Human Nervous System
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.
