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.
1 Subtotal hysterectomy is the removal of the uterus, leaving the cervix in place. It is also known as supracervical or partial hysterectomy.  Radical hysterectomy is the removal of the uterus, cervix, ovaries, structures that support the uterus, and sometimes the lymph nodes.
