What is the definition of graded drug response to chloroquine?
The intensity of effect increases with the dose or concentration of drug is termed a Graded response
In response to a muscle being overstretched a muscle spindle generates a somatic spinal reflex that ultimately causes what response?
Both contaction of the agonist muscle and relaxation of the antagonist muscle
What are some ways muscle contractions can graded?
Muscle contraction can be: Concentric, Eccentric, Static.
What is all or none response?
The generation of an action potential (AP) is generally considered a 'all or none' response as opposed to a graded response. This has to do mainly with single motor units. Once an AP is triggered in the neuron body (soma) the AP travels along the axon to the neuro-muscular junction where it releases acetylcholine (Ach). The muscle then either fires (if enough axons discharge) or not, but there is no halfway response.
What is the relationship between amplitude of muscle response and voltage of stimulus applied?
The relationship between the amplitude of muscle response and the voltage of the stimulus is generally linear. As the voltage of the stimulus increases, the muscle response increases in amplitude up to a certain point. Beyond that point, further increases in voltage may not significantly increase the muscle response amplitude or could lead to muscle fatigue or damage.
What is the premotor phase of reaction time?
The time it takes from recognizing a stimulus to the initiation of a muscle response (the muscle response can be recorded using an EMG).
What the reaction to a stimulus by a muscle gland?
A Response
How is the all-or-none response related to the strength of a muscle contraction?
The all-or-none response related to the strength of a muscle contraction is related to the idea that the muscle either contracts or it does not (it relaxes). There is no middle ground.
What kind of muscle cell contract?
Smooth muscle cells contract in response to fluid flow.
What is the all none law of muscle response?
all-or-none law is the principle that the strength by which a nerve or muscle fiber responds to a stimulus is not dependent on the strength of the stimulus. If the stimulus is any strength above threshold, the nerve or muscle fiber will give a complete response or otherwise no response at all
The structure that brings about response in the nervous system?
The effector such as a muscle or gland brings about response in the nervous system.
What are the smooth muscle cells that stand hairs on end in response to cold known as?
Arrector Pili Muscle
