| medial wall of middle ear | A bony layer separating the middle from the internal ear or labyrinth; it contains the fenestra vestibuli and the fenestra cochleae. Synonym: paries labyrinthicus cavi tympani, labyrinthine wall of middle ear, medial wall of middle ear. (05 Mar 2000) |
| medial wall of orbit | The thin, rectangular wall of the orbit formed by the orbital plate of the ethmoid, lacrimal, frontal and a small part of the sphenoid bones; the fossa for the lacrimal sac lies at its anterior limit. Synonym: paries medialis orbitae. (05 Mar 2000) |

| cell wall | 1. <cell biology> Extracellular material serving a structural role. 2. <plant biology> In plants the primary wall is pectin rich, the secondary wall mostly composed of cellulose. 3. <microbiology> In bacteria, cell wall structure is complex: the walls of gram-positive and gram-negative bacteria are distinctly different. Removal of the wall leaves a protoplast or spheroplast. (07 Apr 1998) |
| cell wall skeleton | <chemical> A mucoprotein found in the cell wall of various types of bacteria. It has adjuvant and antitumour activities and has been used to augment the production of lymphokine-activated killer (lak) cells. Pharmacological action: adjuvants, immunologic. (12 Dec 1998) |
| membranous wall of middle ear | The wall formed mainly by the tympanic membrane. Synonym: paries membranaceus cavi tympani, lateral wall of middle ear, membranous wall of middle ear. (05 Mar 2000) |
| membranous wall of trachea | The part of the tracheal wall posteriorly that is not reinforced by tracheal cartilages. Synonym: paries membranaceus tracheae. (05 Mar 2000) |
| chest wall | In respiratory physiology, the total system of structures outside the lungs that move as a part of breathing; it includes the rib cage, diaphragm, abdominal wall, and abdominal contents. Synonym: thoracic wall. (05 Mar 2000) |
| chest wall pain | Chest pain that originates from a noncardiac cause. Chest wall pain typically involves an inflammatory condition of the muscles, bones or joints that comprise the thorax. (27 Sep 1997) |
