Muscle

LAB ONE: Skeletal Muscle Physiology Your appointment is to change state agent the following questions after completing the lab. Submit your assignment to the calendar workweek 1 Dropbox by no subsequently than Sunday, end of week 1, 11:59 P.M. (MT). 1. mark lockjaw (6 points) Tetanus is a continuous densification of sinew. In bring to pass lockjaw, higher stimulant frequency eliminates the relaxation phase. Incomplete tetanus occurs when the tendon is at almost peak latent aggressiveness during rapid cycles between compression and relaxation. Its also a disease where sustained and effective contractions of skeletal muscles are randy by the action of a bacterial toxin. 2. deposit degenerate (6 points) When active skeletal muscle can no monthlong continue to perform at the required level of activity. 3. Define isometrical contractions (6 points) A contraction where the muscle doesnt shorten, just now its internal tension increases. 4. Define isotonic contractions (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 atomic number 20 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 terminal figure maximal remark. (6 points) The stimulus where departure beyond will not further increa se in force. 8. What has happened in the ! muscle when maximal stimulus is achieved? (6 points) All the person nerve fibers have been stimulated and responding all or none. 9. What is the divergency between stimulus lastingness 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 near essay, order it on our website: OrderCustomPaper.com
