Question

Explain the difference between Nervous system and Endocrine system of man

Answer 1

The main body function system is the nervous system. The nervous system consists of various nerve cells that are located in the brain. The endocrine system is made up of glands that produce chemicals in response to stimuli.

Complete Answer:

S.no	Nervous system	Endocrine System
1	The nervous system can be described as a huge system of nerves that transfer messages or signals to or from the brain and the spinal cord to many other parts of the body.	The endocrine system is a set of hormone-producing glands that act in the regulation of body growth and development, metabolism, tissue function, fertility, sleep, rage, emotions and other internal functions.
2	The nervous system is made up electrical impulses or pulses to transmit signals via the neuron	The endocrine system uses hormones that serve as a chemical messenger to transmit messages to the target cell via the bloodstream in the body.
3	The entire nervous system is made up of the brain and spinal cord.	The endocrine system consists of important glands and organs like thyroid, pituitary glands and reproductive organs namely ovaries and testes.
4	Neurons in the brain help to transmit the nerve impulses	Here, the blood vessels help to transmit the hormones
5	The nervous system demonstrates a fast reaction to stimuli, due to the action potentials and neurotransmitters.	The endocrine system reacts slowly by secreting the hormones, flowing across the circulatory system to just the target tissue.
6	Nerve impulses utilise the neurotransmitters in the neuronal clefts and the sodium and potassium channels until accessing the targeted cells.	Hormones reach the target cells by disseminating across the plasma membrane or just by attaching to the cell receptor.
7	The nervous system will be under active and involuntary control.	The endocrine system will be under only involuntary control.

Note: Both the systems undergo regulatory mechanisms that enable contact between tissues, organs and cells. These mechanisms are responsible for regulating and organising the signals sent to the body, internally or externally. This Control tends to preserve the homeostasis and other functions of the system.
