NCERT Solutions for Class 10 Science Chapter 6 Control and Coordination

The main topics covered in this chapter are Introduction to Control and Coordination and the need for control and coordination in organisms. Overview of the nervous system and the endocrine system.

The brief summary of class 10 science chapter 6 is as follows:

• Introduction to Control and Coordination: The chapter 6 of 10th science, begins by discussing the concept of movement in living organisms, distinguishing between movements caused by growth (as in plants) and those not connected to growth (as in animals). It emphasizes the importance of movement as a response to environmental changes and the necessity for controlled movement in response to various stimuli.
• Nervous and Muscular Tissues in Animals: This chapter explains how control and coordination in animals are facilitated by nervous and muscular tissues. It describes the structure of neurons, the transmission of nerve impulses, and the role of synapses in this process.
• Sensory Reception and Response: 10th science chapter 6 delves into how sensory information is detected by receptors located in sense organs and how this information triggers electrical impulses in nerve cells, leading to appropriate responses.
• Reflex Actions: The concept of reflex actions is explored, highlighting how these are quick, involuntary responses to stimuli. The chapter 6 of 10th science discusses the reflex arc and its efficiency in providing rapid responses without the need for conscious thought.
• Human Brain and Spinal Cord: The role of the human brain and spinal cord in control and coordination is examined. The brain is described as the main coordinating center, integrating sensory information and facilitating voluntary actions. The spinal cord’s role in reflex actions and as a conduit for information to and from the brain is also discussed.
• Functions of Different Brain Regions: Chapter 6, of class 10 science, breaks down the functions of various parts of the brain, including the fore-brain, mid-brain, and hind-brain. It details how different brain regions are responsible for processing sensory information, voluntary actions, and involuntary actions like blood pressure regulation and digestion.
• Role of the Cerebellum: The cerebellum’s function in maintaining posture, balance, and precision in voluntary actions is highlighted.
• Class 10 Science chapter 6 provides an overview of the key concepts related to control and coordination in living organisms, particularly focusing on the nervous system and brain functions in humans.

The topics covered under the nervous system are the Structure and function of neurons (nerve cells). Generation and transmission of nerve impulses. Parts of the human nervous system (central nervous system and peripheral nervous system). Role of the central nervous system (brain and spinal cord). Reflex actions and their significance.

How sensory organs detect external stimuli (light, sound, chemicals, etc.). Role of sense organs in gathering information about the environment. The senses that we tend to think of as exclusive to animals, which also exist in plants: they see, hear, smell, and taste, and of course respond to touch.

The brain is the most complex part of the human body. The human brain performs activities like intelligence, interpreter of the senses, initiator of body movement, and controller of behavior. Structure and functions of different parts of the brain (forebrain, midbrain, and hindbrain). Control of various body functions by different regions of the brain. The importance of the brain in regulating activities like thinking, memory, and emotions.

The endocrine system and its components (endocrine glands). Role of hormones in the body. Key endocrine glands such as the pituitary gland, thyroid gland, adrenal gland, pancreas, and gonads. Functions of hormones produced by these glands. Hormones in Animals, Hormones involved in growth, metabolism, and reproduction. Role of hormones like insulin and glucagon in blood sugar regulation. Control of growth hormones and sex hormones.

Class 10 Science chapter 6 helps students understand how living organisms, including humans and plants, control and coordinate various physiological processes to adapt to their surroundings and maintain internal balance. It provides a fundamental understanding of the nervous and endocrine systems and their roles in regulating bodily functions.

Question:
State the function of any three of the structural and functional unit of nervous system.
Answer:
Nervous system: Main parts of nervous system are: (i) Central nervous system, (ii) Peripheral nervous system, (iii) Autonomous System.
(i) Central Nervous System: It consist of
(a) Brain receives information carrying impulses from all the sensory organs (by sensory nerves) of the body and also from the spinal cord. The brain respond to the information by sending its own instructions (through motor nerves) to the muscles and glands to act accordingly. The brain also stores information and act as organ of thought and intelligence.

(b) Spinal cord: It is concerned with spinal reflex actions and the conduction of nerve impulses to and from the brain.
(ii) Peripheral Nervous system: it is composed of cranial nerves (nerves from the brain) and the spinal nerves. Both of these consist of sensory and motor neurons. So, they carry sensations to and messages from the brain and the spinal cord.
(iii) Autonomous Nervous System: It is that part of the peripheral nervous system which controls the activities of the internal organs such as stomach, heart-beat, etc. automatically even without our thinking about them. Its nerves are attached to the smooth muscles and control the activities of internal organs of the body involuntarily, many these nerves are connected with the mid- brain and hind-brain.

To help students prepare for exams, the platform may offer sample papers and previous years’ question papers. Solving these papers can help students familiarize themselves with the exam pattern and practice answering questions effectively. Many online education platforms, like Tiwari Academy, have doubt-clearing sessions where students can ask questions related to the chapter, and educators or experts will provide explanations and clarifications.

Question 1:
(a) If the cerebellum is not functioning properly, state the activities of our body that are affected.
(b) how do muscles move?

Answer 1:
(a) Cerebellum is not functioning properly may affect-
(i)Walking in straight line
(ii)Riding a cycle
(iii)Maintaining the posture and balance of the body
(iv)Movement is very coordinate, the patient sways in walking and tend to fall towards the affected side.
(v)It is responsible for precision of voluntary actions.
(b) When the decision to move is conveyed by a nerve to a muscle, it has to act. In response to nervous electrical impulses. The special proteins of the muscle change both their shape and their arrangement in the cell. This new arrangement of these proteins give the muscle cells a shorter form that causes movement of the muscle.

Interactive quizzes and tests can help students assess their knowledge and track their progress. These quizzes may be designed to simulate the format of actual exams. Class 10 Science Chapter 6 involve complex diagrams and illustrations related to the nervous system, sense organs, and hormone regulation. Tiwari Academy provide labeled diagrams and explanations to help students understand these concepts better.

Question:
“Use of iodised salt is essential”. List three reasons to justify this statement.
Answer:
(i) Iodised salt supplies sufficient amount of iodine through our diet, even in the areas where iodine is not available naturally through water or otherwise in diet.
(ii) Iodine is necessary for the thyroid glands to make thyroxine hormone.
(iii) Proper supply of iodine maintains thyroxine level that regulates carbohydrate, protein, and fat metabolism to provide the best balance for growth.
(iv) Deficiency of iodine causes many diseases such as Goitre.

Diagrams related to the nervous system, sense organs, and hormone regulation are often included in the examination. Students may be asked to label these diagrams or explain specific parts and their functions. Reflex actions, a key topic in chapter 6 of 10th Science, are frequently examined. Questions may require students to explain the sequence of events in a reflex arc or discuss the significance of reflexes in protecting the body.

The chapter 6 of 10th Science covers the endocrine system and hormones. Students may be asked to identify hormones, their sources, and their functions. Additionally, questions related to the regulation of bodily functions by hormones are common. Some questions may require students to compare and contrast the roles of the nervous system and the endocrine system in control and coordination.

Understanding these differences is crucial for answering such questions accurately. To assess a student’s application of knowledge, examination questions may present scenarios or case studies related to control and coordination. Students may need to analyze these situations and explain how the body responds.

Class 10 Science chapter 6 bridges the gap between biology and physiology. Students may encounter interdisciplinary questions that require them to integrate knowledge of control and coordination with related concepts in physics or chemistry. A strong understanding of control and coordination is essential for students who plan to pursue biology or related fields in the future. This chapter serves as a foundation for more advanced studies.
