Across
  1. 2. Contraction of some fibers in skeletal muscle at any given time
  2. 4. A narrow extracellular space between the presynaptic and postsynaptic neurons
  3. 6. heat of fibrous connective tissue that encloses a muscle
  4. 8. Time period following stimulation during which a neuron or muscle fiber will not respond to a stimulus
  5. 11. Time between the application of a stimulus and the beginning of a response in a muscle fiber.
  6. 12. Contractile fibers within muscle cells
  7. 13. Protein that, with actin, contracts and relaxes muscle fiber
  8. 14. cordlike or bandlike mass of white fibrous connective tissue that connects a muscle to a mone
  9. 15. Stimulation level that must be exceeded to elicit a nerve impulse or a muscle contraction
Down
  1. 1. a chemical that an axon end secretes to stimulate a muscle fiber to contract on the neuron to fire and impulse
  2. 3. End of a muscle that attaches to a relatively immovable part .
  3. 5. End of a muscle attached to a moveable part
  4. 7. Structural and functional unit of myofibril
  5. 9. A protein in a muscle fiber forms filaments that slide between elements of the protein myosin, contracting muscle fibers.
  6. 10. Brief muscular contraction followed by relaxation.
  7. 13. neuron A neuron that transmits impulses from the central nervous system to an effector
