What is the order of impulse conduction thru reflex arc?

Answer 1

A reflex is an automatic response, that protects the organism from a harmful stimulus. The receptors detect a stimulus which generates a nerve impulse along the sensory neurone to the Central Nervous System (CNS). The CNS decides the appropiate response to the stimulus. The nerve impulse then travels across a synapse to the relay neurone, across another synapse to the motor neurone to the effector. This is normally a muscle or an organ which moves or responds to bring about a response appropiate to the stimulus.

Answer 2

the signal starts at the Receptor

then to the sensory neuron dendrite

then to the sensory neuron cell body

then to the sensory region axon

then to the synapse of the sendory and internueron

then to the interneuron cell body

then to the interneuron axon

then to the synapse interneuron to motor neuron

then to the motor neuron axon

finishing at the effector

Answer 3

You start with the receptor which could be an eye if the stimulus is light. An electrical impulse then travels along a sensory neurone to the spinal cord. Chemicals diffuse across a synapse which is a gap, the electrical impulse is then passed along a relay neurone then to a motor neurone and to the effector to bring about a response.

Answer 4

receptor, sensory neuron, interneuron, motor neuron, effector

Answer 5

an impulse follows a path called as reflex arch pathway.
