मानव शरीर-कान के बारे में सारी जानकारी

Manish Sharma

कानों से हम आवाज या ध्वनि तो सुनते ही हैं, लेकिन ये हमारे शरीर का संतुलन बनाए रखने में भी हमारी मदद करते हैं। बनावट के आधार पर कान को तीन भागों में बांटा जा सकता है- बाह्य कान (Outer ear), मध्य कान (Middle ear) और आंतरिक कान (Inner ear)।

जब किसी वस्तु से आवाज उत्पन्न होती है, तो ध्वनि तरंगें पैदा होती है, ये तरंगें बाह्य कान से होती हुई एक नली द्वारा कान के अंदर पहुंचती हैं। मध्य कान का कर्ण पटल (Eardrum) या टिम्पैनिक झिल्ली (Tympanic membrane) इन तरंगों के टकराने से कंपन (Vibrate) करने लगती हैं। कर्णपटल के ठीक पीछे तीन छोटी-छोटी अस्थिकाएं (Ossicles) होती हैं। इन्हें मैलियस या हैमर (The malleus or hammer) इन्कस या एनविल (The incus or anvil) तथा स्टैप्स या स्टिरप (The stapes or stirrup) कहते हैं। ये हड्डियाँ इन कपनों को कॉक्लिया (Cochlea) तक पहुंचा देती हैं। कॉक्लिया में एक द्रव पदार्थ (Fluid) भरा होता है, जिसके अंदर तंत्रिकाओं के सिरे (Nerve endings) होते हैं। कॉक्लिया में कपन होने से यह द्रव पदार्थ भी कपन करने लगता है। इन कंपनों से नाड़ियों के सिरे उत्तेजित हो उठते हैं और उत्तेजना से पैदा हुए संवेग श्रवण तंत्रिका (Auditory nerve) द्वारा मस्तिष्क में पहुंच जाते हैं। मस्तिष्क आवाज का विश्लेषण करता है और हमें आवाज सुनाई दे जाती है। हमारे कान तेज और मंद, सभी ध्वनियां सुन सकने में सक्षम होते हैं। कानों को निरोग रखने के लिए समय-समय पर उनकी सफाई करवानी जरूरी है।

  2. Er zijn tegenwoordig genoeg spelers die maandelijks quitte weten te spelen, en door een goede rakeback deal een prima inkomen hebben. Er zijn dus poker rooms die dit soort bonussystemen aanbieden. In dat soort gevallen wordt de rake rechtstreeks op je account gestort aan het einde van de maand of soms aan het einde van de week. Over het algemeen zijn er twee soorten online pokersites: die welke verbonden zijn aan een casino en die welke fungeren als onafhankelijke pokerplatforms. Bij beide types vinden we cashgames en toernooien die variëren in buy-ins en inzetlimieten van site tot site. Het komt hierop neer: bij de beste merken voor high roller pokerspelers kunt u deelnemen aan games en toernooien met veel hogere inzetten – zodat u kunt spelen hoe u wilt, zonder beperkingen.

    You can win money in a casino if the RTP is quite high. At BOSS Casino all the wins are possible, it’s just a matter of your luck. If you are lucky enough, you may get money right in the first session of your gambling. But make sure you understand that the casino doesn’t guarantee any wins – you need to build a good strategy to get a higher chance of winning. For getting the money, just keep your eye on slots, play demo slots, make small stakes and investigate how the slots act once they give you a win. Hunt for big wins with bigger stakes and make sure that internet gambling can be not only relaxing but also profitable for a player.

  6. Howdy would you mind sharing which blog platform you’re working with? I’m going to start my own blog in the near future but I’m having a difficult time choosing between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design seems different then most blogs and I’m looking for something completely unique. P.S Apologies for getting off-topic but I had to ask!

  7. Vegas Mobile casino is operated by ProgressPlay Limited. While the casino was launched in 2015, the Malta-based company that operates it was founded in 2012 and was licensed by the MGA in 2013. Building on its proprietary white label, it has developed numerous other online gambling platforms such as O’Reels, and Mr Vegas, to name a few. The casino has been around for over two decades now.

  8. Оттам насетне обаче Silentbet няма да ви занимава с никакви допълнителни формалности, които да усложнят процеса. Не се изисква от вас да правите нов акаунт или някакъв тип регистрация за сайта. Единствено трябва да намерите секцията с демо игрите, да подберете тази, която в най-голяма степен ви импонира и след това да започнете своето безплатно демо пътешествието в света на казиното. Когато играем в безплатен режим, можем да го правим колкото време пожелаем, без да загубим нито стотинка от парите си. Всяко завъртане при ротативките, например, се играе с виртуални кредити, което означава, че няма печалба, но няма и загуба. Така, ако сте истински фенове на слотовете или игрите на маса, можете да им се насладите в пълната им форма, макар и без участието на реални средства.

    Furthermore, with an increasing number of betting sites becoming far more involved in the esports industry, sponsoring teams and even whole tournaments, many sites, when they do this, will also offer specific promotions and bonuses on events that they have sponsored to their customers. A good example of this is Betway, who sponsored the BLAST Premier tournament and who offered a range of promotions on the event, including Odds Boost bets and extra betting markets. I hope that soon I will be able to update this researched guide to legal betting sites with information about formal Indian laws that address online betting sites. Until then, be sure to bet only on the trusted betting sites mentioned on My Betting Sites India.” Therefore, stay alert when it comes to the online betting world and ensure you are tightly secured from everywhere.

    Dunder Casino is establishing itself at the forefront of the influx of modern online casinos which are shaking up the older online betting sites. With its luxuriously fluid design Dunder Casino is a treat for the eyes and, with more than 600 games on offer, it is certainly a treat for serious real money players as well. The extremely generous bonus offer of up to $600 plus plenty of free spins will continue to attract new players to this cutting-edge online casino and the future is certainly looking bright for Dunder. Being a newly launched casino Dunder still has a bit of work to do, namely to organize more banking and support options and to get its promotion and VIP program launched. Still, the foundations of a strong casino is in place including a stellar slots selection and a tempting 200 free spins promotion for new players. You certainly won’t be a ‘Dunderhead’ for giving this site a try.
