| annular cartilage | <anatomy> The lower most of the laryngeal cartilages, may be palpated just below the thyroid prominence Adjacent the cricoid cartilage and the first tracheal ring is the cricothyroid membrane, a site used for rapid emergency airway access (cricothyroidotomy). (13 Nov 1997) |
|---|---|
| apex of arytenoid cartilage | The pointed upper end of the cartilage which supports the corniculate cartilage and the aryepiglottic fold. Synonym: apex cartilaginis arytenoideae. (05 Mar 2000) |
| arch of cricoid cartilage | The narrow part of the cartilage that encircles the air passage anterior to the lamina. Synonym: arcus cartilaginis cricoideae. (05 Mar 2000) |
| arcuate crest of arytenoid cartilage | The ridge on the anterior surface of the arytenoid cartilage that separates the triangular from the oblong fovea. Synonym: crista arcuata cartilaginis arytenoideae, arched crest, arcuate crest. (05 Mar 2000) |
| arthrodial cartilage | The cartilage covering the articular surfaces of the bones participating in a synovial joint. Synonym: cartilago articularis, arthrodial cartilage, diarthrodial cartilage, investing cartilage. (05 Mar 2000) |
| arytenoid cartilage | One of a pair of small pyramidal cartilages that articulate with the lamina of the cricoid cartilage. The corresponding vocal ligament and several muscles are attached to it. (12 Dec 1998) |
| auricular cartilage | The cartilage of the auricle. Synonym: cartilago auriculae, cartilage of ear, conchal cartilage. (05 Mar 2000) |
| base of arytenoid cartilage | The part of the arytenoid cartilage that articulates with the cricoid cartilage and from which the muscular process extends laterally and the vocal process projects anteriorly. Synonym: basis cartilaginis arytenoideae. (05 Mar 2000) |
| basilar cartilage | The cartilage filling the foramen lacerum. Synonym: basilar fibrocartilage, fibrocartilago basalis. (05 Mar 2000) |
| calcified cartilage | Cartilage in which calcium salts are deposited in the matrix; it occurs prior to replacement by osseous tissue and sometimes in aging cartilage. (05 Mar 2000) |
| mandibular cartilage | A cartilage bar in the mandibular arch that forms a temporary supporting structure in the embryonic mandible; the cartilagenous primordia of the malleus and incus develop from its proximal end, and it also gives rise to the sphenomandibular and anterior malleolar ligaments. Synonym: Meckel's cartilage. (05 Mar 2000) |
| parachordal cartilage | Cartilage primordia adjacent on either side to the cephalic portion of the notochord in young embryos; they represent an initial step in the formation of the chondrocranium. (05 Mar 2000) |
| paraseptal cartilage | A narrow strip of cartilage located between the lower edge of the cartilage of the nasal septum and the vomer. Synonym: Jacobson's cartilage, paraseptal cartilage, vomer cartilagineus, vomerine cartilage, vomeronasal cartilage. (05 Mar 2000) |
| parenchymatous cartilage | An embryonic or immature stage of cartilage in which it consists chiefly of cells with very little matrix. Synonym: parenchymatous cartilage. (05 Mar 2000) |
| cartilage | <pathology> Connective tissue dominated by extracellular matrix containing collagen type II and large amounts of proteoglycan, particularly chondroitin sulphate. Cartilage is more flexible and compressible than bone and often serves as an early skeletal framework, becoming mineralised as the animal ages. Cartilage is produced by chondrocytes that come to lie in small lacunae surrounded by the matrix they have secreted. (18 Nov 1997) |
