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.
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.
receptor detects a stimulus - change in the environmentsensory neurone sends signal to relay neuronemotor neurone sends signal to effectoreffector produces a response
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.
The gag reflex is a type of reaction that often occurs automatically in the body. It occurs in the throat due to itÊnot wanting to or not being able to swallow.
The three main types of neurons are sensory, motor, and interneurons.
There are three different types of neurone: sensory, relay and motor - which are involved in a reflex arc.

Yes, swallowing is a reflex action of which there are three phases. These are the oral phase, the pharyngeal phase and the esophageal phase.
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.
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.

Ciliary Action, Peristaltic Motion, and Cough Reflex

cohesion,adhesion,capillary action
It has three acute and three reflex angles.
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
