What is the function of our nervous system class 10?

Nervous System : Consists of Brain, Spinal network, and a huge network of nerves. The function of the Nervous system – To receive the information from the environment and various body parts (Stimuli Response) and act accordingly through muscles and glands.

What are the two main divisions of the nervous system Chapter 10?

The central and peripheral nervous systems are the two main divisions of the nervous system. The central nervous system includes the brain and spinal cord, whereas the peripheral nervous system consists mainly of nerves that connect the central nervous system with the rest of the body.

What is nervous system class 10?

Nervous system is the organ system present in the animals to control and coordinate different activities of the body. Nervous system comprises of the brain, the spinal cord, and a huge network of nerves that are spread throughout the body.

What is the main purpose of the nervous system?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

What are 3 functions of nervous system?

Divisions of the Nervous System Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

What are the main components of nervous system?

The nervous system has two main parts:

• The central nervous system is made up of the brain and spinal cord.
• The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What is nervous system Class 5?

The nervous system includes the brain, nerves and spinal cord. It is the communication center for the body, sending and receiving messages, regulating body functions and serving as the control center for the five senses and for emotions, speech, coordination, balance, and learning.

What are the 3 main functions of nervous system?

What is the function of the nervous system?

This leads to the specific response that will be generated. Figure 12.1.2 – Nervous System Function: Integration occurs in the CNS where sensory information from the periphery is processed and interpreted. The CNS then creates a motor plan that is executed by the efferent branch working with effector organs.

Why is the peripheral nervous system called the PNS?

The peripheral nervous system is so named because it is in the periphery—meaning beyond the brain and spinal cord. Figure 12.1.1 – Central and Peripheral Nervous System: The CNS contains the brain and spinal cord, the PNS includes nerves.

What are the anatomical divisions of the nervous system?

The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord. The PNS is everything else and includes afferent and efferent branches with further subdivisions for somatic, visceral and autonomic function.

How are voluntary responses governed by the nervous system?

Voluntary responses are governed by the somatic nervous system and involuntary responses are governed by the autonomic nervous system, which are discussed in the next section. Integration. Stimuli that are received by sensory structures are communicated to the nervous system where that information is processed.
