Across
- 2. A fiber can generate more force through rapid, repeated stimulation, wherein the force from a given twitch can build upon the residual force from a previous one.
- 3. The plasma membrane of a muscle fiber.
- 7. Resevoir for calcium in the muscle fiber.
- 12. Source for growth hormone and antidiuretic hormone.
- 14. Hormone which typically declines during exercise
- 15. Covers crossbride binding sites on actin until fiber receives an action potential.
- 16. Contraction where force is exerted but muscle does not change length.
- 17. Motor neurons are myelinated due to the presence of these on the axon.
- 19. A bundle of muscle fibers.
- 20. Level of depolarization necessary to generate an action potential.
Down
- 1. Area of the brain which exerts great control over endocrine function.
- 4. Allows conduction of action potential across synaptic cleft.
- 5. In order to maintain glucose levels during exercise, the body will create new glucose, a process called
- 6. Part of a neuron which receives signals from other neurons.
- 8. Potent catacholamine from the adrenal medulla.
- 9. The association between the axon of one neuron and the dendrite of another.
- 10. One motor neuron and all the muscle fibers it innervates.
- 11. Functional/Contractile unit of the myofibril.
- 13. Muscle fiber type with abundant mitochondria.
- 18. Subdivision of nervous system bringing signals into the CNS.
