The strongest muscle contractions are normally achieved by?
Increasing stimulation up to the maximal stimulus
The strongest muscle contractions are normally achieved by what?
The strongest muscle contractions are normally achieved by increasing the stimulation up to the maximal stimulus. There are various classifications of contractions, including eccentric and concentric.
Why dont your eyes adapt completely to a repeated visual stimulus?
Our eyes adapt completely to repeated visual stimulus because
How is wave summation achieved in vivo?
simply: Wave summation occurs when a second stimulus is applied before relaxation occurs completely. In depth: In order for a muscle to contract electrical shock or nerve impulse must cause voltage-sensitive tubule proteins (T-tubules) of sarcoplasmic reticulum to change shape and allow Ca2+ into cytosol. Ca2+ binds to troponin (changing its shape) allowing myosin (makes thick filaments) to attach to actin ( makes thin filaments). Myosin pulls itself along actin via ATP hydrolysis, this is called a cross bridge cycle, basically shortening of muscle. Before the contraction stops, another stimulus is sent to the muscle allowing more Ca2+ into the cytosol which keeps allowing cross bridge cycle. wave summation means the contractions are added together. thus increasing the force of the second stimuli. force will increase until the muscle reaches its threshold.
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
How might a person exhibit positive feedback communication?
Positive feedback increases the original stimulus. An example is labor contractions. The initial contraction signals the body to release hormones that increase the frequency and intensity of subsequent contractions.
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.
If a second stimulus arrives before the relaxation phase has ended a second more powerful contraction occurs this is called what?
In fact it is not treppe it is wave summation. 4th year bio med! I KNOW MY STUFF!!
Signal to which an organism responds?
stimulus
How do you spell stimulus?
'Stimulus' is the correct spelling.
What is the different between an external stimulus and an internal stimulus?
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
What are the four characteristics of a stimulus in stimulus coding?
The characteristics are modality (type of stimulus), intensity (strength of stimulus), duration (length of stimulus), and location (where the stimulus occurred).
