This bone appears to represent both the coracoid and the clavicle, being formed partly of cartilage bone, partly of membrane bone.
The lower jaw or mandible remains partly cartilaginous, while its ossifications include two membrane bones and one cartilage bone.
It remains to a considerable extent cartilaginous, but is partly converted into cartilage bone, partly sheathed in membrane bone.
Each ramus of the mandible always consists of a cartilage bone, the articular, and several membrane bones.
The cartilage bone is the mento-meckelian (fig. 26, A, 14), a very small ossification at the extreme anterior end.
Each ramus is composed of five bones fused together, one being a cartilage bone, and the other four membrane bones.
cartilage bone n.
A bone that develops in the region of a cartilage after the cartilage is partially or completely destroyed. Also called endochondral bone.
