Trabecular bone
Trabecular Bone
Trabecular bone (pronunciation: trəˈbɛkjʊlər boʊn), also known as cancellous bone or spongy bone, is one of the two types of bone tissue found in the human body.
Etymology
The term "trabecular" is derived from the Latin word "trabecula", which means "small beam". This is a reference to the beam-like or lattice structure of this type of bone tissue.
Description
Trabecular bone is characterized by its porous, honeycomb-like structure. It is found at the ends of long bones, in the pelvic bones, ribs, skull, and in the vertebrae of the spinal column. This type of bone is less dense than cortical bone, the other type of bone tissue, but it has a higher surface area and is more metabolically active.
Function
The primary function of trabecular bone is to support and protect the red and yellow bone marrow. It also plays a crucial role in calcium and phosphate metabolism.
