| tela | 1. Any thin weblike structure. 2. A tissue; especially one of delicate formation. Origin: L. A web (05 Mar 2000) |
| tela conjunctiva | <pathology> Rather general term for mesodermally derived tissue that may be more or less specialised. Cartilage and bone are specialised connective tissue, as is blood, but the term is probably better reserved for the less specialised tissue that is rich in extracellular matrix (collagen, proteoglycan etc.) and that surrounds other more highly ordered tissues and organs. (18 Nov 1997) |
| tela elastica | A form of connective tissue in which the elastic fibres predominate; it constitutes the ligamenta flava of the vertebrae and the ligamentum nuchae, especially of quadrupeds; it occurs also in the walls of the arteries and of the bronchial tree, and connects the cartilages of the larynx. Synonym: elastica, tela elastica. (05 Mar 2000) |
| tela subcutanea | A loose fibrous envelope beneath the skin, containing fat in its meshes (panniculus adiposus) or fasciculi of muscular tissue (panniculus carnosus); it contains the cutaneous vessels and nerves and is in relation by its undersurface with the deep fascia. Synonym: fascia superficialis, tela subcutanea, hypoderm, hypodermis, stratum subcutaneum, subcutis. (05 Mar 2000) |
| tela submucosa | A layer of tissue beneath a mucous membrane. The layer of connective tissue beneath the tunica mucosa. Synonym: tela submucosa, tunica submucosa. (05 Mar 2000) |
| tela submucosa pharyngis | The fibrous coat of the pharyngeal wall situated between the mucous and muscular coats; it is attached above to the basilar part of the occipital bone, and the petrous part of the temporal bone. This layer and the mucosa which lines it forms the wall of the non-muscular pharynx (pharyngeal vault) above the superior pharyngesl constrictor muscle. Synonym: fascia pharyngobasilaris, aponeurosis pharyngea, tela submucosa pharyngis. (05 Mar 2000) |
| tela subserosa | The layer of connective tissue beneath a serous membrane such as that of the periconeum or pericardium. Synonym: tela subserosa. (05 Mar 2000) |
| tela vasculosa | <radiology> Formed by the invagination of ependyma into ventricles CP of lateral and third ventricles are continuous, extends posteriorly to temporal horn, 3rd and two lateral ventricles continuous at interventricular foramen CP of fourth ventricle is seperate, shape of a T, vertical limb extends from near Magendie's foramen to the fastigium, horizontal limbs project into cerebellopontine angle cisterns the glomus is a localised enlargement of CP, found at the posterior part of the floor of the ventricle (12 Dec 1998) |
| tenia choroidea | The somewhat thickened line along which a choroid membrane or plexus is attached to the rim of a brain ventricle. Synonym: tenia telae. Teniae coli, the three bands in which the longitudinal muscular fibres of the large intestine, except the rectum, are collected; these are the mesocolic tenia, situated at the place corresponding to the mesenteric attachment; the free tenia, opposite the mesocolic tenia; and the omental tenia, at the place corresponding to the site of adhesion of the greater omentum to the transverse colon. Synonym: bands of colon, colic teniae, teniae of Valsalva. (05 Mar 2000) |
| fissura choroidea | The narrow cleft along the medial wall of the lateral ventricle along the margins of which the choroid plexus is attached; it lies between the upper surface of the thalamus and lateral edge of the fornix in the central part of the ventricle and between the terminal stria and fimbria hippocampi in the inferior horn. Synonym: fissura choroidea. (05 Mar 2000) |
| lamina choroidea | The layer of modified ependymal cells that forms the inner layer of the tela choroidea, facing the ventricle. Synonym: lamina epithelialis, epithelial choroid layer, lamina choroidea epithelialis, lamina choroidea. (05 Mar 2000) |
| lamina choroidea epithelialis | The layer of modified ependymal cells that forms the inner layer of the tela choroidea, facing the ventricle. Synonym: lamina epithelialis, epithelial choroid layer, lamina choroidea epithelialis, lamina choroidea. (05 Mar 2000) |
| apertura lateralis ventriculi quarti | One of the two lateral openings of the fourth ventricle into the subarachnoid space at the cerebellopontine angle. Synonym: apertura lateralis ventriculi quarti, foramen lateralis ventriculi quarti, foramen of Key-Retzius, foramen of Luschka, Retzius' foramen. (05 Mar 2000) |
| apertura mediana ventriculi quarti | The large midline opening in the posterior inferior part of the roof of the fourth ventricle, connecting the ventricle with the cerebellomedullary cistern. Synonym: apertura mediana ventriculi quarti, arachnoid foramen, Magendie's foramen, median aperture of the fourth ventricle. (05 Mar 2000) |
