What else can I help you with?
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.
In a concentration contraction the muscles shorten to produce movement?
True.
What is a twitch contraction?
A twitch contraction is a single, brief contraction of a muscle fiber in response to a stimulus. It is the smallest unit of muscle contraction and is not strong enough to produce movement of a limb.
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.
Where is calcium stored in a relaxed skeletal muscle?
yes calcium is stored in muscles as it is necessary for muscle contraction and muscle contraction is very sensitive to the amount of calcium
What organelle would be most common in a muscle cell?
Mitochondria - to produce the ATP needed for muscle contraction
What is the minimal intensity of stimulation necessary to trigger a muscle contraction?
threshold stimulus
What is the process that takes place in a muscle cell to produce energy for it to work?
Contraction
What is the primary function of wave summation?
produce smooth, continuous muscle contraction
What is the type of contraction in which the muscle fibers produce increased tension but does not shorten?
An isometric contraction builds tension but there is no joint movement.
Why is ATP needed for muscle contraction?
ATP is needed for muscle contraction because it provides the energy necessary for the muscle fibers to contract and generate force. Without ATP, the muscle fibers would not be able to function properly and contract effectively.
What employs a parallel after discharge circuit to produce sustained muscle contraction?
a oscillating circuit
