve the interaction of bones and muscles to create movement.
- Main functions of lever systems include generating muscular effort to lift or move loads and increasing movement speed.
Temperature Regulation
- Maintaining a constant body temperature is crucial for healthy survival and is supported by muscle activity, which contributes to heat production.
