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 neurons are involved in a reflex?
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 is the sequence of events in a typical reflex arc?
receptor detects a stimulus - change in the environmentsensory neurone sends signal to relay neuronemotor neurone sends signal to effectoreffector produces a response
Where do reflex actions occur?
Reflex action means a reaction you have given involuntarily. If you touch the immensely painful object, the touching hand or foot is removed away with out your knowledge. Here three neurons are involved. 1) Afferent 2) In the spinal cord 3) Efferent. This is called as reflex arc. Simultaneously information goes to higher centers and you notice the the problem, later on. So reflex action occurs at the level of spinal cord only.
In a three neuron reflex arc the afferent neurons synapse with?
In a three neuron reflex arc, the afferent neurons synapse with interneurons in the spinal cord or brainstem. The interneurons then synapse with efferent neurons which transmit the signal to the effector organ to initiate a response.
What causes a gag reflex in people?
The gag reflex is the body's natural defense mechanism to prevent choking by triggering a contraction in the back of the throat. It can be triggered by various factors such as foreign objects touching the back of the mouth, strong flavors or smells, or even emotional responses like anxiety or stress. Some people may also have a sensitive gag reflex, making them more prone to triggering it.
What are the type of nerve cells?
There are three different types of neurone: sensory, relay and motor - which are involved in a reflex arc.
What neurons are involved in a reflex?
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.
Swallowing a reflex action?
Yes, swallowing is a reflex action of which there are three phases. These are the oral phase, the pharyngeal phase and the esophageal phase.
What are the advantages of the fact that most reflex actions are governed by spinal cord?
Reflex actions are governed by three neurons only. If some body tries to hit on your eye, you blink by reflex action. Here again only three neurons are involved, although the middle neuron passes through your brain. Reflex action means only three neurons are involved and that saves lot of time required to think over the serious matter. So in reflex action you respond first and then brain notice the problem.The spinal reflex is fast. The reason it is fast is because the decisions are made at spinal cord level, rather than the nerves having to travel up to the brain and back down to the source.Because you are able to react quicker without having to think about it.1 It reduces the work load of brain. 2 The reflex action is under control of spinal cord, the message is sent to the brain later on.If it would have been under control of brain, it would have reqired longer duration for us to react, which has potential to cause damage to body tissue. Hence presence of spinal cord increases efficiency of reflex action.
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 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 three mechanisms cause a person to sneeze?
Ciliary Action, Peristaltic Motion, and Cough Reflex
Three forces involved in the upward movement of water in the plant?
cohesion,adhesion,capillary action
What is the sequence of events in a typical reflex arc?

How does the human reflex system work?
Reflex actions involve just three types of neurone. These are : - sensory neurones, - motor neurones, and Relay neurones which simply connect a sensory neurone and a motor neurone. We find relay neurones in the CNS, often in spinal cord
Does the nervous system control your blinking and sneezing?
The medulla oblongata is responsible for regulating several basic functions of the autonomic nervous system, including respiration, cardiac function, vasodilation, and reflexes like vomiting, coughing, sneezing, and swallowing.
How many major classes of neurons are there?
There are three major classes of neurons: sensory neurons, which receive information from the external environment; interneurons, which process and integrate this information; and motor neurons, which send signals to muscles and glands to produce a response.
