The nervous system of the body receives, processes, and reacts to the collected information by using electrical impulses.
Two types of cells are present in the nervous system – neurons and glial cells. Neurons are responsible for collecting and transmitting the received information by sending electrical impulses through the entire body. Glial cells surround the neurons and provide them required metabolic and mechanical support.
Three Categories of Neurons are Visible Based on their Functions-
The primary objective of these neurons is to transmit impulses from the sense-receiving organs of the body such as ears, skin, eyes, tongue, and nose.
These types of neurons are designed to carry impulses to different glands and muscles.
Interneurons pass the signals between different types of neurons.
The Nervous System is Regulated by two Parts –
Central Nervous System or CNS
Brain and spinal cord are the two parts of CNS. As per the transmitted information through the neurons, the brain develops command for the rest of the body. The spinal cord works as the connector between the brain and the other parts of the body.
Peripheral Nervous System or PNS
The PNS has two parts – the somatic nervous system or SNS and the automatic nervous system or ANS. The SNS controls reflexes like pulling hands from a hot surface and other voluntary activities like movements of muscles.
The ANS regulates the sympathetic and parasympathetic nervous system. Also, this system controls activities that are not under conscious control.
The endocrine system controls the operations of organs and cells by using chemical signals. This chemical signals pass through the blood and is called hormones.
To know more differences between the nervous system and endocrine system, go through the study material available at our website. You will find all other chapters of Biology in great details, compiled by the best faculty. For faster access, the Vedantu app is also available.
1. Write any two Differences Between Endocrine and Nervous System.
Ans. The primary difference between nervous system and endocrine system is in nervous system electrical impulses are used, whereas the endocrine system involves chemical signal called hormones. Secondly, the nervous system is formed by a collection of neuron cells, glands and organs operate the endocrine system.
2. How does Endocrine Regulation System Work?
Ans. A mechanism called negative feedback controls this system. Controlling the concentration of the hormones is majorly regulated in this system.
3. What are the Parts of the Nervous System?
Ans. Central nervous system and peripheral nervous system are the two parts of the nervous system.
