Endocrien stelsel
« Communicatie via hormonen
« Homeostase handhaven -> reguleren activiteit v. cellen, weefsels, organen,…
« Negatieve feedback

Zenuwstelsel
o Snelle reactie via chemische signaalstoffen ( neurotransmitters), die aan receptoren binden

Endocrien stelsel
o Trage reactie, maar langdurig effect door chemische signaalstoffen ( hormonen)
o Verplaatsing via bloed naar specifieke doelcellen/receptoren
- receptoren op het celmembraan
- receptoren intracellulair

Endocriene cellen
 Klierproduct afgeven aan extracellulaire vloeistof
 Cytokinen = enkel invloed op buurcellen (prostaglandines)


T4  reguleren Ca2+-metabolisme

Alvleesklier = pancreas
- exocrien : verteringsenzymen
- endocrien : glucagon & insuline

Thymus
Maakt hormonen die productie
immuun cellen stimuleren

ormonale activiteit via negatieve feedback
 Hormonale activiteit door;
- Humorale prikkels -> verandering in samenstelling v. extracellulaire vloeistof
- Hormonale prikkels
- Neurale prikkels -> neurotransmitters tussen zenuwen & klier
-> bv; activiteit v. hypothalamus want dit vormt de verbinding tussen
zenuw-en endocrien stelsel
