| promoter regions | <genetics> DNA sequences which are recognised (directly or indirectly) and bound by a DNA-dependent RNA polymerase during the initiation of transcription. Highly conserved sequences within the promoter include the pribnow box in bacteria and the tata box in eukaryotes. (12 Dec 1998) |

| anterior region of neck | The area of the neck bounded by the mandible, the anterior border of the sternocleidomastoid muscle, and the anterior midline of the neck; it is subdivided into carotid, muscular, submandibular, and submental triangles.

| radical neck dissection | The most commonly performed major operation for head and neck malignancies, most of which are squamous cell carcinomas. The neck is opened laterally, the majority of the sternocleidomastoid muscle is removed, as are the regional cervical lymph nodes, the jugular vein, the spinal accessory nerve, the submaxillary gland and most of the parotid gland. There are several modifications. (12 Dec 1998) |

| wry neck | torticollis Previous: writing, writing hand, wrongful life, wrought wire, wrybill, wrymouthNext: wry neck, wuchereria, wuchereria bancrofti, Wuchereria malayiwry neck 1. A twisted or distorted neck; a deformity in which the neck is drawn to one side by a rigid contraction of one of the muscles of the neck; torticollis. Medically called spasmodic torticollis, or torticollis. The most common of the focal dystonias. In torticollis, the muscles in the neck that control the position of the head are affected, causing the head to twist and turn to one side. In addition, the head may be pulled forward or backward. 2. <ornithology> Any one of several species of Old World birds of the genus Jynx, allied to the woodpeckers; especially, the common European species (J. Torguilla); so called from its habit of turning the neck around in different directions. Synonym: cuckoo's mate, snakebird, summer bird, tonguebird, and writheneck.
