(17) As the angle between the basisphenoid and the parietal bones stays more or less constant between 14 and 60 days, the impression is created that both the anterior and posterior parts of the neural skull rotate upwards relative to this bone complex.
(18) Skeletal malformations were seen in the bones of the craniocervical transition, with the occipital, basisphenoid, and atlas bones deficient or misshapen.
(19) Such a hangman's noose, when the knot is at the side of the head (subaural), produces fractures of the base of the skull tending to extend bitemporally through the basisphenoid.
(20) With minimal surgical invasion, we used either the opening of the craniopharyngeal duct to access the chiasmatic cistern or the suture between the basisphenoid and basioccipital bones to access the interpeduncular cistern.
Ossification
Definition:
(n.) The formation of bone; the process, in the growth of an animal, by which inorganic material (mainly lime salts) is deposited in cartilage or membrane, forming bony tissue; ostosis.
(n.) The state of being changed into a bony substance; also, a mass or point of ossified tissue.
Example Sentences:
(1) Radiologic abnormalities included an unusual "moth-eaten" appearance of the markedly short long bones, bizzare ectopic ossification centers, and marked platyspondyly with unusual ossification centers.
(2) Despite study for over 100 years, sites and patterns of laryngeal calcification and ossification are understood incompletely.
