What else can I help you with?
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.
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.
How does the contraction of the I band contribute to the overall function of skeletal muscle?
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
What movement does not increase or decrease the angle between bones?
Isometric contraction is a type of muscle movement that does not result in any change in the angle between bones. This type of contraction involves the muscle producing force without changing its length or causing movement at a joint.
What tissues cells shorten and exert force?
Muscle cells are the tissues that shorten and exert force. This is achieved through the sliding of actin and myosin filaments within the muscle fibers, causing them to contract and generate tension. This contraction allows muscles to exert force to produce movement or maintain posture.
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's an isometric contraction?
An isometric contraction is when the muscle does not shorten and no movement results.
Does the Z line shorten during muscle contraction?
Yes, the Z line shortens during muscle contraction.
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.
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 is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
What is the contraction phase?
The contraction phase refers to the stage of a muscle action where the muscle fibers shorten and generate force. This is when the muscle is actively contracting and pulling on the tendons to create movement.
How does the contraction of the I band contribute to the overall function of skeletal muscle?
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
A contraction in which a skeletal muscle does not shorten but its tension increases is called isometric?
An isometric contraction is the name given to a skeletal muscle that does not shorten, but increases tension. The muscles generate force to protect themselves.
