Nervous System




Central Nervous System → set of learning, intelligence & emotion

Basic Functions:

Take information from external & internal environment

Compares & contrasts the sensory information

Motor Response

Store of sensory information

Peripheral Nervous system → includes 12 pairs of cranial nerves & 31 pairs of spinal nerves
Basic Functions:

Takes information to CNS from peripheral system
