Anatomy Chapter 10 Vocab

4. A molecule that can store energy in its phosphate bonds.
7. A muscle can return to its original length when relaxed due
11. The ability to respond to a stimulus, which may be delivered from a neuron or a hormone.
12. The plasma membrane of muscle fibers
13. The breakdown of glucose or other nutrients in the presence of oxygen to produce carbon dioxide, water, and ATP.
15. Allows muscle tissue to pull on its attachment points and shorten with force.
18. Contributes to muscle fatigue.
19. The cytoplasm of muscle fibers

1. Anaerobic process that breaks down glucose (sugar) to produce ATP;
2. The basic contractile unit of muscle fiber composed of two main protein filaments—actin and myosin
3. The site where a motor neuron’s terminal meets the muscle fiber—called
5. Middle layer of connective tissue that separates each fascicle. Common in the muscles of the limbs
6. Individual bundles of muscle fibers
8. The amount of oxygen needed to compensate for ATP produced without oxygen during muscle contraction.
9. the specialized smooth endoplasmic reticulum, which stores, releases, and retrieves calcium ions
10. Muscle can be stretched or extended.
14. The primary energy currency of the cell, a high-energy molecule that stores and releases energy for various cellular processes
16. The forceful movement of the myosin head, pulling the actin filament and causing muscle contraction, driven by the hydrolysis of ATP
17. Connective tissue that surrounds each muscle, providing separation and the ability to move independently
