Submit your assignment to the calendar workweek 1 Dropbox by no later on than Sunday, end of week 1, 11:59 P.M. (MT). 1. mark lockjaw (6 points) Tetanus is a continuous densification of sinew. In realized tetanus, higher stimulant frequency eliminates the relaxation phase. Incomplete tetanus occurs when the energy is at almost peak latent abhorrence during rapid cycles between compression and relaxation. Its also a disease where sustained and effective condensings of skeletal muscles are bear on by the action of a bacterial toxin. 2. sterilise fag out (6 points) When active skeletal muscle can no daylong continue to perform at the required level of activity. 3. Define isometrical contractions (6 points) A contraction where the muscle doesnt shorten, besides its internal tension increases. 4. Define isotonic cont ractions (6 points) A contraction in which muscle tension remains constant at a given correlative angle and load and the muscle shortens. 5. What could be a chemic cause of fatigue? (6 points) A decline in pH within the muscle, decreasing calcium ion binding to troponin and altering enzyme activities. 6. What is the draw variable in an isometric contraction?

(6 points) Muscle space; it doesnt change in isometric contraction and it does in isotonic contractions. 7. Define the end point supreme arousal. (6 points) The stimulus where departure beyond will non further increase in force. 8. What ha s happened in the muscle when maximal stimul! us is achieved? (6 points) All the person nerve fibers have been stirred up and responding all or none. 9. What is the divergency between stimulus book and stimulus frequency? (6 points) relative frequency refers to how often stimulus is applied where intensity increases the force of a stimulus 10. At the threshold stimulus, sodium ions start to move into the cellphone or out of cell to...If you want to get a full(a) essay, order it on our website: BestEssayCheap.com
