Across
- 3. What is the the functional unit of skeletal muscle called?
- 7. Golgi tendon organs detect ___________ generated by active muscle to protect muscle from sudden/excessive load.
- 9. This enzyme breaks down acetycholine at the junction.
- 11. Increasing muscle force involved activation of new motor units by the nervous system, this is termed?
- 13. The synapse between a neuron and muscle is known as the __________ junction.
- 15. When this ion binds to troponin, tropomyosin moves away from blocking position.
Down
- 1. Contractile elements of muscle fibers are called _______.
- 2. Thin filaments of skeletal muscle consist of actin, tropomyosin, and __________.
- 4. When muscle torque/load torque >1; this type of muscle contraction is called?
- 5. Merkel disks are ___________ adapting mechanoreceptors.
- 6. The orderly recruitment from smallest to largest motor unit is known as the ___________ (no spaces).
- 8. _________ responds to and modulates changes in the length of extrafusal muscle fibers (no spaces).
- 9. Cross bridges detach with fresh ________ and returns to original conformation.
- 10. This phenomenon occurs when the muscle fiber is stimulated so rapidly that it does not have a chance to relax between stimuli.
- 12. This part of the brain is important for removing inappropriate features of movement.
- 14. Thick filaments of skeletal muscle consist of this molecule.
