| Anatomical terminology |
The amniotic sac is the sac in which the fetus develops.
Some sources consider it to be equivalent to the amnion,[1][2], while other sources consider it to consist of the amnion and the chorion.[citation needed]
It is also called the amniotic bubble because of its resemblance to a bubble. [citation needed]
When in the light, the amniotic sac is shiny and very smooth, but too tough to pierce through.
Amniotomy
An artificial rupture of membranes (ARM), also known as an amniotomy, may be performed by a midwife or obstetrician. This is usually performed using an amnihook and is intended to induce or accelerate labour.
