What type of bone is primarily found at the ossification center?

The ossification center is primarily associated with the formation of woven bone, which is an immature form of bone that is typically laid down quickly during the early stages of bone development and healing. Woven bone is characterized by its haphazard organization of collagen fibers, making it less organized than mature bone types. This type of bone plays a crucial role during ossification, as it serves as a temporary structure upon which more organized and stronger bone forms later.

In the context of skeletal development, woven bone is usually replaced by lamellar bone, which includes both spongy and compact bone. The process of remodeling will typically see woven bone transformed into the more stable structures of spongy and compact bone as the organism matures. This transitional nature of woven bone is key to understanding how bones develop and heal following injury.

Compact bone, spongy bone, and cortical bone are more advanced and refined structures that will develop after the initial formation of woven bone, hence they do not represent the primary type found at the ossification center.
