How does nervous system differ from …

• The nervous system uses "electrical signals" to control and coordinate through the neurons, neurotransmitters and action potentials; whereas, the endocrine system uses chemical signals through the hormones as chemical messengers.
• The 'nervous system' acts in quick response to a stimulus but endocrine system acts slowly by secreting and transporting hormones to the target cells.
• The actions brought about by nervous system are localized, mostly temporary and also reversible. The actions are widespread and permanent.

The nervous system consists of special cells called neurons.  It can be divided into two main parts – central nervous system and peripheral nervous system. 

Neurons are specialized cells of the nervous system. They use electrical and chemical signals for transferring information.

Functions of nervous system:

1. The function of the nervous system is to coordinate the activities of our body.
2. It helps all other systems of our body to work together.
3. It receives information from the surroundings, processes it, interprets it and then responds accordingly. However, the endocrine glands do not have ducts to secrete their hormones. They release hormones directly into the blood of a person and reach the concerned body part through the blood and act on it.
