 नवर सिस्टम का और सैंसरी सिस्टम्स का हम जगर कर रहें, उसकी समरी ब्यान कर रहें, कुई हम देल में तो आलडी पच्छुके, लेगर इस पार्ट 3 में ज़ा थोडी सी और जस तो रिकोल यूँ, के हम क्या कुछ पच्छुके, क्या इजामपल्स

nerve impulse is translated into a recognizable sensation जेसे हम जेसे हम sound wave कैसकते हैं या light wave भी कैसकते हैं अब inverटी ब्रेट की अंदर sensory receptors ये barometers हैं और in barometers की अंदर वास तोर पे हम ने जेगर किया था स्तेटो सिस्ट का तो these are the organs जो के pressure बेरो मीटर जासी होते हैं यो air pressure वगा दिटमन करते हैं या उसे हम मालुम करते हैं तो इसकी अंदर स्तेटो सिस्ट से हैं जिसकी अंदर बख्यादा कंक्रीशन्स होते हैं तो वो से वो अगर water living animals हैं तो वो फिर वो से पड़ा चलता है कितने pressure में हैं तो the chemoreceptors they are quite self-explanatory they are sensitive to the chemicals chemicals, poisons भी होगते हैं non-poisons भी होगते हैं और पानी की अंदर बहुत सारे तो ये animals हैं जो के अगर ये sensitive नहीं होंगे तो they cannot protect themselves they cannot hide themselves they cannot move that from that particular place then there is the georeceptors gravity is related तो इसकी अंदर भी statusis हैं और these are that respond to gravity that respond to gravity then there is the hydro hygroreceptors which are sensitive to the air contents like water air contents because the air can be dry it can be wet it can be wet then all those things they are sensitive to it then the phonoreceptors like the tympanic organs like the ears like the tympanic membrane the ear drum which vibrates and then the sensations and vibrations they go towards the brain then there are photoreceptors which are sensitive to light or in invertebrates stigmata like in uglina oscilli compound eyes complex camera eyes that respond to light in this we have understood the details then the photoreceptors they respond to mechanical induced changes caused by stretching and in the body or in the knees or in any body where there is stretching then there are these proprioceptors there are also nerve endings from which it is known whether this part of it is how far it has been stretched then the tactile receptors such as bristles sensilla then spines city, tubercles sens touch so these are the organs which are found in invertebrates in different groups of animals which are sensitive to touch then vertebrate sensory receptors which have a lateral line system which is found in fishes and some amphibians and platypus now platypus this is duckbill platypus for example there is a mammal which has a lateral line so they are sensitive to water disturbance when there is a little water or turbulence then this is very sensitive and then they leave that place when there is a lot of agitating type of water now lateral line systems are in jawless fishes then jawed fishes and certain amphibians they contain ampullary organs which are sensitive to electric currents in water and production of generator potential so these lateral line systems have been mentioned in detail then the hearing and equilibrium in air and water hearing which is an audition and equilibrium these two things are present in one organ and they are considered together both sensations are received in the same vertebrate organ which is called as the ear now skin receptors which are sensitive to heat and cold then when there are pit organs in snakes these pit organs they are usually in the head region so they are sensitive to this is heat that is high temperature so mechanical receptors they are bare sensory nerve endings bare means they are not covered by these are exposed nerve endings these are touched with the certain stimulus so there is a sensation and even in human skin there are different types of mechanical stimuli to bear or to feel these are bachayda capsules or capsules so bare sensory nerve endings then the messenger's capsule then bulb of cross juice cross juice you can pronounce it in different ways you can also call it cross then in the peccinian capsule then the vibrici these are the hair like structures which are usually in the cats or lions or tigers here which are near the nose then the vian vian bdini also can be seen in the animals we have studied in detail then photoreceptor cells which are rods and cones they are very specialized cells or in which we have mentioned monocular or binocular vian then accommodation is a very complex organ and at a time a lot of things are happening in this these rods and cones they are also working then the redopsin is being formed replenish break is also being done and binocular vian then we see from both our eyes in some animals there is monocular vian then all this we have gone through it then there is a sonar eco-location which is usually in bats then whales and dolphins cave-dwelling birds this sonar is very much like radar system so waves come out and these are the animals they feel them they feel them when they rebound then this smell which is receptors in nasal cavity then Jacobson's organ which is also in reptiles which is Jacobson's organ apart from the other organs then the taste birds on tongue then barbules in fishes or birds pharynx these taste birds there are very few taste birds on the skin sorry on the tongue of the birds but in pharynx in pharynx these taste receptors in birds so this is all about this is the summary this was the summary in three parts it is not the explanation we have gone through it just to recall that we have read in this chapter and this will definitely help you to understand this complete chapter so this is all about this part three of the summary of the chapter
