Trabecular

Trabecular refers to a network of rod-shaped tissue structures found in various parts of the body, including the bone, spleen, and lymph nodes. The term is derived from the Latin word "trabecula", which means "small beam".

Anatomy

In the context of anatomy, trabecular tissue is found in various parts of the body. It forms a mesh-like structure that provides support and protection to the organs and tissues.

Trabecular Bone

Trabecular bone, also known as cancellous or spongy bone, is one of the two types of bone tissue found in the body. It is characterized by a honeycomb-like structure composed of numerous tiny plates called trabeculae. These plates provide structural support and are filled with red bone marrow, which is responsible for the production of blood cells.

Trabecular Meshwork

The trabecular meshwork is a part of the eye located near the base of the cornea. It is responsible for draining the aqueous humor – the clear fluid filling the front of the eye – from the eye into the bloodstream. Dysfunction of the trabecular meshwork can lead to increased eye pressure and is a risk factor for glaucoma.

Clinical Significance

Changes in the structure and function of trabecular tissue can lead to various health conditions. For instance, loss of trabecular bone mass is a characteristic feature of osteoporosis, a condition that leads to increased risk of bone fractures. Similarly, dysfunction of the trabecular meshwork can lead to glaucoma, a leading cause of blindness.
