Single muscle contraction that lasts only a fraction of a second is called?
A: A Twitch
At what rate in muscle contraction does a single myosin head consumes?
5 ATP per second
Does a muscle contract the instant it is stimulated?
no, the muscle does not begin to contract the instant it is stimulated, rather a fraction of a second later!
A muscle is stimulated and exhibits a contraction twitch Before this twitch is over it is stimulated again and a second twitch occurs piggyback on the first one and causes a higher contraction?
summation
Factors influencing force generation?
· First- the type and number of muscle fibers · Second- the initial length of muscle at time of contraction · Third- the nature of the neural stimulation
What is a fraction of a minute called?
Second
What is second stimulus before relaxation causes increased force called?
Contraction phase
What is contraction period?
Period of Contraction is the second stage of a muscle twitch, when cross bridges are active, from the onset to the peak of tension development, and the myogram tracing rises to a peak. This period lasts 10-100 ms. If the tension (pull) becomes great enough to overcome the resistance of a load, the muscle shortens
What is the difference between myoclonus and clonic spasm?
Myoclonic seizures involve an extremely brief (< 0.1 second) muscle contraction and can result in jerky movements of muscles or muscle groups.Clonic seizures are myoclonus that are regularly repeating at a rate typically of 2-3 per second
Do Every muscle fiber has several motor end plates that neurons attach to yes or no?
Muscle fibres are connected to neurones on either a 1:1 ratio (such as fingers, where precise muscle control is needed) whereas some muscle fibres are connected to neurones in a 1 neurone:several muscle fibres ratio. The second occurs where precise movement is not needed, such as the calf muscle, where a stimulus needs to cause a large and synchronised contraction of muscles as opposed to precise contraction of certain individual fibres.
What is the second name for heart?
Another name for the human heart is a cardiac muscle.
What is the term for cardiac contraction recovery?
i did not understand your question well, but there are three wave in working heart i a second: 1-P wave:its about 0.1 second and contraction of the Atriums 2-QRS wave: its about 0.4 second and contraction of the bellies. 3-T wave:its about 0.5 second and relaxing of the heart..
