Smooth graded contractions of skeletal muscle are produced through the recruitment of motor units and the varying frequency of action potentials. When a muscle is stimulated, not all motor units are activated simultaneously; instead, smaller units are recruited first, allowing for finer control. Additionally, increased frequency of nerve impulses leads to tetanus, where successive contractions fuse, resulting in a smoother and more sustained force. This combination of recruitment and frequency modulation allows for smooth and precise muscle movements.
What else can I help you with?
What are some ways muscle contractions can graded?
Muscle contraction can be: Concentric, Eccentric, Static.
What is a graded muscle response?
It is the variation of stimulation needed in skeletal muscle contraction in order to have controlled movement.
What can occur when the effects of one graded potential are added onto the effects produced by another graded potential which can lead to an action potential.?
More sodium ions pile up (accumulate) at the axon hillock from the combination of the two (or more) graded potentials, which may be then be sufficient to initiate the action potential.

What is the difference between step graded and linearly graded semiconductor p-n junction?
In step-graded the acceptor and donor concentrations in the semiconductor are constants up to the junction.In a linearly-graded junction, impurity concentration varies linearly with distance from the junction
When was Mooresville Graded School District created?
Mooresville Graded School District was created in 1905.
What is Mooresville Graded School District's motto?
The motto of Mooresville Graded School District is 'iBelieve, iCan, iWill'.
Graded potentials will not be initiated by?
Graded potentials will not be initiated by hyperpolarization. Graded potentials are subthreshold changes in membrane potential that can depolarize or hyperpolarize a cell, but they are typically initiated by a stimulus, such as neurotransmitter binding or sensory input. Hyperpolarization alone may not be strong enough to reach the threshold for generating a graded potential.
Why is timber graded?
Understanding lumber grades will help ensure you meet design expectations. Structural framing products are graded for their strength and other physical properties, as opposed to appearance products, which are graded for their aesthetic properties.
