Understanding the Nervous System and Reflex Actions 🧠 | Signs of Health | ISL News

Have you ever touched something hot and pulled your hand away instantly? Or remembered an old song after hearing just one line? These actions happen because of the nervous system, the body's control and communication system. It helps us think, feel, remember, move and react to the world around us. The nervous system has three main parts: the brain, spinal cord and nerves. They work together every second of the day. The brain is the body's control centre. It controls our thoughts, memory, emotions, movement, breathing and heartbeat, and keeps working even while we sleep. The spinal cord carries messages between the brain and the rest of the body. Sometimes the body reacts before we even think. This is called a reflex action, which helps protect us from injury. Nerves form a communication network throughout the body. They carry information about sight, sound, touch, taste and smell, and help control movement, breathing, digestion and heartbeat. The nervous system works with every other system in the body. It helps us move, speak, learn, remember and control our emotions. If the nervous system is affected, it can cause memory problems, poor balance, headaches and difficulty in movement. Stress, poor sleep, injuries and some diseases can affect it. To keep your nervous system healthy, get enough sleep, eat nutritious food, exercise regularly, reduce stress and keep your mind active. The nervous system works every moment of our lives and controls almost everything we do, so taking care of it is very important. #NervousSystem #HumanBody #ReflexAction #Brain #SpinalCord #Nerves #ScienceFacts #Biology #HumanAnatomy #ScienceInISL #ISHNews ISH News broadcasts the Daily News and Entertainment online in Deaf-friendly, accessible formats in Indian Sign Language (ISL), with visual images with titles, voice-over, and closed-captions.
