Question

Similarities and differences between nervous and hormonal mechanism for control and coordination in animals?

Answer 1

Animals:

1. Control and coordination in all animals, including humans, are carried out by neurons and a chemical called hormones.
2. A neuron is a type of nerve cell and is the fundamental unit of the neurological system.
3. The neuron is a specialized cell that communicates information throughout the body to carry out its purpose.
4. The specialized glands known as the endocrine glands produce hormones directly into the blood as chemical messengers.
5. Different hormones released by various glands act as messengers in various parts of the body.

Similarities in Animal Control and Coordination Mechanisms between Nervous and Hormonal Systems:

1. The hormonal and nervous systems both function as an organ's receptor and are affected.
2. The human brain's central nervous system regulates both the neurological and hormonal systems.
   

The nervous and hormonal mechanisms in animals:

1. The region of an animal's body that coordinates behavior and sends messages between various bodily parts is known as the nervous system.
   
2. Hormones are molecules that are produced into the blood by a number of endocrine glands and then carried to the appropriate organs, where they work by regulating a number of metabolic processes.

Differences between Nervous and Hormonal mechanism for Control and Coordination in Animals

Nervous system	Hormonal system
1. Transmits information through electrical impulses.	1.Transmits information through blood cells.
2. Signal transmission is fast	2. Signal transmission is slow
3. The effects are short-lived.	3. It has prolonged effects.
4. Affects only a particular part of the body.	4. Affect different organs of the body
5. No changes to metabolic processes	5. Effect metabolic processes
