a classically conditioned response
a direct, uncontrolled response to a stimulus
a fast, involuntary, unplanned sequence of actions that occurs in response to a particular stimulus
a fixed relationship between a stimulus and a response where the stimulus elicits the response
a movement that is performed involuntarily when a sensory nerve is stimulated, sending a signal to the spinal cord, which then signals a muscle to contract
an action that takes place automatically when something happens
an automatic activity which bypasses the brain

an inborn, automatic response to a particular form of stimulation, and they are the neonates most obvious organized patterns of behaviors
an integral reaction of the organism
an involuntary, automatic circuit designed to respond to external or internal changes in the body
an involuntary muscular response to a sensory
an involuntary reaction to stimuli such as touch, sound, and light
an involuntary response that occurs very rapidly
an involuntary response to stimuli
an involuntary, stereotypical reaction , whereas these responses by people with very short reaction times are voluntary movements adapted to particular situations
a pathway with an afferent signal (sensory) that evokes an efferent response (motor)
a reaction started by the environment acting as a stimulus upon some nerve which communicates the excitement thus started in itself to other nerves by means of its corfnexions with these in the central nervous organ
a reaction to some kind of stimulus (stroke, pin prick, etc
a relationship between a specific environmental event ( a stimulus , or S ) and a fixed behavioral action (a response , or R ) that it evokes
a relationship between a specific event and a simple response
a response of a specific body part (e
a simple form of behavior and clearly illustrates the logic of a sensory-motor system loop
a simple, inborn, automatic response by a part of the body to a stimulus
a specific, involuntary, unpremeditated response to a particular stimulus
a type of involuntary action
any response that occurs automatically without conscious effort.
A reaction, involuntary movement or response to a stimulus applied to the periphery and transmitted to the nerve centers in the brain or spinal cord.
Reflex usually describes an immediate involuntary response evoked by a stimulus, for example the cough reflex.
A reflex is a movement or activity of the body performed automatically and without conscious volition in consequence of activation of sensory neurons which transmit impulses toward the central nervous system, and which in turn activate motor axons which cause movements of muscles or glands. Reflexes may be purely somatic, purely autonomic or mixed somatic and autonomic.
A stereotyped (involuntary) motor response elicited by a defined stimulus
An involuntary motion resulting from a stimulus.
Involuntary movement elicited by activation of sensory receptors.
a simple unlearned stimulus-response link, such as salivating in response to food in one's mouth.
The action which results from the stimulation of sensory neurons, affecting efferent neurons, without the intermediation of consciousness. It is not essential that the action be unconscious, but only that consciousness, or volition, shall not affect the action.
an involuntary response - muscular or secretory - to a stimulus mediated by the central nervous system.
A response to a stimulus that occurs without conscious effort; one of the simplest forms of behavior.
An involuntary motor response to a sensory stimulus.
An involuntary action resulting from a stimulus.
Involuntary, predictable response to a particular stimulus.
Involuntary movement of a muscle after stimulation.
An automatic action, involving only a few neurons (in vertebrates, often in the spinal cord), in which a motor response swiftly follows a sensory stimulus.
An involuntary response to a stimulus involving nerves not under control of the brain.
An involuntary response of the nervous system to a stimulus, such as the stretch reflex which is elicited by tapping a tendon with a reflex hammer, or absent reflexes can be indicative of neurological damage, including MS, and are therefore tested as part of the standard neurological exam.
In general, muscle movement orchestrated by the nervous system in response to a stimulus and without conscious (voluntary) control; an example is the kneejerk reflex.
An involuntary and immediate response to a stimulus.
A simple, stereotyped reaction in response to some stimulus (e.g., limb flexion in withdrawal from pain).
A two-way paging and a transport protocol that provides message acknowledgement, customized replies and the downloading of data files to a computer. ReFLEX adds a response channel to a traditional one-way paging system, and ensures that voice mail messages will be received through its acknowledge-back capability.
A reaction that is involuntary. The corneal reflex is the blink that occurs with irritation of the eye. The nasal reflex is a sneeze. See the entire definition of Reflex
An involuntary response to stimulation by the body.
A type of involuntary response.
an involuntary response to a specific stimulus
An automatic, involuntary response of the body to a trigger, e.g., blinking when an object moves too close to the eye, or moving a hand away from a hot object. It involves a simple pathway of nerve impulses. The brain is not necessarily conscious of the response that has taken place.
An automatic response to a stimulus.
An involuntary response of a certain part of the human body to a brief stimulus which usually does not require processing of the stimulus through the conscious mind. Example: jerking of leg upon striking the knee (patellar) tendon.
A reflex is an involuntary reaction to a stimulus. The "knee-jerk" reflex is a common example of a neuromuscular reflex used in medical assessment. However, Edgar Cayce (and the osteopathic physicians of his era) were also interested in more subtle kinds of reflexes which occur between the nerve centers within the body. Many readings described such reflexes as the cause of imbalance in the body, resulting in disease. Traditionally, osteopathic physicians utilized reflexes in the body as part of their therapeutic techniques aimed at assisting the body to heal itself.
An involuntary movement in response to stimulation such as touch, pressure, or joint movement.
Involuntary movement in response to touch, light, sound, or other form of stimulation; controlled by subcortical neural mechanisms.
Contraction of a muscle in response to tapping the tendon or guider with a reflex hammer; it requires intact sensory nerve supply to transmit the stretching of receptors in the muscle, and intact motor nerve supply for the muscle to contract.
