What is the trabeculae of bone?

Trabecular bone is a highly porous (typically 75–95%) form of bone tissue that is organized into a network of interconnected rods and plates called trabeculae which surround pores that are filled with bone marrow.

What does trabecular mean in medical terms?

Trabecula: A partition which divides or partly divides a cavity. One of the strands of connective tissue projecting into an organ that constitutes part of the framework of the organ as, for example, the trabeculae of the spleen.

What are the trabeculae of compact bone?

Whereas compact bone tissue forms the outer layer of all bones, spongy bone or cancellous bone forms the inner layer of all bones. Spongy bone tissue does not contain osteons that constitute compact bone tissue. Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates.

How are trabeculae oriented?

Trabeculae oriented horizontally tend to be perforated, become thinner, or eventually disappear (Gibson, 2005; Homminga et al., 2004; Kothari et al., 1999; Thomsen et al., 2002), while those oriented longitudinally tend to retain their thickness (Homminga et al., 2004; Thomsen et al., 2002).

Which is the best description of a trabecular bone?

sub·stan·ti·a spon·gi·o·sa. (sŭb-stan’shē-ă spŭn-jē-ō’să) [TA] Bone in which the spicules or trabeculae form a three-dimensional latticework (cancellus), with the interstices filled with embryonal connective tissue or bone marrow. Synonym(s): cancellous bone, spongy bone (1) , spongy substance, trabecular bone.

Where is trabeculae found in long bone?

Trabeculae are the thin columns and plates of bone that create a spongy structure in a cancellous bone, which is located at the ends of long bones and in the pelvis, ribs, skull, and vertebrae.

What kind of cells are in A trabecula?

If you could shrink yourself even more and go inside a trabecula, you would find three types of cells that work together to keep your bones strong and healthy: the osteoblasts, osteocytes, and osteoclasts. Cells called osteoblasts are responsible for making bone tissue.

How does the trabeculae help the cancellous bone?

Although cancellous bone has a lot of holes in it, it is still very strong. Every time you walk or run or jump, you put large mechanical stresses on the bones in your hips, spine, and pelvis, and they don’t break. This strength is provided by the trabeculae.
