trabecula

The primary anatomical and functional unit of cancellous bone is the trabecula.

They can be composed of other materials; in the heart, for example, muscles such as trabeculae carneae and septomarginal trabecula form similar structures.

In the 19th century, the neologism trabeculum (with an assumed plural of trabecula) became popular, but is less etymologically correct.

The septomarginal trabecula (also known as moderator band) is a muscular band of heart tissue found in the right ventricle.

Aspiration does not always represent all cells since some such as lymphoma stick to the trabecula, and would thus be missed by a simple aspiration.

Both patterns have basaloid cells arranged in solid nests, nodules or trabecula, with focal peripheral palisading.

Multiple perforations in a septum may reduce it to a collection of trabecula, as happens to the walls of some of the pulmonary alveoli in emphysema.

The fibers and cysts will be found among the trabecula of the Coronoid process, the ramus of mandible, the body of mandible and the maxilla regions.

This septomarginal trabecula is important because it carries part of the right bundle branch of the AV bundle of the conduction system of the heart to the anterior papillary muscle.

Then calcification of the matrix occurs and osteoprogenitor cells that entered the cavity via the periosteal bud, use the calcified matrix as a scaffold and begin to secrete osteoid, which forms the bone trabecula.

The white fluffy material is seen in many tissues both ocular and extraocular: in the anterior chamber structures, trabecular meshwork, central disc, zonular fibres, anterior hyaloid membrane, pupillary and anterior iris, trabecula, and occasionally the cornea.

A trabecula (plural trabeculae, from Latin for "small beam") is a small, often microscopic, tissue element in the form of a small beam, strut or rod, generally having a mechanical function, and usually composed of dense collagenous tissue (such as the trabecula of the spleen.)
