| cervical hygroma | A benign cystic overgrowth of lymphatics of the neck, present at birth, which may form a large tumour-like mass. Synonym: cervical hygroma. (05 Mar 2000) |
| cervical hyperesthesia | The hypersensitivity of teeth in the cervical area due to exposure of the dentin. (05 Mar 2000) |
| cervical iliocostal muscle | <anatomy, muscle> Origin, angles of upper six ribs; insertion, transverse processes of middle cervical vertebrae; action, extends, abducts, and rotates cervical vertebrae; nerve supply, dorsal branches of upper thoracic nerves. Synonym: musculus iliocostalis cervicis, cervical iliocostal muscle, cervicalis ascendens, musculus cervicalis ascendens. (05 Mar 2000) |
| cervical interspinales muscles | Origin, tubercle of spinous process of cervical vertebra; insertion, tubercle of spinous process of next superior vertebra; action, extends the neck; nerve supply, dorsal rami of cervical nerves. Synonym: musculus interspinalis cervicis, cervical interspinal muscle. (05 Mar 2000) |
| cervical interspinal muscle | Origin, tubercle of spinous process of cervical vertebra; insertion, tubercle of spinous process of next superior vertebra; action, extends the neck; nerve supply, dorsal rami of cervical nerves. Synonym: musculus interspinalis cervicis, cervical interspinal muscle. (05 Mar 2000) |
| cervical intraepithelial neoplasia | A term which describes precancerous changes to the epithelial cells lining the cervix. The diagnosis is made from the microscopic examination of a PAP smear acquired tissue specimen. Less than 5% of all PAP smears will show cervical dysplasia. The peak incidence is in women 25 to 35 years of age. Risk factors include multiple sexual partners, early onset of sexual activity (less than 18), early childbearing (less than 16) and past medical history of a sexually transmitted disease (for example genital warts, genital herpes, HIV infection). Treatment is based on the degree of dysplasia present, as judged by a pathologist. Treatments include cryotherapy and conisation. Origin: Gr. Plassein = to form (27 Sep 1997) |
| cervical laminectomy | <procedure, surgery> A surgical procedure which is designed to relieve pressure on the spinal cord or nerve root that is being caused by a slipped or herniated disk in the cervical spine. This procedure includes removal of a portion of the bone comprising a vertebra. Recovery is generally 7-10 days. (27 Sep 1997) |
| cervical ligament of uterus | <anatomy> A fibrous band attached to the uterine cervix and the vault of the lateral fornix of the vagina; continuous with the tissue ensheathing the pelvic vessels. Synonym: cervical ligament of uterus, ligamentum transversale colli, Mackenrodt's ligament. (05 Mar 2000) |
| cervical line | A continuous anatomical irregular curved line marking the cervical end of the crown of a tooth and the cementoenamel junction. (05 Mar 2000) |
| cervical longissimus muscle | <anatomy, muscle> Origin, transverse processes of upper thoracic vertebrae; insertion, transverse processes of middle and upper cervical vertebrae; action, extends cervical vertebrae; nerve supply, dorsal primary rami of lower cervical and upper thoracic spinal nerves. Synonym: musculus longissimus cervicis, cervical longissimus muscle, musculus transversalis cervicis, musculus transversalis colli. (05 Mar 2000) |
| cervical loop | A loop in the cervical plexus consisting of fibres from the first three cervical nerves. Fibres from a loop between the C-1 and C-2 spinal nerves accompany the hypoglossal nerve for a short distance, leaving it as the superior root of the ansa cervicalis. Fibres from a loop between the C-2 and C-3 spinal nerves form the inferior root of the ansa cervicalis. Most commonly, the roots merge, forming the ansa cervicalis, which gives rise to branches innervating infrahyoid muscles. Synonym: cervical loop, loop of hypoglossal nerve. (05 Mar 2000) |
| cervical lymphadenitis | <pathology> Refers to inflammation of the lymph glands in the neck. Often occurs secondary to a viral or bacterial (Streptococcus) infection. Common symptoms include pain and tenderness to the swollen lymph glands in the neck. Cervical lymphadenitis may accompany tonsillitis, pharyngitis and dental infections. (27 Sep 1997) |
| cervical margin | Termination of a restoration in the gingival area. (05 Mar 2000) |
| cervical margin of tooth | The slightly constricted part of a tooth, between the crown and the root. Synonym: cervix dentis, cervical margin of tooth, cervical zone of tooth, collum dentis, dental neck. (05 Mar 2000) |
