| tracheal ring | The 16 to 20 incomplete rings of hyaline cartilage forming the skeleton of the trachea; the rings are deficient posteriorly for from one-fifth to one-third of their circumference. Synonym: cartilagines tracheales, tracheal ring. (05 Mar 2000) |

| tracheal triangle | The triangle bounded by the sternocleidomastoid muscle, the superior belly of the omohyoid muscle, and the anterior midline of the neck; the infrahyoid muscles occupy most of it. Synonym: trigonum musculare, trigonum omotracheale, inferior carotid triangle, omotracheal triangle, tracheal triangle. (05 Mar 2000) |
| tracheal tube | A flexible tube inserted nasally, orally, or through a tracheotomy into the trachea to provide an airway, as in tracheal intubation. Synonym: endotracheal tube, intratracheal tube. (05 Mar 2000) |
| tracheal tug | A downward pull of the trachea, manifested by a downward movement of the thyroid cartilage, synchronous with the action of the heart and symptomatic of aneurysm of the aortic arch; the sign is elicited most easily by drawing the cricoid cartilage upward with the thumb and forefinger while the patient sits with head thrown back and mouth closed, a jerky type of inspiration seen when the intercostal muscles and the sternocostal parts of the diaphragm are paralysed by deep general anaesthesia or muscle relaxants; due to the unopposed action of the crura pulling on the dome of the diaphragm and thence on the pericardium, lung roots, and tracheobronchial tree during each inspiration. (05 Mar 2000) |
| tracheal ulceration | Erosion of the tracheal mucous membrane with, in some cases, exposure of the rings, at the site at which a cuffed tracheostomy tube has been present for some time. (05 Mar 2000) |
| tracheal veins | Several small venous trunks from the trachea, emptying into the brachiocephalic veins or the superior vena cava. Synonym: venae tracheales. (05 Mar 2000) |

| anterior wall of middle ear | It contains the carotid canal and the opening of the auditory tube. Synonym: paries caroticus cavi tympani, anterior wall of middle ear, carotid wall of middle ear. (05 Mar 2000) |
| anterior wall of stomach | The part of the gastric wall that faces the peritoneal cavity. Synonym: paries anterior gastris. (05 Mar 2000) |

| anterior wall of vagina | It is somewhat shorter than the posterior wall and at its upper end is penetrated by the cervix of the uterus. Synonym: paries anterior vaginae. (05 Mar 2000) |
| beam-wall reaction | <radiobiology> Fusion reaction which occurs from the collision of a fast beam ion with an ion embedded in or adsorbed onto the reactor wall. (09 Oct 1997) |
| carotid wall of middle ear | It contains the carotid canal and the opening of the auditory tube. Synonym: paries caroticus cavi tympani, anterior wall of middle ear, carotid wall of middle ear. (05 Mar 2000) |
| parietal wall | The body wall or the somatopleure from which it is formed. (05 Mar 2000) |
| mastoid wall of middle ear | It contains the opening into the mastoid antrum. Synonym: paries mastoideus cavi tympani, mastoid wall of middle ear, posterior wall of middle ear. (05 Mar 2000) |
