Answer 1

A true reflex arc involves only a few neurons, or cells of the nervous system, and the information goes only from your body to your spinal cord, not your brain. Let's look at the cells that make up the reflex arc and how they work.

COMPONENTS OF A REFLEX ARC 

1. The sensory receptor 
2. The afferent nerve 
3.  The Central nervous system integrator (usually the spinal cord grey matter, and often involving one or more interneurons) 
4. The efferent nerve 
5. The effector organ (eg. A muscle)

The complete pathways that followed in Reflex Action.

Name the components of reflex arc?

❶❫ Receptor or Sensory 0rgan:

It receives the stimulus & initiate a sensory impulse.

❷❫ Sensory or Afferent Nerve:

It carries the impulse from receptor organs to spinal cord.

❸❫ Spinal cord:

It changes sensory impulse into a motor impulse.

❹❫ Motor or Efferent Nerve:

It conduct the nerve impulse from spinal cord to the effector organs.

❺❫ Effector organ:

It gives the response producing movement of some muscles or secretion from a gland.
