i meccanocettori

I meccanocettori sono recettori sensoriali presenti in quasi tutto il corpo. Essi sono deputati alle percezioni cutanee, pressorie (cardiache e vascolari), distensive viscerali e masticatorie e sono piccolissimi.

La vista è il senso che ci permette di distinguere tutto ciò che osserviamo. l'occhio è la "sede" del senso della vista ed è un organo molto sensibile

la vista

nelll'occhio si trovano 2 cavità dentro cui c'è il bulbo.il bulbo ha un diametro di 2,5cm e si muove grazie a 6 muscoli.

i fotocettori

CHEMIOCETTORe(CHEMIORECETTORE,CHEMORECETTORE)

Un chemiocettore, è un recettore sensoriale, un organello microscopico costituito da terminazioni nervose che rispondono a stimoli chimici. Essi sono alla base di alcuni sensi quali il gusto e l'olfatto. Sono esempi di chemiorecettori le cellule dei glomi, i recettori gustativi ed olfattivi.

BASTONCELLI: Sono più sensibili dei coni,non permettono la visione dei colori ma servono alla visione notturna, sono numerosi e distribuiti nella retina

CONI:Hanno la responsabilità della memoria diurna e dei colori sono men, si trovano nella retina e sono concentrati nella fovea

CONI E BASTONCELLI

ilNell'occhio si trovano dei fotorecettori: CONI E BASTONCELLI

l'udito

l'udito è il senso che ci permette di percepire le onde sonore generate dalla vibrazione di un corpo e trasmette attraverso l'aria

le malattie della vista

Cataratta: È la causa principale di cecità in tutto il mondo . Si verifica quando il cristallino dell'occhio diventa opaco . Glaucoma: Una malattia che danneggia il nervo ottico a causa di un'elevata pressione interna all'occhio . Retinopatia diabetica: Causata dal diabete, può portare a danni alla retina e perdita della vista . Miopia: Una condizione in cui gli oggetti vicini sono visti chiaramente, ma quelli lontani appaiono sfocati. Ipermetropia: L'opposto della miopia, dove gli oggetti lontani sono visti chiaramente, ma quelli vicini sono sfocati. Astigmatismo: Una condizione in cui l'occhio ha una forma irregolare, causando visione sfocata. Uveite: Un'infiammazione dell'uvea, la parte media dell'occhio. Congiuntivite: Un'infiammazione della congiuntiva, il tessuto che ricopre la superficie interna delle palpebre e quella anteriore del bulbo oculare

Equilibrio

IL SENSO DELL'equilibrio ci aiuta a regolare la nostra posizione e anche a rimanere in equilibrio.Dentro l'orecchio interno abbiamo 3 canali semicircolari che sono perpendicolari tra loro alla base dei canti abbiamo dei gruppi di cellule sensoriali ciliate che sono immerse in un liquido gelatinoso chiamato OTOLITI.

L'OLFATTO

il senso dell'olfatto ci permette di percepire gli odori ,questo senso è affidato a un gruppo di chemocettori Le cellule olfattive hanno due prolungamento uno verso l'alto e uno verso il basso

COME FUNZIONA L' OLFATTO?

Nell`aria che circola nelle cavità nasali si trovano numerose molecole che si dissolvono nello strato di muco e vengono in contatto con i peli olfattivi .un volta eccitati generano uno stimolo a seconda della chimica della sostanza lo stimolo raggiunge un'areadella corteccia celebrale dove viene riconosciuto grazie a esperienze precedenti si annusamento e conservato in un archivio

termocettori

I termocettori sono recettori sensoriali che permettono di percepire la temperatura

si attivano sopra i 30 °C per mandare segnali di calore al sistema nervoso centrale, ma arrivati a 45 °C cessano di funzionare

attraverso i termocettori profondi è possibile misurare la temperatura corporea interna

We don't like to bore. We don't want to be repetitive. Communicating the same way is boring and doesn't engage. We do it differently. We sabotage boredom. We create what the brain likes to consume becauseit stimulates it.
