Definition

A membrane bone (also called dermal bone) is a bone that forms directly from connective tissue membranes, rather than from cartilage. Most of the bones in your skull, like the parietal and frontal bones, are membrane bones. This type of bone formation is called intramembranous ossification. It's a direct process, skipping the cartilage stage. ðŸĶī

Etymology

"Membrane" refers to the thin sheet of tissue from which the bone develops. "Bone" refers to the hard tissue itself. Thus, "membrane bone" means bone formed from a membrane. It explains the bone's origin directly.
