Squamosal Sentence Examples

In many owls the right and left ears are asymmetrical, and this asymmetry affects the whole of the temporal region, all the bones which surround the outer and middle ear, notably the squamosal and the quadrate, so that the skull becomes lopsided, one ear being turned obliquely down, the other upwards.

The quadrate is indirectly articulated with the skull, first by the horizontal, movable squamosal, secondly by the columella auris.

No ectopterygoid pterygoid not extending to quadrate; no supratemporal or squamosal; prefrontal forming a suture with nasal; coronoid present; vestiges of pelvis present.

The quadrate is carried by the horizontally-elongated squamosal, which rests loosely upon the skull.

The quadrate is short and thick, and is carried by the broad and short squamosal, which lies flat against the skull, reminding in this respect of Ilysia.

The under jaws are hinged on to the quadrate bones, which extend obliquely backwards, and are immovably wedged in between the squamosal and the lateral occipital wings.

The latter sends a horizontal or slightly ascending process backwards below the orbit to join the under surface of the zygomatic process of the squamosal, which is remarkably large, and instead of ending as usual behind the orbit, runs forwards to join the greatly developed post-orbital process of the frontal, and even forms part of the posterior and inferior boundary of the orbit, an arrangement not met with in other mammals.

The squamosal enters considerably into the formation of the temporal fossa, and, besides sending the zygomatic process forwards, it sends down behind the meatus auditorius a post-tympanic process which aids to hold in place the otherwise loose tympano-periotic bone.

The periotic and tympanic are welded together, but not with the squamosal.

The former has a wide but shallow floccular fossa on its inner side, and sends backwards a considerable " pars mastoidea," which appears on the outer surface of the skull between the posttympanic process of the squamosal and the exoccipital.

The squamosal bone is large and either in contact with the frontals and parietals or separated from them by a vacuity; the orbit is sometimes roofed over by bone.

Here the temporal fossa is bridged over by the junction of the post-frontal and squamosal processes (pf., sq.).
