What else can I help you with?
Does the Z line shorten during muscle contraction?
Yes, the Z line shortens during muscle contraction.
What happens to the Z line during muscle contraction?
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
What type of contraction in which the muscle fibers do not shorten are called?
If the muscle can not shorten because the muscle is trying to move a load that is greater than the force, then the contraction is isometric.
In a concentration contraction the muscles shorten to produce movement?
True.
What type of muscle contraction will shorten a muscle and decrease the angle between two bones?
Concentric muscle contraction will shorten a muscle and decrease the angle between two bones. This type of contraction involves the muscle generating force as it shortens to move a body part.
During muscle contraction the moves toward the?
During muscle contraction, the Z-lines move closer together as the sarcomeres shorten. This is due to the sliding of actin and myosin filaments past each other, resulting in the contraction of the muscle.
what's an isometric contraction?
An isometric contraction is when the muscle does not shorten and no movement results.
What change occur in sacomere during muscle contraction?
The sarcomere itself will become shorter.The sarcomere will shorten.
What is a concentric contraction?
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
What is the type of muscle contraction that produces movement in a joint and allows the muscle to shorten?
By tensing.
A contraction that causes a muscle to lengthen rather than shorten is called?
An eccentric contraction is one that causes a muscle to lengthen.
If a muscle contracts and its fibers shorten is the contraction isometric?
No! It is isotonic. But if the muscle contracts and the fibers do not shorten because the load is greater than the force applied to it, it is isometric.
