Results A left gastrocnemius muscle of a frog (L=3.2cm in situ) was used in experiment 1 and 2‚ while a right gastrocnemius muscle of a frog (L=3.4cm in situ) was used in experiment 3. The sciatic nerve of the frog was placed over the stimulatory electrodes covered with a piece of a Kimwipe moistened with Ringer’s solution. The relationship between muscle length‚ force production and velocity of contraction was studied. Force transduced calibration In order to get a more accurate data from force

Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1. _Energize the power stroke of the myosin cross bridge. 2. _Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke. 3. _Energizing the calcium ion pump. 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called hydrolysis. Write the end products of this process: ATP (+ H2O) (

Reyes November 08‚ 2011 Dr. Dunaway Neuronal signaling in muscle contraction is triggered when an action potential reaches the neuromuscular junction. At this junction‚ acetylcholine (ACh) is the main neurotransmitter. Packaged in vesicles‚ ACh fuses with the neuron’s membrane and is released into the synaptic cleft. ACh diffuses toward the motor end plate and bind to the neurotransmitter receptor on it. The muscle fiber is then triggered to produce an action potential of its own that spreads

Case Analysis: Optical Fiber Corporation Introduction Optical Fiber Corporation (OFC) is a financially successful‚ albeit relatively small manufacturer of multimode optical fibers. The company was founded in 1990. The founders were able to enter the market largely on the basis of acquiring patent licenses from larger optical fiber firms. These licenses restricted competition between the entities and provided OFC with instant access to optical fiber technology. In return‚ OFC’s customer

Muscle Fatigue By Jaclyn Mullick B.S. The onset of muscle fatigue has hindered many athletes from achieving their maximum performance. Over the years we have been taught that it is the build-up of lactic acid that is the downfall of muscle fatigue and soreness. This is only partially true; there is a little more to it than what we have been told. I hope that this article provides you with a possible short-term remedy and does not confuse you more but rather makes you more aware
