What else can I help you with?
Which of the following would be recruited later in muscle stimulation when contractile strength increases?
Um are you an idiot, you never put choices! A) large motor units with small, highly excitable neurons B) motor units with the longest muscle fibers C) many small motor units with the ability to stimulate other motor units D) motor units with larger, less excitable neurons
Why does varying stimulus strength affects the twitch force?
Varying stimulus strength affects twitch force because it determines the number of motor units that are recruited to contract the muscle fibers. As the stimulus strength increases, more motor units are recruited, leading to greater force production. Conversely, lower stimulus strength recruits fewer motor units and results in weaker contractions.
What causes vagal escape?
when cardiac muscle begins to contract after a brief period of rest after vagal stimulation its initial strength of contraction increases to a plateau by staircase effect strong vagal stimulation of heart can stop heart beat for few seconds
What does Fly Ash do to the strength of concrete?
Increases the strength of concrete.It fill the pores in concrete thus strength is increases.It is fine particle hence bonding capacity increases thus strength is increases.
How does the frequency of stimulation affect the amount of force generated by the muscle?
Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
What is the relationship between the load on a muscle and its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
What is the Relationship between a load on a muscle its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
How does Curing of concrete affect its design strength?
It increases its strength, generally speaking.
What increases as the electronegativity diffference?
The strength of the bond.
How does the strength of a magnet's force change as it increases in size or proximity to an object?
The strength of a magnet's force increases as the magnet gets larger or closer to an object.
Stimulation of which would cause an increase in heart rate and contraction strength?
beta 1 receptors
The minimal strength of stimulation needed to elicit a muscle contraction is called the threshold stimulus?
true
