prootic pro·o·tic (prō-ō'tĭk, -ŏt'ĭk)
Occurring or located in front of the ear.
The prootic is an irregular bone below the ear region and lying in advance of the opisthotic.
There are several foramina on the lateral surface of the prootic.
The squamosal is attached dorsoventrally to the posterior part of the parietal and to the lateral part of the prootic.
The alisphenoid is a small bone in the roof of the mouth before the prootic.
In Reptiles, the prootic and opisthotic frequently remain distinct even in the adult.
At this place of attachment there is on the prootic a relatively heavy crest that forms a rather broad articulating base.
It descends toward the parasphenoid and is attached to the prootic.
Parietal bones separated by the supra-occipital; prootic and exoccipital separated by the enlarged opisthotic.
The periotic capsule is ossified by a prootic centre, which meets the exoccipital behind.
These are the prootic, the epiotic and opisthotic, the situations of which have already been defined.
