Document Summary
Look for dicrotic notch (closing of aortic valve) Aliasing - sampling produces signal that does not resemble analog signal. Frequency - how many cycles per unit time. According to the nyquist rate, you should sample at greater than twice the frequency of your signal (s>2f) High-pass filters remove low frequency signals (i. e. only higher frequencies may pass) Notch filter is used to eliminate the line frequency and is usually printed on the. Excitability - ability to respond to a stimulus. Elasticity - ability of muscle fibers to recoil to resting length after they finish contracting. Stimulus provided by excitation of motor nerve resulting in the release of the neurotransmitter, acetylcholine (ach) Muscle is made up of individual muscle fibers organized in fascicles. Each individual fiber is innervated by a branch of a motor axon. Neuronal action potential activates all of the muscle fibers. Motor unit - motor neuron and all the individual fibers it innervates.
