What is any change in velocity during a given length time?
Acceleration is any change in velocity during a length of time.
What is the relationship between starting length and initial velocity of shortening?
The lighter the weight, the greater the initial velocity of shortening; inverse relationship.
What effect does shortening the length of the pendulum have on the period of the pendulum?
A shorter pendulum has a shorter period. A longer pendulum has a longer period.
What is a change in velocity in a certain amount of time called?
Acceleration is any change in velocity during a length of time.
What is the formula you use to dertermine acceleration?
Average acceleration during any period of time = (change in speed during that time) divided by (length of the time period).
What length decreases when sarcomere shortens?
I-bands
What are the 3 sections along the length of sarcomere?
The three sections along the length of a sarcomere are the A band, the I band, and the H zone. The A band is the dark region in the center of the sarcomere that contains both thick and thin filaments, while the I band is the light region at the ends of the sarcomere that contains thin filaments only. The H zone is the region in the center of the sarcomere where only thick filaments are present.
What is Huxley's Sliding Filament Theory?
The sliding filament theory is the explanation for how muscles produce force (or, usually, shorten). It explains that the thick and thin filaments within the sarcomere slide past one another, shortening the entire length of the sarcomere. In order to slide past one another, the myosin heads will interact with the actin filaments and, using ATP, bend to pull past the actin.
Do the you band and H zones become narrower during contraction?
Yes the H band shortens. During contraction the length of the sarcomere or from z line to z line must decrease in length. Thus the I band which is bisected by the z line must shorten as well as the H band, even though the H band is bisected by the A band it must shorten to allow fior this decrease in length. The A band does not shorten because it is composed of the entire length of myosin whose length never decreases during contraction.
Does actin filaments extend the enyire length of a sarcomere?
Yes, it makes cool stuff
What is any change in velocity during a given length time?
Acceleration is any change in velocity during a length of time.
Does muscle length change during isometric movements?
No, the length of the muscle fibers does not change. In isotonic movements is when the length changes.
What structure runs the length of the sarcomere through the thick filaments and contributes to the elastic recoil in muscle?
titin
What is name of music term meaning unsteady or free form beats?
When the conductor can change the length of the beat, elongating or shortening the duration of the note for effect?
Why does band stay the same length when the sarcomere shortens?
the A band stays the same length because it is the length of the myosin filaments, and all the myosin does it sit there while actin slides past it.
Why quail stop laying eggs?
Usual reason is the shortening day length, as the year progresses - poultry and game birds do not naturally lay during the winter. Also things such as a change of surroundings or being frightened by a predator can bring laying to a stop.
Does internode length change during growth?
Yes it does
