Trabecula

Trabecula is a term used in various fields of biology to refer to various types of structures, but generally refers to any small, often microscopic, tissue element in the form of, or arranged like, a small beam, strut or rod.

Anatomy

In anatomy, trabeculae are often bundles or beams of connective tissue, such as in the spleen. They can also refer to a small, calcified, spicule in spongy bone that forms a network, providing structural support and serving as a framework for the attachment of bone marrow tissue.

Cardiology

In cardiology, trabeculae carneae refers to the muscular ridges found on the inner walls of the ventricles of the heart. These ridges are thought to prevent suction that would occur with a flat surface, and increase the force of contraction without increasing the amount of contraction.

Ophthalmology

In ophthalmology, trabeculae refer to the mesh-like connective tissue in the eye that helps drain the aqueous humour.

Botany

In botany, trabeculae are plate-like strips of conductive tissue in mosses.
