A NEURON (NERVE CELL) Function of the Nervous System

 All the functions  of the nervous system outlined above are carried out because of three basic features of this system:

(i) Sensory - The Receptors detect internal as well as external  stimuli, e.g., temperature receptors located in the hand detect a hot object.
(ii) Integrative -Inter-neurons integrate or process the information that is received and make an appropriate decision for final response, e.g., Inter-neurons decide that the hand should be moved away from the hot object to prevent burning.

Motor= Effectors respond to integration decisions, e.g., withdrawal of hand from the hot object.
