What happens when summation occurs in cardiac muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
Some muscle fibers always contracted?
Summation and/or tetanic contraction. Summation is increased muscle contraction until maximal sustained contraction is achieved. Tetanic contraction is sustained muscle contraction without relaxation. If you're inquiring for the Learning Objective Review in an anatomy and physiology course, the question refers to a condition in which some fibers are always contracted... so I'm not sure if they're looking for summation or tetanic contraction - but I think it would be tetanic contraction as summation is more the process leading up to the tetanic contraction...
When the frequency of stimulation of a muscle is great enough?
wave summation results and muscle twitches overlap.
What is the discussion about the physiology of muscle contraction?
muscle tone
What are the muscle proteins and their interaction in the muscle physiology?
Myoglobin and Actin
What is the state called where some of the fibers in particular muscle are always contracted?
summation
What is the primary function of wave summation?
produce smooth, continuous muscle contraction
Why is it important that summation not occur in heart muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
When does wave summation occurs?
Wave summation occurs when a muscle is stimulated rapidly enough that it does not have time to completely relax between stimuli, causing the contractions to combine or "summate" to produce a stronger muscle contraction. This phenomenon can occur during repetitive or sustained muscle activity, leading to increased muscle force production.
Is the force of muscle contraction controlled by multiple motor unit summation and recruitment?
True
What is the significance of the i band in muscle physiology?
The i band in muscle physiology is important because it contains the thin filaments made of actin. These filaments play a crucial role in muscle contraction by interacting with the thick filaments made of myosin. The i band shortens during muscle contraction, allowing the muscle to generate force and movement.
What is summation is anatomy?
Summation in anatomy refers to the process by which multiple individual muscle twitches are combined to produce a sustained contraction of a muscle. This phenomenon involves the additive effect of multiple stimuli on a muscle fiber. It is essential for generating smooth and coordinated movements in the body.
