A trimpot or trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits. When they are used as a variable resistance (wired as a rheostat) they are called preset resistors.
Gynecologists specialize in the female reproductive system, but also care for women's overall health. A gynecologist is a doctor who treats medical conditions and diseases that affect women and their reproductive organs. (Gynecologists are also trained in obstetrics-the care of women during pregnancy and childbirth, which overlaps with gynecology.) 2.
Providing female health care, with an emphasis on reproductive organs, is the focus of gynecology. Prenatal care and pregnancy support are the primary functions of obstetrics. A gynecologist helps women lead healthy lives through regular check-ups and preventative care, and an obstetrician helps women have healthy pregnancies.
