Multiple fiber summation
WebWhen multiple electrical stimuli are applied to a muscle at a sufficiently high frequency, twitches merge into higher force contractions, a process referred to as summation. … WebWave summation occurs in the body when muscle fibers are stimulated before they have had a chance to completely relax What is the difference between stimulus intensity and stimulus frequency? Stimulus intensity is the electrical changes that relate to AP. Frequency is the number of AP per minute

WebThere are no multiple fibers precisely in the case that t-Kl is a pencil, in which case f has a section. PROOF. Since B is FD1, all fibers are linearly equivalent. By the Bombieri-Mumford formula [B-M, Theorem 2] for K we have (*) K -F + (mi-1)Fi where F is any fiber and the sum is over the multiple fibers {miFi} of f, the WebMultiple Fiber Summation – When a weak signal is sent by the CNS to contract a muscle, the smaller motor units, being more excitable than the larger ones, are stimulated first. As the strength of the signal increases, more motor units are excited in addition to larger ones, with the largest motor units having as much as 50 times the ...
Web1 Answer. Sorted by: 227. You can use \substack: If this is desired in inline math you can use \limits to obtain the limits underneath the summation symbol: However this is not recommended as it may not look good depending on how much adjacent text there is as it will affect interline spacing. WebMultiple fiber summation When a weak signal is sent by the central nervous system to contract a muscle, the smaller motor units, being more excitable than the larger ones, are stimulated first. As the strength of the signal increases, more …
WebNeurons receive multiple excitatory and inhibitory inputs. C, Temporal summation occurs when a series of subthreshold EPSPs in one excitatory fiber produce an AP in the postsynaptic cell. This occurs because the EPSPs are superimposed on each other temporally before the local region of membrane has completely returned to its resting state. WebThe amplitude of the EMG potentials becomes larger when more fibers within the muscle are activated (fiber summation), because of summation of the IR voltage drops …
WebMultiple fiber summation As the strength of the signal increases, larger and larger motor units begin to be excited. This is called the size principle and allows the gradation of muscle force. The force starts with weak contraction and becomes progressively greater when large amounts of force are required.
