Microscopic Structure of Bone Overview

Made up of trabeculae, it is found in flat, short, irregular, and sesamoid bones, and is located at the epiphyses of long bones, closely associated with red bone marrow.

A type of bone tissue that has very few spaces and coats the exterior of all bones; it makes up the majority of the diaphysis of long bones.

The flat plates of bone found in spongy bone that form the spaces where red bone marrow is located.
