Masno tkivo
 MORFOLOGIJA
-Veliku citoplazmatsku masnu
kapljicu (do 120 mikrometara)
Spljošteno periferno postavljeno
jedro
 FUNKCIJA
Izvor energije: Sinteza,
deponovanje i oslobađanje
masti
Zaštita
ADIPOCITI
(Belo masno tkivo)
 GOJAZNOST
HIPERTROFIČNA
(Uvećanje ćelija)
HIPERPLASTIČNA
(Povećava se broj ćelija)
Adipociti se normalno ne dele
posle ranog detinjstva, tako da
je gojaznost najčešće
HIPERTROFIČNA.
Eksktremna gojaznost može biti
HIPERPLASTIČNA
