What an anterior Cervix????

So I had my dr appt. I'm 37 weeks. She checked my cervix, she said can feel my baby head but my cervix is still closed for business. She also said I had anterior cervix, that she didn't need to put her fingers too far because my cervix was right there.
I'm still not sure what anterior cervix really means.
I know  everyone women have different size of uterus and their positions are different like tilted etc.
I'm trying understand what is anterior cervix and the reasoning of that position?
