• Differentiate between central and peripheral nervous system.
• Rods contain a pigment called rhodopsin, when light falls on rhodopsin, it breaks for generating a nerve impulse.
• Important 10th class biology chapter 3 question answer for all students of Punjab  Textbook Board.
•  In the absence of light, the breakdown products are again converted into rhodopsin. Body Synthesize rhodopsin from vitamin A and that is why the deficiency of vitamin A causes poor night vision. This problem is called night blindness.

• In younger people, epilepsy may be due to genetic or developmental causes. In people over age 40 years, brain tumors are more likely to cause epilepsy. Head trauma and Central nervous system infections may cause epilepsy at any age.

•  Write functions of hormones secreted by adrenal glands and pancreas.
  
•  Write a note on Pituitary Gland. OR Describe Thyroid gland. 
• Important class 10 biology chapter 3 notes for all students of Punjab  Textbook Board.
• v- Response: On receiving the message from coordinators, the effector performs action. This action is called response. For example, pulling our hand away from something very hot and the movement of the flower of sunflower towards light are responses.
• Important class 10th biology chapter 3 important notes for all students of Punjab  Textbook Board.
•  Usually, nervous coordination produces immediate but short-living responses while chemical coordination produces slow but long-living responses.
• Important biology class 10 chapter 3 important topics for all students of Punjab  Textbook Board.
• Human Nervous System: We have understood the basic model of the working of nervous system. The nervous system in man and in other higher animals is composed of two major components i.e. central nervous system and peripheral nervous system.
• Important 10th class biology chapter 3 short questions pdf for all students of Punjab  Textbook Board.
•  Central nervous system comprises of coordinators i.e. brain and spinal cord while peripheral nervous system consists of nerves that arise from central nervous system and spread in different parts of body.
• Important class 10th biology chapter 3 short question answer for all students of Punjab  Textbook Board.
•  All these components are made of neurons. Now we will first examine the structure and types of neuron and then we will go to the divisions of nervous system.
• Important class 10th biology chapter 3 short notes for all students of Punjab  Textbook Board.
• Nerve cell or Neuron: Nerve cell or neuron is the unit of the nervous system. The human nervous system consists of billions of neurons plus supporting (neuroglial) cells. 
• Important class 10 biology chapter 3 short questions and answers for all students of Punjab  Textbook Board.
• Neurons are specialized cells that are able to conduct nerve impulses from receptors to coordinators and from coordinators to effectors.

•  In this way they communicate with each other and with other types of body cells. The nucleus and most of the cytoplasm of a neuron is located in its cell body. Different processes extend out from cell body. These are called dendrites and axons.
• Important class 10 biology chapter 3 short questions and answers pdf for all students of Punjab  Textbook Board.
•  Dendrites conduct impulses toward cell body and axons conduct impulses away from cell body.
• Important class 10th biology chapter 3 important topics for all students of Punjab  Textbook Board.
• Schwann cells are special neuroglial cells located at regular intervals along axons.
• Important class 10 biology chapter 3 important short questions for all students of Punjab  Textbook Board.
•  In some neurons, Schwann cells secrete a fatty layer called myelin sheath, over axons. Between the areas of myelin on an axon, there are non-myelinated points, called the nodes of Ranvier. 
• Important class 10 biology chapter 3 important questions with answers pdf for all students of Punjab  Textbook Board.
• Myelin sheath is an insulator so the membrane coated with this sheath does not conduct nerve impulse. In such impulses are called saltatory (‘jumping’) impulses. This increases the speed of nerve impulse.
