Question

Filo · Accepted Answer

Difference between nervous and hormonal mechanisms:

Nervous system	Hormonal system
1. It consists of central nervous system (CNS) and peripheral nervous system (PNS).	1. It consists of endocrine glands.
2. A neuron is the structural and functional unit of the nervous system. It consists of dendrites, axon and soma. Dendrites are the small extension of nerve cells that receives signals from sensory receptors or other neurons. The long extension of the cell body of the nerve cell is called as axon that serves to conduct the nerve impulse away from the cell body/soma.	2. The endocrine secretion of glands (hormones) is released directly into the blood to affect the target cells.
3. Nerve impulses are not specific in their actions.	3. Hormones exhibit specific effect by affecting only target cells that carry the specific receptors.
4. Neural responses are quick and short lived.	4. Hormonal effects are the slow but long term.
5. The flow of information is rapid.	5. The flow of information is slow.
