Question

Compare and contrast nervous and hormonal mechanisms for control and coordination in animals.

Answer 1

Hint: The nervous system receives the knowledge, processes it, and triggers reactions. The neurons help in transmitting signals. On the contrary, hormones diffuse through the cell wall of the target cells and bind a receptor protein within the cytoplasm of the cell.

Complete step by step answer:

Nervous system	Hormonal System
- It consists of the central nervous system (CNS) and peripheral nervous system (PNS).	- It consists of endocrine glands.
- A neuron is a structural and functional unit of the nervous system. It consists of dendrites, axon and soma. Dendrites are a kind of tiny extension of nerve cells that receives signals from sensory receptors or other neurons. The long extension of the cell body of the neuron is named as axon that serves to conduct the impulse far from the cell body/soma.	- The endocrine secretion of glands (hormones) releases directly into the blood to affect the target cells.
- Nerve impulses are inaccurate in their actions.	- Hormones exhibit specific effects by affecting only target cells that carry the specific receptors.
- Neural responses are quick and short-lived.	- Hormonal effects are slow but are long term.
- The flow of information is rapid.	- The flow of information is very slow.

Note:
Nervous System: Consists of Brain, Spinal network and an enormous network of nerves.
Functions
- To receive the data from the environment through the sensory receptor.
- Transportation of data to the brain through the spinal cord and nerves.
- After analyzing the data, to act accordingly through muscles and glands.
Endocrine system may be a system of endocrine glands in our body which secretes a chemical substance called hormones to different parts of the body. This technique controls various activities of the body.
- Hormones: These are the chemical substances secreted by endocrine glands known as hormones. Hormones are like messengers that are liable for telling some a part of the body to try and do something or to prevent doing something.
- Glands are specialized groups of cells or organs that secrete different chemical substances. These are Endocrine glands and Exocrine glands
