NCERT Notes Class 10 Control and Coordination

NCERT Class 10 Science Notes Chapter 6: Control and Coordination in the living organism mean the ability to control and coordinate different body functions to complement each other. Separately control means the ability of our body to have power of regulation over any mechanism whereas coordination means the process by which all the different parts of the body work together to produce the desired outcome. You will find the NCERT Control and Coordination Notes for Chapter 6 Class 10 Notes here.

Control and Coordination in Animals

In lower animals i.e. every phylum of invertebrates (except Sponges) control and coordination are achieved with the help of the basic form of the nervous system. In sponges, the coordination is dependent on their cilium generating the signals to respond to any stimuli as they lack a nervous system. Whereas in vertebrates there is well-developed nervous system and endocrine system that oversees the whole process of control and coordination....

Nervous System

The nervous system of all animals is made up of specialized cells called nerve cells or neurons. These specialized cells are responsible for responding to stimuli and then coordinating the body’s actions. This is why nerve cells are called the “structural and functional unit” of the nervous system....

The Central Nervous System

The main processing unit of all information is the CNS which consists of the brain and the spinal cord....

Peripheral Nervous System

The network of nerves that arise from the brain and spinal cord spreads throughout the body conducting impulses between the CNS and the body. It comprises two main types of nerves:...

Autonomic Nervous System

Autonomous means “self-governing”, so these nervous systems as considered self-governing nervous systems. It controls those functions which we cannot control as per our will i.e. involuntary actions like activities of internal organs e.g. movement of food through the stomach, flow of blood, etc. As it controls the function of internal or visceral organs of the body, it is also called the visceral nervous system. It can be categorized into two categories;...

Reflex Actions and Reflex Arc

Any sudden, immediate, involuntary, and mechanical response to a stimulus that is done without the will of the body is called reflex action. Mostly these reactions are controlled by the spinal cord and thus called spinal reflex action; however, some reflex actions are also controlled by the brain and are called cerebral reflex action....

Endocrine Gland

Ductless glands secrete their secretion (hormones) directly into the blood. Examples are; the pituitary gland, thyroid glands, etc....

Control and Coordination in Plants

Plants lack complex control and coordination like animals as they don’t have a nervous system or glandular system but they need internal coordination to maintain growth and development. They have only chemical coordination with the help of plant hormones or phytohormones which makes them either dependent on external stimuli like light, gravitational force, etc., or growth-dependent movements like the directional movement of stem upwards and root downwards. The plant mainly shows two types of movement; nastic and tropic movements....
