Equation 8.7 is being used to solve a problem in rotational kinematics. Which one of the following sets of values for the variables 0, , and t cannot be substituted directly into this equation to calculate a value for ? (a) 0 1.0 rad/s, 1.8 rad/s2 , and t 3.8 s (b) 0 0.16 rev/s, 1.8 rad/s2 , and t 3.8 s (c) 0 0.16 rev/s, 0.29 rev/s2 , and t 3.8 s ( 0t
Lecture objectives 16 1. Describe and identify the components of the motor unit A single motor neuron + fibers it controls = a motor unit 2. Describe the components of a muscle twitch Muscle twitch - a motor unit's response to a single action potential from the motor neuron Latent Period - first few milliseconds, excitation - contraction coupling starts, cross bridges formed but no measurable shortening Contraction Period - 10-100 ms, cross bridges active, reach peak of muscle tension, muscles may shorten Relaxation Period - 10-100 ms, initiated by Ca2+ re entry into the SR, decreased number of active cross bridges, muscle tension decreased to zero, muscle returns to initial length 3. What is muscle tension How is the difference from muscle tone Muscle tens
