Mechanoreception, ability of an animal to detect and respond to certain kinds of stimuli—notably touch, sound, and changes in pressure or posture—in its environment. Sensitivity to mechanical stimuli is a common endowment among animals. In addition to
While the free nerve endings present in the epidermis pick up the noxious stimuli. The adaptive and conductive speeds of these receptors vary and eventually define the response of the body to any stimuli.Diseases Of The Integumentary System
pain, complex experience consisting of a physiological and a psychological response to a noxious stimulus. Pain is a warning mechanism that protects an organism by influencing it to withdraw from harmful stimuli; it is primarily associated with injury or the threat of injury. Pain is subjective and...
or avoid painful or noxious stimuli. There are several types of conditioning schedules. Continuous reinforcement schedules provide a reinforcement for every correct response, whileintermittentreinforcement schedules reinforce some responses but not others. There are several variations of the intermittent ...
This article begins with a discussion of the general features of nervous systems—that is, their function of responding to stimuli and the rather uniform electrochemical processes by which they generate a response. Following that is a discussion of the various types of nervous systems, from the si...
Reflex, in biology, an action consisting of comparatively simple segments of behaviour that usually occur as direct and immediate responses to particular stimuli uniquely correlated with them. Many reflexes of placental mammals appear to be innate. They
