 अरब चोल, अब मब नवस चीश्टम्क भाद जिखर जोगा वो खया सेंसरी अगन्स का होगा और इसे हम सेंसरी इसआप्श्विन के खेडिंग में हम इसो पहले इंट्रडऊक्षन जिब करतें, इंट्रडऊक्षने इस खच्टर दे. Damn human can do. We are very familiar. If the five senses, which is which are all present, then in our Head region of this myself eight senses here which is the which extends over all the body. Though these are sites smell hearing tastes in touch or all commonly known, you can see the senses now apart from these apart from these, there are many other senses which we come across in invertebrates or these are they're also these are said to be the sensory receptors jis ke andar there's there's a sensory receptor which is said to be the tactile receptor that sense touch ke ke jasya hum aur is ke lava yeh pehle hum iski ek enumerate karle ke there's a hydro there's a hygroreceptor that detect content of air ke air ke andar kya kuch hai yeh bhi bahar saarya se invertebrates hai jo ke sense karthe then the geo receptors that sense pull of gravity it also plays very important role for the particularly invertebrates then proprio receptor that respond to compression stretching and bending in tension yeh tamam cheezin jo hai yeh invertebrates ke andar yeh essences hai jis sense ko hum kyaate hai proprio receptors proprio receptors then there's a photo receptor jasak naam se zahra that is that pertains to light then barometer a baroreceptor that respond to pressure changes pressure jas a atmospheric pressure hai jas a hum kyaate hai barometers hota hai jas se wo yeh mayir karate hai isi tara there's a baroreceptor they're sensitive to the pressure then there's a chemo receptors this is mainly concerned with the chemicals aur khast aur pe water bone chemicals water bone aur air bone donu kyunke agar bahothi light concentrate bahothi kum concentration bahothi dilute concentration ki air ki andar ya ya water ki andar chemicals on to yeh invertebrates jo and they can sense them then the photo receptors that is sensitive to light then thermo receptors they are sensitive to temperature changes aur sensory receptors convert stimuli into yeh abhi yeh jitne bhi receptors basicaly vikarte kya hai these sensory receptors agar asal mein yeh jo mukhlif ke samki invertebrates ki andar hum ne receptors ka zekar kya hai yeh bahothi sare aise isi andar hum organs ko koi aise specific organs zoologists jo hai kone hum identify nahin kar sa ke but they are there but they are there lekin yeh ek does still ek a nigma hai ek moema wana hai ki kone se aise kuch aise receptors they respond but they don't have the organs specific organs aise aise hai aise to ek organ hai year is an organ hai lekin nah lekin nah yeh zuri nahi hai ke kuch invertebrates mein khast aur pe ke in wo khast organs ho lekin wo response shows root krte hiya against light now aur receptors they are the transducers that is they convert one form of energy into another form they are transducers so this is very interesting ke wo kisthara transduce krte hiye ek form of energy ko dosi form mein convert krte hiye now all nerve impulses they are same in nature jis kaha hum ne pehle bhi zikar kya nerve impulse kya hai there's a wave of electrochemical change there's a wave of electrochemical change hai lekin iski andar cheese ek hi hai lekin uska response different hota hai now different types of receptors they convert ye yeh jab hum kyaate hai na ke inki nature ek hai wo nature kya hai to different types of receptors jis kabhi hum ne zikar kya they convert different kinds of stimuli into local electrical potential which is called a generator potential to generator potential pehle bantha when generator potential reaches the neuron the threshold potential it causes the channels of ye hum ma apko apko cellular level pehle le jaate hiye threshold potential it causes the channel in plasma membrane to open and create an action potential to wo kyunke there are certain receptors which are responsible jo ke electrical chemical ya koi bhi chemical touch karta hai calcium jo channels hai wo open hu jaate hi aur that creates which is said to be the action potential aur action potential kya hai yeh wo hi hai it is a depolarization now the impulse then travels along during stimulation stimulates stimulate what stimulation we to this impulse then travels along the axon towards a synaptic junction and becomes information going to the cns sent in our system ki taraf ek ek nerve impulse chalti hai to so this is something very interesting ki kistra ek generator potential very action potential mein conversion hoti hai aur wo peh generate action potential then it travels along the neuron to the sent in our system sent in our system se pehle information arti hai towards the effectors and these effectors they may be gland they may be ma they may be muscles or accordingly wo animal pehle spawn karta hai how then in action potential give rise to different sensations animals that have nerve signals from specific receptor always end up in a specific part of brain for interpretation brain ke andar pehle there are different types of there are different there's a variety of you can say the centers when they are stimulated to the information when they are stimulated or accordingly pehle us ke response hota hai for example stimulus that goes to the optic center is interpreted as visual sensation and so on to istra agar wo information to auditory center mein to we will have the sensation of hearing agar wo optic center mein stimulate hota hai yaha wo impal action potential jaata hai wo spectacular part the brain mein to we will have the sensation of that is the veal to istra har brain ke andar there are so many parts there are so many parts when they are stimulated to accordingly that particular information that sense arise hoti hai so yeh brain ke andar yeh mutlif khas thought peh cerebrum mein to bohot saare centers yeh tamam is related hai yeh equilibrium related hai tang related hai peh raja se hum ne pichle modules ke andar sympathetic aur parasympathetic mein bhi zikar kia cranial nerves ka zikar kia to wo cranial nerves hi hai jo ke mutlif ke sum ke inner sensory receptors jo ke sense organs be ke laatehing us ke tara us ke tara jaata hai aur phir accordingly us ke andar phir activity hoti hai to this is again the senses jab tak sense agar koi bhi faraj karein koi bhi sense humari khatum hoja hai to wo particular we cannot enjoy that sense particular li agar hum agar hum faraj karein ke tang ke wo par jo receptors hai wo function nahi karein to wo hum koi cheez koi taste nahi kr sakte wo enjoy nahi kr sakte wo taste ishita agar koi veen problem hojaata hai ya humari aankh ki andar retina ki andar ya humari lens ki andar if it becomes opaque to zaharak we will we will not enjoy won't be able to enjoy the veen the working of the eyes so this is all about this is the introduction of the sensory deception that's all
