Dar ce este exact acest filtrum si de ce il avem cu totii? Potrivit site-ului IFL science, filtrumul se afla in stransa legatura cu modul in care chipul capata contur in perioada de dezvoltare intrauterina. Filtrumul marcheaza un punct de jonctiune, fiind locul in care se unesc cele doua jumatati ale fetei, a explicat Dr. Michael Mosley intr-un videoclip din cadrul programului televizat Inside the Human Body (In interiorul corpului omenesc), prezentat de postul BBC.
In primele stagii de dezvoltare, chipul omenesc este alcatuit din trei sectiuni principale, care se intalnesc la nivelul buzei superioare, formand astfel zona depresionara denumita filtrum.
Dezvoltarea faciala a craniului are loc intre cea de-a doua si cea de-a treia luna de viata uterina, iar daca pe durata acestei perioade intervin tulburari de dezvoltare a fizionomiei faciale, determinate de factori genetici, de exemplu, filtrumul nu se mai formeaza niciodata.
