Alterations in the nervous system firing pattern can occur as a result of training. Motor unit recruitment and the firing pattern to muscle can change with training also. The improvement in the firing pattern of nerves explains the initial improvement that occurs from strength training. Light exercise stimulates the recruitment of slow-twitch fibres whereas larger forces involved in things such as weight training recruit fast-twitch fibres. Please let me know if this helps- because that's what I wrote for my assignment!

How do diurnal variation affects body temperature?
during sleep, body metabolism slows down, as do muscle contractions. The body'stemperature is lowest in the morning before metabolism and muscle contractions begin increasing.
The muscle of the arm such as the biceps brachii have what innervation?
Musculocutaneous
What is The main effect of the warm up period of athletes as the muscle contractions increase in strength?
they warm up their muscles to avoid damaging them
Effect of sympathetic innervation to muscularis mucosa?
contraction of smooth muscle
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.
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.
What process involves muscle contractions that move food through the esophagus molecules?
Different types of muscle contractions
Why is Adductor magnus muscle considered as a hamstring muscle sometimes?
Due to its common embryonic origin and its innervation and action.
What is an Isotonic Contractions?
Isotonic contractions. This happens when the muscle shortens as it contracts
What wave summation results in stronger contractions at the same stimulus strength because the muscle doesn't have time to completely what between successive stimuli?
Relax
Does isotonic muscle contractions involve shortening of muscle?
Yes
What is recipricol innervation in human body?
Basically, as one muscle contracts, the antagonist relaxes
