Verified step by step guidance

Understand the process of intramembranous ossification, which is one of the two methods of bone formation. It primarily occurs in the flat bones of the skull, mandible, and clavicles.

Recognize that intramembranous ossification does not involve a cartilage precursor, unlike endochondral ossification, which starts with a hyaline cartilage model.

Identify that during intramembranous ossification, bone develops directly from mesenchymal tissue, which is a type of fibrous connective tissue.

Note that mesenchymal cells differentiate into osteoblasts, which are the cells responsible for bone formation. These osteoblasts begin to secrete bone matrix, leading to the development of bone.

Understand that as the bone matrix accumulates, it forms trabeculae, which are the small, supporting beams of bone tissue. Eventually, these trabeculae fuse to form the flat bones.
