What is the system's reaction to the stimulus?
Stimulus detected by receptors, transmitted to brain via afferent neurones, info processed at brain, efferent neurones, then to affector such as muscles.
How is the brain informed that a receptor is adapting to a stimulus?
The amplitude of the generator potential or the frequency discharge of the sensory fiber decreases.
What is the sensory neuron function?
Sensory information is transmitted by the sensory neurons. They are nerve cells that convey data to spinal cord and brain.
Which neurons decide about the action for a certain stimulus?
Sensory neuron
What is the connection between sensory nerves and the neurons in the brain?
Sensory nerves transmit information from sensory receptors in the body to the neurons in the brain. When sensory receptors detect stimuli such as touch, temperature, or pain, they send signals through sensory nerves to the brain. Neurons in the brain then process and interpret these signals, allowing us to perceive and respond to the sensory information.
What is the system's reaction to the stimulus?
Stimulus detected by receptors, transmitted to brain via afferent neurones, info processed at brain, efferent neurones, then to affector such as muscles.
What are the two pathways by which messages are transmitted?
1 sensory organ - sensory nerves - spinal cord - brain 2 brain - motor nerves - spinal cord - muscles
A reflex arc begins with the stimulation of a what?
A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
How is the brain informed that a receptor is adapting to a stimulus?
The amplitude of the generator potential or the frequency discharge of the sensory fiber decreases.
What is the sensory neuron function?
Sensory information is transmitted by the sensory neurons. They are nerve cells that convey data to spinal cord and brain.
What does your body do reaction to a stimulus?
A Stimulus is picked up by a receptor, travels along a sensory neurone to either the spinal cord or brain, then it is processed to produce some response.
How does information from the sensory receptorsin the skin get to the brain?
The initial sensory receptor detects a change e.g temperature. This is sent as an electrical impulse via a series of sensory receptors to the spine, if there is a problem a reflex occurs. If there is no problem the impulse is transmitted to the brain through the spinal cord.
What part of the brain receives messages?
ThalamusIf you are referring to outside stimulus that are sensory messages, all stimuli, except smell, go to the thalamus in the brain which is then relayed to the cerebral cortex.
What are the very first of the three steps basic to all sensory systems?
1. Recieve stimulus 2. Transform stimulus 3. Deliver stimulus
Which neurons decide about the action for a certain stimulus?
Sensory neuron
How do the three types of neurons work together to produce a response to an environmental stimulus?
They are sensory input, integration, and motor output. It sends signals to the brain.
What part of the nervous system would be responsible for moving your hand from a burner?
A reflex is a rapid, involuntary response to a stimulus. Most reflexes are spinal reflexes with pathways that traverse only the spinal cord. During a spinal reflex, information may be transmitted to the brain, but it is the spinal cord, and not the brain, that is responsible for the integration of sensory information and a response transmitted to motor neurons. If you touch a very hot burner, your hand will move away faster than information goes to your brain to tell you "Hey, that is hot!"
