What is the difference between wave summation and recruitment?
Wave summation releases more calcium and increases the force of contraction by increasing the firing rate of motor neurons (The second contraction takes place before the first is completely at rest) so each stimulation adds up. This is all within ONE MUSCLE FIBER. Recruitment is the calling up multiple MOTOR UNITS, in order to increase the force of contraction. t has a size principle (those with small diameters, the more delicate ones are called first, then the larger and so on.) There is no added calcium ions as in wave summation. They usually occur together. wave summation can cause tetanus, while recruitment cannot.
What is summation in muscle physiology?
In skeletal muscle contraction, summation means increasing the number of stimuli that is delivered to a given motor unit per time. This increases the Calcium concentration, which causes more tension and shortening of the muscles.
What must be present for muscle contraction to occur?
- Multiple Fibre Summation Related to the central nervous system sending signals to contract muscles. - Frequency summation Related to when action potentials sent to muscles synchronously. Check the related links below for more information.
What is multiple motor unit summation or recruitment in a muscle?
When a greater number of motor units are present in a muscle and are able to be simultaneously stimulated causing an increase in muscle force (Sherwood, and Kell 271-272).
What is the difference between summation and integration?
Integration is a special case of summation. Summation is the finite sum of multiple, fixed values. Integration is the limit of a summation as the number of elements approches infinity while a part of their respective value approaches zero.
What is the blood type in humans controlled by?
Blood types are controlled by multiple alleles.
What is muscle treppe?
•Increased contraction in response to multiple stimuli of same strength
Can a single trait controlled by multiple genes?
Yes
Can a single trait can be controlled by multiple genes.?
Yes
Why is blood type controlled by multiple alleles?
Yes.
What is summation is anatomy?
The process by which multiple or repeated stimuli can produce a response in a nerve, muscle, or other part that one stimulus alone cannot produce
What property of the synapse allow multiple stimuli to fire a neutron as a group of stimuli?
i am unsure of an exact answer, however i believe it to be "Summation"Summation:1: the act or process of forming a sum :addition2: sum, total3: cumulative action or effect ; especially: the process by which a sequence of stimuli that are individually inadequate to produce a response are cumulatively able to induce a nerve impulse.Source:http://www.merriam-webster.com/dictionary/summation
