it just means its not in the front, and in the back.
I think you mean tbl (L instead of 1), which is to knit through the back loop. (Regular knit stitch is through the front loop).
This is a term used in pregnancy to describe the placenta positioning. Grade two posterior placenta means that the placenta is facing the back of the uterus. It is located in the lower segment and touching the edge of the cervical opening but is not completely covering it.
It means that your placenta is in the front of your uterus. This is not an issue in early pregnancy as the placenta usually moves as pregnancy progresses. If it is still anterior near end of pregnancy it can make you have to have a C-section. Also, it will be harder to feel the baby's kicks and movement as an anterior placenta cushions the baby from the tummy.

It is called an anterior placenta which means the placenta is attached to the front wall of your uterus (rather than the back wall which is more common). It doesn't mean anything other than there is a little extra cushioning between the wall of your uterus and your baby so you probably won't feel baby's first movements until a little later into your pregnancy (probably around 20 weeks or more if you are also overweight).
It means the placenta is located in the posterior wall of uterus
If your cervix is closed in the front but open in the back, this might mean you are about to start your period. It could also mean that you are ovulating.
