What system is responsible for stimulus and response?
The nervous system has three main functions: gathering sensory information from external stimuli, synthesizing that information, and responding to those stimuli.
What part of the nervous system is responsible for the stimuli process?
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception.
Do neurons respond to a stimulus?
Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). The nucleus of a neuron is located in the cell body. Extending out from the cell body are processes called dendrites and axons.
How the nervous system receives processes and responds to a stimulus?
Receptors are groups of specialised cells. They detect a change in the environment (stimulus). In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
What branch of the nervous system controls this response?
The sympathetic division of the autonomic nervous system regulates the flight-or-fight responses.
How does the nervous system help us respond?
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
What is a stimulus response pathway?
The basic pathway for a nerve impulse is described by the stimulus response model. A stimulus is a change in the environment (either external or internal) that is detected by a receptor. Receptors transform environmental stimuli into electrical nerve impulses.
What is stimulus response reinforcement?
When a particular Stimulus-Response (S-R) pattern is reinforced (rewarded), the individual is conditioned to respond. Reinforcement is the key element in Skinner’s S-R theory. A reinforcer is anything that strengthens the desired response.
What is the sympathetic response?
The sympathetic nervous system directs the body’s rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body’s alertness and heart rate, sending extra blood to the muscles.
How does the nervous system respond to stimuli?
In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli. Click to see full answer.
What is the function of the receptors in the nervous system?
Receptors are groups of specialised cells. They detect a change in the environment (stimulus). In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
What is a stimulus in psychology?
A stimulus is a change in the environment (either external or internal) that is detected by a receptor. Receptors transform environmental stimuli into electrical nerve impulses. These impulses are then transmitted via neurons to the central nervous system where decision-making occurs.
How does the sympathetic nervous system react to stress?
More dramatic stress states such as physical injury or severe infection are very potent stimuli for activation of the sympathetic nervous system and of adrenaline secretion from the adrenal medulla. The stimuli reaching the brain are multiple.
