The frontoparietals are represented by two slender ossifications dorsomedial to the orbits; the septomaxillaries are present as small ossifications anterior to the nasal capsules (Pl.
After the maxillaries and premaxillaries develop, the vomers appear as small horizontal ossificationsanterior to the parasphenoid.
The Order of Occurrence of Cranial Ossifications in the Skull of Smilisca baudini.
The orbit has a cartilaginous sclerotic in which are two small ossifications (fig.
There is a large parasphenoid, but there are no ossifications in the basisphenoidal, presphenoidal, and alisphenoidal regions.
Owing to this development of dermal bone, the original cartilaginous arch becomes much reduced, butossifications representing the scapula and coracoid occur in bony Ganoids and Teleosteans.
A number of large ossifications take place in the cartilage of the auditory capsules.
Although it is mainly cartilaginous a number of ossifications take place in the skull, and membrane bones are now found definitely developed, especially in connection with the roof of the cranium.
Lateral ethmoids are developed, and there are ossifications in the sphenoidal region which vary in different forms.
Two pairs of large ossifications take place in the cranial walls.
The lower jaw or mandible remains partly cartilaginous, while its ossifications include two membrane bones and one cartilage bone.
There is a ring of ossifications in the sclerotic.
The carapace consists of a number of polygonal ossifications fitting closely together and altogether distinct from the vertebrae and ribs.
The suspensorium in bony Ganoids, as in the Chondrostei, is hyostylic, and there are two ossifications in the hyomandibular cartilage, viz.
Embryological evidence tends the same way, inasmuch as dermal ossifications appear much earlier in the developing animal than do the ossifications in the endoskeleton.
In the pelvic girdle as in the pectoral one dorsal, and (commonly) two ventral ossifications take place.
Similar localised ossificationsare met with in Charcot's disease of joints, and in fractures which have repaired with exuberant callus.
In Teleostei and bony Ganoids, a considerably greater number of ossificationsoccur in the cartilage.
Membrane bones and ossificationsof the cranium, pp.
In the Dipnoi this occurs to the smallest extent, the only ossifications occurring in the lateral parts of the occipital region, and forming the exoccipitals.
In the Amphibia the ossifications in the cartilage are comparatively few.
In Mammals the three ossifications fuse into a continuous whole--the periotic bone--which may be partially united with the adjacent parts.
The regions which may be distinguished owing to the growth of these processes have received names from ossifications in them which are found in other types.
The ossificationsin the tissue surrounding the sheath usually (fig.
Kölliker's distinction, therefore, was between the bones formed in the primordial cartilaginous cranium on the one hand, and the superficial ossifications in fibrous tissue on the other hand.
Ethmoidal ossifications were not preserved in any of the specimens studied.
The lateral processes have larger ossifications and the base of the stalk is more robust in M.
Length of lateral digital ossificationsmore than 1/3 breadth of stalk 2 1'.
Usually, three digitate processes of cartilaginous material in which additional ossifications may occur arise from the terminus of the shaft.
The proportions and curvature of the stalk vary as do the proportions of the terminal ossifications to each other and to the stalk.
American species of Microtus (genus and subgenus) in which the lateral ossifications are weakly developed or absent (although cartilaginous lateral processes are present) include M.
The proportions of the four ossificationsare approximately the same.
The secondary and tertiary ossificationsare progressively more common in older voles.
In other subgenera, species of Microtus having reduced lateral ossifications are M.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "ossifications" in a variety of sentences. We hope that you will now be able to make sentences using this word.
