Definición de trabecula en inglés:

sustantivo (plural trabeculae trəˈbɛkjʊliː)

1 Anatomy 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.
Oraciones de ejemplo
  • The cistern is traversed by delicate connective tissue trabeculae, which bridge across the interval between the arachnoid mater and the pia mater.
  • 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.
  • Histologic study demonstrated a fibro-osseous lesion with woven bone trabeculae and bland-looking fibrous tissue.
2 Botany Any of a number of rod-like structures in plants, e.g. a strand of sterile tissue dividing the cavity in a sporangium.
Oraciones de ejemplo
  • 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.
  • Special attention was paid to the structure and pattern of the distribution of septal trabeculae.
  • Locally there are ‘hints’ of a parallel fibrous, possibly spicular, structure in the normally irregularly crystalline microstructure of the trabeculae.

Origen

Mid 19th century: from Latin, diminutive of trabs 'beam, timber'.

  • 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.
  • 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.
