3 neurons are included in the reflex arc. They are:
Afferent neurons (take the message to the spinal cord) (sensory)
Association neurons (directs message to the efferent neuron and the brain) (report reflex to the brain)
Efferent neurons (takes message to effector) (motor)
Not all reflexes have interneurons.

What kind of reflex uses just two neurons?
monosynaptic reflex arcs
A knee-jerk reflex employs motor neurons and what?
it employs sensory and motor neurons
In a three neuron reflex arc the afferent neurons synapse with?
The afferent neurons synapse with the interneuron.
What is the name given to reflexes that involve more than 2 neurons?
polysnaptic reflex
What are the three types of neurone involved in a reflex action?
The three types of neurons are sensory(afferant) neurons, interneurons, and motor(efferant) neurons. Sensory, or afferent, neurons send information from the receptor to the central nervouse system. Interneurons, found only in the central nervous system, play the role of interpretting the impulse. The motor, or efferent, neurons send the information from the central nervous system to the effector. Receptor->sensory neuron->interneuron->motor neuron->effector.
What is the absolute minimum number of neurons that can be involved in a reflex?
A minimum of 3 neurons.
What will cause the reaction time of a reflex to increase?
a large number of neurons-therefore, synapses-involved
What Three kinds of neutrons that would be involved in a reflex impulse?
They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.
What are three kinds of neutrons that would be involved in a reflex impulse?
They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.
What connects to sensory neurons?
You have three neurons in the reflex arc. You have the afferent, the intermediate and efferent neurons in the reflex arc. So the answer is intermediate neuron.
Is an ankle jerk reflex somatic or autonomic?
Ankle jerk is somatic. It is the reflex action, in which the afferent. connecting and the efferent neurons are involved. Autonomic nerves do not supply the striated muscles.
What kind of reflex has only two neurons?
monsynaptic reflex arcs
What kind of reflex uses just two neurons?
monosynaptic reflex arcs
Does visceral reflex arcs have two sensory neurons?
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
A knee-jerk reflex employs motor neurons and what?
it employs sensory and motor neurons
A withdrawal reflex employs what neurons?
Withdrawal reflex or flexor reflex employs sensory neuron, interneuron and motor neuron.
What reflex has at least one interneuron placed between the sensory and motor neurons?
Polysynaptic Reflex
