Intramembranous

Within the mesenchymal membrane, cells cluster together and begin secreting osteoid (unmineralized bone matrix). These clusters are called , from which bone spicules radiate outward.

Intramembranous ossification is the reason human birth is possible. Because the bones of the skull form via this membrane method, they don't have to be fully hardened when a baby is born. They remain as flexible "fontanelles" (soft spots). This allows the baby's head to compress slightly during delivery and then expand as the brain grows, eventually hardening into a protective helmet of bone. This process begins between the sixth and seventh weeks of e

Put them together, and you get "occurring within a membrane." In the context of biology, this usually refers to .
