It helps organisms to quickly adapt to an adverse circumstance that could have the potential to cause bodily harm or even death.

Reflex action is a rapid, automatic response to a stimulus which is not under the voluntary control of the brain, i.e. it is an involuntary action.

Conditioned or acquired: are acquired after learning or training eg. Reflex salivation. Unconditioned or Inborn: present since birth eg. Salivation when an object is placed in mouth.

In this reflex, neuron I has its peripheral ending within the tendons of the quadriceps muscle . Once the tendon is excessively or suddenly stretched, neuron I detects that and informs neuron II that action is needed to avoid any injury to the tendon. A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.

Reflex action is a sudden, unconcious and involuntary response of the effectors to a stimulus. Eg :- We suddenly withdraw our hand if we suddenly touch a hot object. In this reflex action, the nerves in the skin (receptor) detects the heat and passes the message through the sensory nerves to the spinal cord. Reflex action is generally controlled by spinal cord.
