what is relay neuron???...?

Question

(in reflex action)
sensory neuron are those which carry information from the receptors to the spinal cord
motor neurons are those which carry information from the spinal cord to the effectors
what is relay neuron??

please explain in simple language and thanks for your time

Answer 1

An interneuron (also called relay neuron,association neuron or bipolar neuron) is a term used to describe a neuron which has two different common meanings.


According to the PNS definition, the neurons of the central nervous system, including the brain, are all interneurons. However, in the CNS, the term interneurons is also used for the general group of small, locally projecting neurons of the central nervous system. These neurons are typically inhibitory, and use the neurotransmitter GABA. However, excitatory interneurons also exist.

One example of interneurons are inhibitory interneurons in the neocortex which selectively inhibit sections of the thalamus based on synaptic input both from other parts of the neocortex and from the thalamus itself. This is theorized to help focus higher attention on relevant sensory input and help block out behavioraly irrelevant or unchanging input, such as the sensation of the backs of your thighs on a chair. A human brain contains about 100 billion interneurons.

Sorry but i use wikipedia here:

I think its easy lang.

Answer 2

Relay Neuron

Answer 3

1. Sensor neurones detect a stimulus. 2. The information is carried through the sensory neurone to the central nervous system. 3. The information is processed by your brain if there is no reflex action. 4. A response is carried by the motor neurone to the effector (muscle that acts). If there is a reflex involved, the information doesn't reach your brain but is processed lower down in your central nervous system for a quicker reaction, the relay neurone provides a link to get the information processed quicker. There are synapses between neurones, where the signal temporarily changes from electrical to chemical, then back again, in order to cross the gap between two neurones. Hope this helped :)

Answer 4

A relay neuron also known as interneuron,intermediary neuron or association neuron is the neuron that connects the sensory neuron to the motor neuron thereby transmitting impulses

Answer 5

A relay neuron (inter-neuron) connects the sensory neuron to the motor neuron. It 'relays' the input from the sensory neuron to create output from the motor neuron.

Answer 7

RELAY NEURONS ARE FOUND IN THE SPINAL CORD AND HELP DURING REFLEX ACTION.
THEY MAINLY HELP IN CONVERTING SENSORY NEURONS TO MOTOR NEURONS.
