Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship:
Total hysterectomyâThe entire uterus, including the cervix, is removed. Supracervical (also called subtotal or partial) hysterectomyâThe upper part of the uterus is removed, but the cervix is left in place. This type of hysterectomy can only be performed laparoscopically or abdominally.
Hysterectomy, removal of the uterus, can be performed through an abdominal incision, an incision at the top of the vagina, or laparoscopically through a few small (1/2 inch) incisions in the abdomen. Total hysterectomy removes the entire uterus, including the cervix.
