Cervical Atlas
|
D001270 |
[An anatomical variant of the cervical atlas in which osseous bridges connect posterior superior articular process to the posterior arch thereby covering grooves for the VERTEBRAL ARTERY.
, The first cervical vertebra.

|
Cervical Cord
|
D066193 |
[The segment of the spinal cord within the CERVICAL VERTEBRAE.
] |
|
Cervical Intraepithelial Neoplasia
|
D018290 |
[A malignancy arising in uterine cervical epithelium and confined thereto, representing a continuum of histological changes ranging from well-differentiated CIN 1 (formerly, mild dysplasia) to severe dysplasia/carcinoma in situ, CIN 3. The lesion arises at the squamocolumnar cell junction at the transformation zone of the endocervical canal, with a variable tendency to develop invasive epidermoid carcinoma, a tendency that is enhanced by concomitant human papillomaviral infection. (Segen, Dictionary of Modern Medicine, 1992)

Cervical Length Measurement
|
D054791 |
[A parameter usually used in PRENATAL ULTRASONOGRAPHY to measure the length of the uterine neck (CERVIX UTERI). Cervical length or its shortening is used to identify and prevent early cervical opening and PRETERM BIRTH.
] |
|
Cervical Plexus
|
D002572 |
[A network of nerve fibers originating in the upper four CERVICAL SPINAL CORD segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head. It also distributes motor fibers to muscles of the cervical SPINAL COLUMN, infrahyoid muscles, and the DIAPHRAGM.

|
Cervical Plexus Block
|
D066008 |
[A blocking of NEURAL CONDUCTION in the network of nerve fibers innervating the neck and shoulder.
] |
|
Cervical Rib
|
D057070 |
[A supernumerary rib developing from an abnormal enlargement of the costal element of the C7 vertebra. This anomaly is found in 1-2% of the population and can put pressure on adjacent structures causing CERVICAL RIB SYNDROME; THORACIC OUTLET SYNDROME; or other conditions.
] |
|
Cervical Rib Syndrome
|
D002573 |
[A condition associated with compression of the BRACHIAL PLEXUS; SUBCLAVIAN ARTERY; and SUBCLAVIAN VEIN at the thoracic outlet and caused by a complete or incomplete anomalous CERVICAL RIB or fascial band connecting the tip of a cervical rib with the first thoracic rib. Clinical manifestations may include pain in the neck and shoulder which radiates into the upper extremity, PARESIS or PARALYSIS of brachial plexus innervated muscles; sensory loss; PARESTHESIAS; ISCHEMIA; and EDEMA. (Adams et al., Principles of Neurology, 6th ed, p214)

|
Cervical Ripening
|
D020070 |
[A change in the CERVIX UTERI with respect to its readiness to relax. The cervix normally becomes softer, more flexible, more distensible, and shorter in the final weeks of PREGNANCY. These cervical changes can also be chemically induced (LABOR, INDUCED).
] |
|
Cervical Vertebrae
|
D002574 |
[The first seven VERTEBRAE of the SPINAL COLUMN, which correspond to the VERTEBRAE of the NECK.
] |
|
Cervicoplasty
|
D044964 |
[Reconstructive surgical procedures in the NECK region to restore or improve form and function.
] |
|
Cervix Mucus
|
D002582 |
[A slightly alkaline secretion of the endocervical glands. The consistency and amount are dependent on the physiological hormone changes in the menstrual cycle. It contains the glycoprotein mucin, amino acids, sugar, enzymes, and electrolytes, with a water content up to 90%. The mucus is a useful protection against the ascent of bacteria and sperm into the uterus. (From Dictionary of Obstetrics and Gynecology, 1988)

|
Cervix Uteri
|
D002584 |
[The neck portion of the UTERUS between the lower isthmus and the VAGINA forming the cervical canal.
] |
|
Cesarean Section
|
D002585 |
[Extraction of the FETUS by means of abdominal HYSTEROTOMY.
] |
|
Cesarean Section, Repeat
|
D017604 |
[Extraction of the fetus by abdominal hysterotomy anytime following a previous cesarean.
] |
|
Cesium
|
D002586 |
[A member of the alkali metals. It has an atomic symbol Cs, atomic number 50, and atomic weight 132.91. Cesium has many industrial applications, including the construction of atomic clocks based on its atomic vibrational frequency.
] |
|
Cesium Isotopes
|
D002587 |
[Stable cesium atoms that have the same atomic number as the element cesium, but differ in atomic weight. Cs-133 is a naturally occurring isotope.
] |
|
Cesium Radioisotopes
|
D002588 |
[Unstable isotopes of cesium that decay or disintegrate emitting radiation. Cs atoms with atomic weights of 123, 125-132, and 134-145 are radioactive cesium isotopes.
] |
|
Cestoda
|
D002589 |
[A subclass of segmented worms comprising the tapeworms.
] |
|
Cestode Infections
|
D002590 |
[Infections with true tapeworms of the helminth subclass CESTODA.
