| long-tongue | torticollis Previous: writing, writing hand, wrongful life, wrought wire, wrybill, wrymouthNext: wry neck, wuchereria, wuchereria bancrofti, Wuchereria malayilong-tongue -->wry 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.

| alveolar dead space | The difference between physiologic dead space and anatomical dead space; it represents that part of the physiologic dead space resulting from ventilation of relatively underperfused or nonperfused alveoli; it differs specifically in being placed so as to fill and empty in parallel with functional alveoli, rather than being interposed in the conducting tubes between functional alveoli and the external environment. (05 Mar 2000) |
| anatomical dead space | The volume of the conducting airways from the external environment (at the nose and mouth) down to the level at which inspired gas exchanges oxygen and carbon dioxide with pulmonary capillary blood; formerly presumed to extend down to the beginning of alveolar epithelium in the respiratory bronchioles, but more recent evidence indicates that effective gas exchange extends some distance up the thicker-walled conducting airways because of rapid longitudinal mixing. Compare: alveolar dead space, physiologic dead space. Synonym: anatomical airway. (05 Mar 2000) |
| antecubital space | The fossa in front of the elbow, bounded laterally and medially by the humeral origins of the extensors and flexors of the forearm, respectively, and superiorly by an imaginary line connecting the humeral condyles.
