Constant contraction of a muscle is?
constant contraction of a muscle is called the muscle tone
Inability of muscle fibers to contract after a long period of contraction?
muscle fatigue
When a person works out to gain muscle are they adding more muscle fibers?
No, the number of fibers remains constant. The size of the fibers increases.
What is the maximum rate of contraction in normal cardiac muscle fibers?
What_is_the_maximum_rate_of_contraction_in_normal_cardiac_muscle_fibers
What is recruitment anatomy?
Increasing the number of muscle fibers involved in the contraction.
What is recruitment in anatomy?
Increasing the number of muscle fibers involved in the contraction.
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.
Explain a muscle spasm in terms of recruitment of muscle fibers?
A muscle spasm is the spontaneous recruitment of muscle fibers. The resulting contraction is usually painful, but it typically resolves very quickly.
What is called a constant muscle contraction?
Tonus is the continous baseline muscle tone in the body.
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.
The Ca2 that is required for sustained contraction of smooth muscle fibers comes mainly from the?
extracellular fluid surrounding the fibers
Is it true or false that all of the muscle fibers involved in a muscle contraction are performing individual muscle twitches?
falso my friendo
