Definition of trabecula in English: trabeculanounPlural trabeculae trəˈbɛkjʊlətrəˈbɛkjələ 1Anatomy
Each of a series or group of partitions formed by bands or columns of connective tissue, especially a plate of the calcareous tissue forming cancellous bone. 〔剖〕小梁，小柱 Example sentencesExamples - Note the presence of numerous osteoclasts lining the bone trabeculae.
- The cistern is traversed by delicate connective tissue trabeculae, which bridge across the interval between the arachnoid mater and the pia mater.
- An atypical hydronephrotic type may have isolated ureteral atresia with multiple cysts communicating with a dilated renal pelvis with dysplastic renal tissue forming trabeculae between the cysts.
- Histologic study demonstrated a fibro-osseous lesion with woven bone trabeculae and bland-looking fibrous tissue.
- In such calculations, however, bone matrix is usually approximated as an isotropic material, and anisotropic mechanical properties result from a preferred orientation of the trabeculae in cancellous bone.
2Botany
Any of a number of rodlike structures in plants, e.g. a strand of sterile tissue dividing the cavity in a sporangium. 〔植〕径列条，横隔片，横条 Example sentencesExamples - No dots can be detected in the vacuoles but the tonoplast and the transvacuolar trabeculae of cytoplasm are labelled demonstrating that actin is present at this level.
- Locally there are ‘hints’ of a parallel fibrous, possibly spicular, structure in the normally irregularly crystalline microstructure of the trabeculae.
- Together with additional stereome, these trabeculae cover dissepimentarium completely, so no reliable information on structure of dissepimentarium is available.
- The resulting septal trabeculae are thick with regularly produced lateral branches.
- Special attention was paid to the structure and pattern of the distribution of septal trabeculae.
Derivativesadjective Overall morphology was judged to be well preserved by this dissection protocol, and was comparable to that observed in previous preparations where only the inner wall and underlying trabecular meshwork were harvested. Example sentencesExamples - Furthermore, no immunostained cells are detectable even in the solid and trabecular patterns within some canalicular adenomas, again contrasting with the basal cell adenoma variants with similar patterns.
- In particular, the influence of bone mass distribution in cancellous bone, which mainly results from the trabecular architecture, can be predicted fairly accurately using finite element calculations.
- The spongy appearance is misleading, because careful examination of the architecture reveals a highly organized trabecular system providing maximal structural support with minimal density of bony tissue.
- With a dental curette, the trabecular bone was scraped out of both cortical shells, combined and put into 5% trichloroacetic acid.
adjectivetrəˈbɛkjʊlət Octoblepharum cylindricum differs from O. albidum by its longer setae, cylindrical capsules, entire leaf apices, and strongly trabeculate peristome teeth. Example sentencesExamples - The teeth are equally thickened and less prominently trabeculate on both adaxial and abaxial sides.
- An insulin formulation with porous, spherical calcium carbonate composed of trabeculate or needle-shaped crystals, or an aggregation of the parallel intergrowth of these forms, as its carrier, will be presented.
- The capsule lacks stomata and on the outside has a trabeculate appearance due to the outermost cells having thickened lateral walls.
