Stimulus Anatomy Definition

A stimulus can be internal or external. A stimulus that is just strong enough to evoke a response.

14 1 Sensory Perception Anatomy And Physiology

A conditioned stimulus is a substitute stimulus that triggers the same response in an organism as an unconditioned stimulus.

Force of duration of contraction vary in response to stimuli of different frequencies and intensities. Aversive stimulus one which when applied following the occurrence of a response decreases the strength of that response on later occurrences. Sense organs such as the ear and sensory receptors such as those in the skin are sensitive to external stimuli such as sound and touch.

Specialized to respond to changes in their environment stimuli activation results in graded potentials that trigger nerve impulses sensationawareness of stimulus and perception interpretation of the meaning of stimulus occur in the brain. A supra maximal stimulus intensity mean supra maximal intensity53 or 11 ma range35 to 66 ma n8 was used which was 20 higher than the intensity used to produce a twitch of maximum amplitude in a relaxed muscle. 2 physiology that which influences or causes a temporary increase of physiological activity or response in the whole organism or in any of its parts.

In physiology a stimulus plural stimuli or stimuluses is a detectable change in the physical or chemical structure of an organisms internal or external environment. Contraction doesnt always shorten a muscle. 1 physiology a detectable change in the internal or external environment.

The ability of an organism or organ to respond to external stimuli is called sensitivity. Contraction produces tension the force exerted on the load or object to be moved. Adequate stimulus a stimulus of the specific form of energy to which a given receptor is sensitive.

Same principles apply to contraction of a single fiber and a whole muscle. Plural stimuli stĭmyə lī physiology something that can elicit or evoke a physiological response in a cell a tissue or an organism.
