Firstly your receptor cells pick up a stimuli and sends an electrical impulse along the sensory neurone's axon to the spinal cord.the impulse is then passed onto the relay neurons IN the CNS(the spinal cord decides what to do but the brain is also informed).
The relay neurone then passes the command from the spinal cord in the form if an impulse to the motor neurone.the impulse travels along its axon to the effector.
Hope it helps
P.S. •relay neurones exist only within the CNS and not outside it.
•reflex arcs take the shortest possible route

Why are nervous system reflex action important?
nervous system controll and co ordinate the body functioning. reflex action helps to safeguarde the body from all sorts of sudden unexpected dangers
Which is the control centre of a reflex action?
The nervous system.
What organ of the nervous system is bypassed in a reflex action?
spinal cord
When you get pin pricked you immediately remove your hand why?
because of reflex action by our nervous system
What kind of action is a sneeze?
It is a reflex action which is an autonomic (automatic) nervous system reaction to stimuli. It is the respiratory system and the nervous system working together. The pepper is an irritant to the nasal mucosa and it signals to the brain to sneeze and get it out of there. Another example of a reflex action is when you touch something extremely hot....you quickly pull your hand away.
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.
Why is the patellar reflex called a somatic reflex?
The Patellar reflex is an example of a somatic reflex. This refers to the branch of the nervous system that the reflex pertains to. The somatic branch is part of the Peripheral Nervous system, meaning that it's reflex arc does not pass through the central nervous system (the spinal cord and the brain)
When an action potential passes through the central nervous system without going to the brain it is called a?
I believe that you are referring to a "reflex".
The pupillary light reflex is control by what autonomic nervous system?
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
Is a sneeze a reflex action?
Yes, a sneeze is a reflex action controlled by the autonomic nervous system. It is the body's way of expelling irritants from the nasal passages to protect the respiratory system.
What does the central nervous system have to do with swallowing?
Swallowing involves the central nervous system and is a reflex.
What division of the autonomic nervous system mediates the reflex release of saliva?
The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients.
