Bone ossification is not the same as bone calcification process. 1. Endochondral Ossification Steps . Osteogenesis, more commonly referred to as ossification, is a process by which new layers of bone tissues are laid by osteoblasts. Intramembranous ossification describes the process of ossification from mesenchymal cells (stem cells) without a cartilaginous template and is involved in the healing process of fractures. 2. a. In this process, the mesenchyme first differentiates in to osteoblasts (bone–forming cell) which then begins to deposits osteoid (unmineralized matrix). Furthermore, endochondral ossification is involved in the formation of long bones while intramembranous ossification … Intramembranous and endochondral ossification+ 31. Blood vessels invade the perichondrium, mesenchymal cells become osteoblasts, the perichondrium is converted into a periosteum and the inner layer produces bone. growth occurs by cell division of chondrocytes.

During intramembranous ossification, compact and spongy bone develops directly from sheets of embryonic, mesenchymal (undifferentiated) connective tissue.The flat bones of the face, most of the cranial bones, and the clavicles (collarbones) are formed via intramembranous ossification. bone breakdown by osteoclasts forms the medullary cavity.

T/F Flat bones have a marrow cavity in the diaphysis. Later, some connective tissue cells become osteoblasts and deposit spongy bone within the membranes starting in the centre of the future bone. Intramembranous ossification: Is the process of bone formation in which the mesenchyme differentiated directly into the bone, example, is the flat bones of the skull. By the sixth or seventh week of embryonic life, the actual process of bone development, ossification (osteogenesis), begins. Primary and secondary ossification.
