Karnataka SSLC Class 10 Science Important Questions Chapter 7 Control and Coordination<\/h2>\n

Question 1.
\nWhat is meant by control and coordination system in organisms?
\nAnswer:
\nAll organisms respond to stimuli by sensing the changes in their environment. There must be coordination between the various organs of the body to respond suitably to those changes.<\/p>\n

Further, there must be a system to control the organs that sense and respond to the changes. The system that performs the control and coordination of the activities of the body is called control and co-ordination system.<\/p>\n

Question 2.
\nWhat is meant by coordination?
\nAnswer:
\nThe working together of various organs of the body of an organism in an appropriate manner to produce proper reaction to a stimulus is called coordination.<\/p>\n

Question 3.
\nWhat is the need for a system of control and coordination in an organism?
\nAnswer:
\nThe maintenance of the body functions in response to changes in the body by working together of various integrated body systems is known as coordination. All the movements that occur in response to stimuli may involve several organs whose activities are to be carefully coordinated and controlled.<\/p>\n

This is not only essential for our survival but also for efficient functioning. In the absence of this system of control and coordination, our body will not be able to function properly. For example, when we accidentally touch a hot utensil, we immediately withdraw our hand. In the absence of nerve transmission, we may get burns.<\/p>\n

Question 4.
\nMention the two ways in which coordination between the organs is brought about in higher order animals.
\nAnswer:
\nCo-ordination between the organs in higher order animals is brought about in two ways namely by the nervous system and the endocrine system.<\/p>\n

Question 5.
\nWhat is the structural and functional unit of our nervous system called?
\nAnswer:
\nThe basic unit of our nervous system is a set of specialized cells called neurons.<\/p>\n

Question 6.
\nExplain briefly how we perceive a sensation.
\nAnswer:
\nA sense organ in our body receives the stimuli from the environment. Each stimulus is passed to the brain through the sensory nerves. The stimulus is interpreted by the relevant part of the brain. When this happens, we perceive the stimulus.<\/p>\n

Question 7.
\nWhy are sense organs called \u2018receptors \u2019 in the control and coordination system of an organism?
\nAnswer:
\nAll our sense organs such as eye, ear, nose, tongue and skin receive stimuli from the environment and pass it on to the central nervous system through the sensory nerves. This is why sense organs are called \u2018receptors\u2019 in the control and coordination system.<\/p>\n

Question 8.
\nWhat is the function of receptors in our body? Think of situations where receptors do not work properly. What problems are likely to arise?
\nAnswer:
\nReceptors are present in all parts of our body for example in skin, eye, nose, tongue etc. They detect the signals and send them through sensory nerves to the brain in the form of electrical signals. If these receptors are damaged, then they will not detect the input and the body will not be able to respond to the situation. This may harm our body in a danger situation.<\/p>\n

Question 9.
\nWhat is a neuron?
\nAnswer:
\nThe structural and functional unit of our nervous system is called a neuron. It is another name for a nerve cell.<\/p>\n

Question 10.
\nDraw the structure of a neuron and explain its function.
