Down: 1) . cell membrane of a muscle fiber.2) Isotonic contractions result in movement occurring at the joint and a change in the length of muscles (the force remains3) 4) A stimulus either causes an action potential or it doesn't. 6) 8)  protein functions as a motor protein in all three types of muscle tissue10)  The motor endplate is part of the sarcolemma where chemically regulated ion channels that respond to neural stimulation are found. Junctional folds increase the surface area at the motor endplate. 13) Force decreases at faster shortening velocities because there is less time for actin myosin bonding14) The muscle twitch is the response of a muscle to a single action potential on its motor neuron. Note the latent period, the period of contraction, and the period of relaxation on the myogram. 17) a constant tension produced by muscles for long periods of time.18) Able to go back to resting length23) Results in complete and incomplete tetanus.24) Fiber bundles25) Scientific study of human movement27) along Z lines, where only thin filaments are present29) 30) stimulus strength increases until strong enough to produce action potential; contraction33) Surrounds fascicles 34) 36)  - where thick and thin filaments overlap Across: 1) stimulus not strong enough; no action potential; no contraction4) 5) Muscle fatigue is the physiological inability to contract due to the shortage of available ATP 7) Ability to shorten9) The sliding filament model of muscle contraction states that during contraction, the thin filaments slide past the thick filaments11) Able to respond to a stimulus12) Smallest unit of contraction 15) A sacromerre is the distance between 2 Z lines16) 19) Protects and surround each muscle fiber20)  T tubules are infoldings of the sarcolemma that conduct electrical impulses from the surface of the cell to the terminal cisternae.21) 22) Striations are due to a repeating series of dark A bands (anisotropic, polarize visible light) and light I bands26) Creatine phosphate-Used to convert ADP to ATP by transfer of a high-energy phosphate group. A reserve high-energy compound28) 31) Oxygen debt is the extra oxygen needed to replenish oxygen reserves, glycogen stores, ATP and creatine phosphate reserves, as well as conversion of lactic acid to32) 35) The neuromuscular junction is a connection between an axon terminal and a muscle fiber where stimulation of the muscle cell to contract occurs.37) Blends into connective tissue between mucsles 38) ability to be stretched 39)  consists of one neuron and the muscle cells that it controls.
