The human nervous system is responsible for controlling and coordinating all the activities of the human body.
The three major functions of the human nervous system are:
Gathering or assembling sensory information from the body and external environment.
Processing and interpreting the sensory information acquired.
Conveying or transferring appropriate response to the sensory information acquired.
The nervous system is mainly divided into two, namely:
The Central Nervous System (CNS) comprises the brain and spinal cord.
The brain is majorly involved in the perception and processing of sensory input. It also regulates or manages voluntary motor responses and homeostatic mechanisms.
The spinal cord act as a pathway for the transmission of information between the brain and the peripheral nervous system. It also takes action on reflex actions.
The Peripheral Nervous System (PNS) comprises sensory/motor neurons and ganglion.
