The supraoccipital also has a medial crest that extends a short distance posteriorly from the supratemporal crest onto the exoccipitals at their dorsal line of fusion.
The exoccipitals bear moderate occipital crests that extend posterolaterally across the supraoccipital as branches from the supratemporal crest.
From anteriormost projection of nasal bones to posteriormost projection of supraoccipital bone.
When ossification sets in, the ear-capsule forms three bones, of which two fuse with the supraoccipital and exoccipitals.
So, too, the supraoccipital in man cannot be fully homologised with the supraoccipital of many mammals, for its upper half arises at first in isolation as a secondary bone (p.
The supraoccipital is formed in cartilage above the exoccipitals.
The supraoccipital is an accessory bone developed in relation to bigger brains.
Soemmering is the special homologue of the supraoccipital bone of the cod, although it is developed out of pre-existing cartilage in the fish and out of aponeurotic membrane in the human subject.
In front there is the prootic, which often meets the exoccipital behind; behind there is above and in close connection with the supraoccipital the epiotic, and below in close connection with the exoccipital the opisthotic.
In the occipital region there is a lateral ossification on each side of the exoccipital, the basioccipital region being unossified, and the supraoccipitalat the utmost indurated by a calcareous deposit.
In the region of the occipital cartilaginous ring there appears a basioccipital and supraoccipital and two exoccipitals.
Then the supraoccipital never has a very strongly developed median prominence, and the temporal fossae are comparatively short.
The teeth are minute or absent and there is a highsupraoccipital crest.
The young are marked by black cross-bands which disappear with age, and in the adult the supraoccipital crest is greatly thickened and the skull otherwise modified.
The ventral surface of the supraoccipital spine, which is widest proximally in muticus, is always narrow proximally in ferox and spinifer.
Additional evidence, however, is against this possibility; the notch in the supraoccipital is deeper in specimens (No.
The difficulty results from the holotype having a barely detectable emargination in the posterior border of the supraoccipital shield.
The outline of the supraoccipitalis straight and nearly vertical.
On account of these defects and the immaturity of the individual the forward inclination of the supraoccipital is much greater than in the skull shown in fig.
The shape of the superior margin of the supraoccipital is alike in both.
The supraoccipital rises vertically above each condyle to the very top of the skull, being neither convex nor strongly bent forward as in other species, and especially bidens.
The only species which approaches stejnegeri in this respect is hectori, but in the latter the supraoccipital instead of being flat above the condyles is very strongly convex.
The supraoccipital has a distinct median ridge, with a longitudinal depression on each side, bounded externally by a prominent convexity.
Skull: Longer and narrower; nasals and rostrum longer; extension of supraoccipital posterior to lambdoidal suture markedly less; tympanic bullae markedly smaller; upper incisors longer and not as strongly recurved.
The crest diverges around the foramen, reunites immediately behind it, and continues posteriorly to its junction with the supraoccipital crest (Estes, 1961).
The medial division or temporal arose from the sagittal crest and supraoccipital crest and the intervening dermal roof.
In Didelphis the sagittal crest is high and dorsally convex in lateral aspect, arising posterior to and medial to the orbits, reaching its greatest height near the midpoint, and sloping down to its termination at the supraoccipital crest.
The supraoccipital crest flares upward to a considerable extent in Thrinaxodon and slopes posteriorly from the skull-roof proper.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "supraoccipital" in a variety of sentences. We hope that you will now be able to make sentences using this word.
