Study Notes
Body Mass Index (BMI)
- A method to estimate body density indirectly.
- Used to assess body weight relative to height, indicating potential health risks.
Contractile Cells
- Specialized cells that can change shape due to unique membrane and cytoskeleton structures.
- Essential for movement, such as muscle contraction.
Intrinsic Beat
- Refers to the natural contraction cycle of cardiac muscles.
- Important for maintaining a consistent heart rhythm without external stimuli.
Peristalsis
- Characterized by weak, pulsating contractions in the digestive system.
- Mechanism for moving food and waste through the gastrointestinal tract.
Muscle Fiber
- Individual cells that make up muscle tissue.
- Contribute to muscle contraction and overall movement.
Motor Nerve Cells
- Nerves that specifically control the action of skeletal muscle fibers.
- Essential for voluntary movement and muscle coordination.
Z-line
- A distinct line seen across striated muscle fibers.
- Marks the boundaries of individual sarcomeres, fundamental units of muscle contraction.
