Sorry, no etymologies found.
For example, the endocranium is the membrane that lines the inside of the skull.
The elongated overall shape of the braincase has not changed much in the course of more than two million years of human evolution, despite a big increase in endocranium volume.
Tympanic bullae are large, robust, and firmly attached to the underside of the endocranium.
