There are different chapters designed by the experts as a part of the NCERT syllabus. It helps the learner to get good command on the subject. The course is designed in a manner that can offer great insight to the subject and also presented in a manner that can help the learner command the subject in a short span.
For Biology in your class 10 board exam, you might refer to the NCERT Solutions. The Control and Coordination Class 10 NCERT Solutions which is the chapter 7 in the book gives you an idea about the structure and the solved questions that you must follow. The following article briefs on the points covered and touched upon in the chapter mentioned above and fall under the syllabus of CBSE Class 10 Science Life Processes.
Coordination is the process by which various body parts are perfectly working in harmony in reaction to stimuli.
1) Animal coordination is performed by the nervous and endocrine system. The brain, spinal cord, and nerves comprise nervous system. The responsibility of coordination is handled by the receptors which are the organs which receive the stimuli and instantly convey it through nerves to the brain and spinal cord. There are different types of receptors; they are photoreceptors, photoreceptors, olfactory receptors, gustatory receptors and tango receptors. Effectors are the muscles and glands which react to the messages that are sent from the brain and spinal cord to the different parts of the body. Sensory nerves which carry messages from the receptors to the brain and the spinal cord and motor nerves which help in the transmission of a message from the brain and spinal cord to the effectors.
2) The nervous system, an important system, in humans consists of the peripheral and central nervous system. CNS consists of the brain and spinal cord, PNS consists of cranial nerves and spinal nerves.
3) Neuron or nerve cell is the most important part of this whole process of coordination in human beings. The chapter also deals with the composition, diagram, and function of the neurons and the nerve cells.
4) The brain is the most supreme coordinating center of the whole body network. It consists of the forebrain, hindbrain, cerebellum, and pons.
5) The spinal cord carries the message to and fro the brain and controls reflexes.
Ways in which body reacts to stimuli:
- a) Reflex action- Sudden involuntary and unconscious reaction to stimuli, example- withdrawing hand when touching a hot object.
- b) Reflex arc- it is the pathway of reflexes. Receptors receive impulses, and it passes through sensory nerves.
Coordination In Plants
In plants, it is performed by plant hormones and phytohormones. There are five types of plant hormones they are auxins, gibberellins, cytokinins, abscisic acid, and ethylene. They have two types of movement tropic and nastic.
Hormones in humans
Endocrine glands in humans also help in control and coordination. The endocrine glands in our body are pineal, hypothalamus, pituitary, thyroid, parathyroid, thymus, adrenal, pancreas, testes and ovary.
Thus these are the topics which are referred to in the CBSE Class 10 Science Control and Coordination chapter.
