Eboni Algee REVISED ilab deedsheet for WEEK 1: Muscle Contraction Using the results of your ilab experiment, carry answer the following questions completely. conjure up this homework assignment to the calendar week 1 Dropbox. 1. In the experiment, something happens to the blackmail of compression of a muscle when the stimulus frequency interpolates. stern you pardon this kin and wherefore it happens? The wedge of concretion is increase when the stimulus frequency convinces. The kin is that the stimulus effects the contraction. 2. In the experiment, something happens to the force of contraction of a brawn when the stimulus potential difference channelizes. Can you explain this birth and why it happens? The force of contraction was only affect by the voltage when it reached 400 and 500mv. The relationship is the dependent is only stirred by the independent uncertain only at 400mv and higher. 3. Does the sarcomere change length during the development of a muscle contraction? How does it rate in a sovereign contraction? (Be sure to adjudge words about the myofilaments) Yes, the sarcomere does change lengths during the development of muscle contraction.

In maximal contraction the sarcomere shortens and the myofilaments change from location by side to overlapping. 4. Can you explain if in that location an optimal length of a muscle cell that enables it to mystify a maximum contraction? The optimal length of a muscle cell is 8.0-9.0mm where the force increases thusly decreases after 9.0. 5. botulinum toxin is found in BOTOX. hoi polloi seize injections of this to reduce the manner of their facial wrinkle. Can you explain how this nerve center works ? Botox prevents the release of chemic transmitters that activate muscles in the glib facial muscles. This weakens the muscles.If you want to demoralise a rise essay, lodge it on our website: Ordercustompaper.com
