The purpose is to prevent injury. For example, if someone shines a bright light in your eyes, your pupils automatically get smaller so that less light gets into the eye- this stops it getting damaged. Or if you get a shock, your body releases the hormone called ADRENALINE automastically- it dos'nt wait for a response.

Many things in life must occur automatically. If we had to think about every breath before we took it, or think about how hot a stove is before we remove our hand, we would have a very low survival probability. People who think about what to do when something jumps out of the bushes at them will probably not have many children. Neither would people who had to think about blinking when a bee flew toward their eye.
These problems are all addressed by reflexes. They are "hardwired" responses that get us out of the immediate danger (hopefully) in much less time than we would be able to manage if we had to reason out every response.
Reflexes are the reaction which you give to a stimulus without the impulse reaching the brain.These impulses are prosesses by the spinal cord.This will help to save ourselves in the situations where the brain is subjected to shock and is not in a working condition.
If you didn't pull your hand away when putting it into flames, you would get burned.
Hormones have nothing to do in reflex arc.

The nervous system's main function is to communicate with and control every part of the body, whether it be voluntary or involuntary. It controls every reflex, action, emotion, and thought.
Somatic reflex
Hormones have nothing to do in reflex arc.
Spinal Reflex
Anatomically no. Reflexes are involuntary responses to a stimulus.

"Learned behaviors" are simply behaviors that you must learn instead of behaviors that happen automatically.Instinct and reflex are examples of behaviors which do not have to be learned - birds instinctively know how to build nests, you blink your eyes by reflex (most of the time), and hitting your knee with a little hammer makes your leg jerk.Anything that you have to practice in order to learn it is a learned behavior - walking, talking, playing sports, school work, etc.
Behaviors triggered by a reflex. Examples of this include sneezing after inhaling dust or the knee-jerk reaction when a doctor hammers your knee.
The instrument used by a doctor to test knee reflex is a reflex hammer. The doctor will tap the patellar tendon just below the kneecap with the reflex hammer to elicit a reflex response, which helps assess the function of the nerves and spinal cord.

Controls reflex of turning eyes and head towards a visual stimulus.
