Contig map: A map depicting the relative order of a linked library of small overlapping clones representing a complete chromosome segment.
A contig is a chromosome map showing the locations of those regions of a chromosome where contiguous DNA segments overlap. Contig maps are important because they provide the ability to study a complete, and often large, segment of the genome by examining a series of overlapping clones which then provide an unbroken succession of information about that region.
- Contiguous gene syndrome
Contiguous gene syndrome: A disorder due to deletion of multiple gene loci that are adjacent to one another. Contiguous gene syndromes are characterized by multiple, apparently unrelated, clinical features caused by deletion of the multiple adjacent genes. Each of the individual genes within a contiguous region, when mutated, gives rise to a distinct feature. An […]
- Continuous passive motion machine
Continuous passive motion machine: A machine used to help rehabilitate a limb (an arm or leg). The continuous passive motion (CPM) machine is attached to, for example, a knee that has had surgery. The CPM machine then constantly moves the knee through a range of motion for a period of time while the patient relaxes.
- Contraceptive device, intrauterine (IUD)
A device inserted into the uterus (womb) to prevent conception (pregnancy). The IUD can be a coil, loop, triangle, or T in shape made of plastic or metal. An IUD is inserted into the uterus by a health care professional. Of two types of IUDs approved in the U.S., one can remain in place for […]
- Contraceptive sponge, vaginal
Contraceptive sponge, vaginal: A contraceptive device that is donut-shaped, made of plastic, contains a spermicide (nonoxynol-9) and is inserted into the vagina to cover the cervix. A loop is provided to ease removal. The sponge protects against contraception for up to 24 hours and for multiple acts of intercourse within this time. It is left […]
- Contraceptive, combined oral
Contraceptive, combined oral: Commonly called “the pill,” combined oral contraceptives are the most commonly used form of reversible birth control in the United States. This form of birth control suppresses ovulation (the monthly release of an egg from the ovaries) by the combined actions of the hormones estrogen and progestin. If a woman remembers to […]
