"Occipital" Quotes from Famous Books
 ... PARIETAL AND OCCIPITAL LOBES (LATERAL SURFACE).—The Postcentral Fissural Complex—In this hemicerebrum, the postcentral and subcentral are combined to form a continuous fissure, attaining a length of 8.5 cm. Dorsally, the fissure bifurcates, embracing the gyre indented by the caudal limb of ...

... state of nature, does cutting off the sap tend to produce flower-buds? I know it does in trees in orchards. Owen has been doing some grand work in the morphology of the vertebrata: your arm and hand are parts of your head, or rather the processes (i.e. modified ribs) of the occipital vertebra! He gave me a grand lecture on a cod's head. By the way, would it not strike you as monstrous, if in speaking of the minute and lessening jaws, palpi, etc., of an insect or crustacean, any one were to say they were produced by the affaiblissement of the less important ...

... proportion than in either the chimpanzee or the gorilla. "On comparing the brain of man with the brains of the orang, chimpanzee, and baboon, we find a successive decrease in the frontal lobe, and a successive and very great increase in the relative size of the occipital lobe. Concomitantly with this increase and decrease, certain folds of brain substance, called 'bridging convolutions,' which in man are conspicuously interposed between the parietal and occipital lobes, seem as utterly to disappear in the chimpanzee, as they do in the baboon. ...

... process of the nasal does not meet the frontal process of the maxilla. A large frontoparietal fontanelle is evident between the frontoparietals. The tegmen tympani are much reduced and maintain only cartilaginous contact with the posterior arms of the squamosals. The foramen magnum, occipital condyles, and exoccipitals show no unusual features. The pars facialis and frontal process of the maxilla are greatly reduced. The maxilla and premaxilla are articulated. The high, narrow alary processes of the premaxillae extend dorsally about two-thirds of the ...

... "in each type some of these bones acquire special arrangements and very different magnitudes."[160] And no investigator of homologies doubts that a considerable number of the bones which form the skull of any osseous fish are distinctly homologous with the cranial bones of man. The occipital, the parietal, and frontal, the bones which surround the internal ear, the vomer, the premaxilla, and the quadrate bones, may be given as examples. Now, if such close relations of homology can be brought about independently ...

... his species; and it is to his lower extremities alone that we must look for distinguishing features. As our researches extend downwards from head to foot, the first thing that strikes us is a protuberance of the ante-occipital membranes, so great as to present a back view that describes two sides of a scalene triangle, the apex of which projects posteriorly nearly half way down the figure. That a due equilibrium may be preserved in this difficult position (technically called "the first"), ...

... of the resonance of the head cavities is perceived chiefly by those who are unaccustomed to using the head tones. The resonance against the occipital walls of the head cavities when the head tones are employed, at first causes a very marked irritation of the nerves of the head and ear. But this disappears as soon as the singer gets accustomed to it. The ...

... lesion of one focus in the pia mater of the right side suggested an encephalitis more marked on the right side. Microscopically a few small vessels showed plugs of polynuclear leucocytes. The nerve cells were affected by various acute changes. The visuo-psychic portion of an occipital section (right) showed suprastellate cell-losses ...

... end of the nose. This process is seemingly a cruel one, though I doubt whether it causes much pain, as it is done in earliest infancy, while the bones are soft and cartilaginous, and easily pressed into this distorted shape by forcing the occipital up and the frontal down, so that the skull at the top in profile will show a breadth of not more than an inch and a half or two inches, when in a front view it exhibits a great expansion on the sides, making it at the top nearly the width of one and a half natural heads. ...

... more frequent persistence of the metopic or frontal suture. The effacement, more or less complete, of the parietal or parieto-occipital sutures in a large number of criminals. The notched sutures are the most simple. The frequency of the wormian bones in the region of the median and in the lateral posterior frontal. The backward direction of the plane of the occipital depression. ...

... entered at the juncture of the nasal and frontal bones," explained Harley, rapidly, "and it came out between the base of the occipital and first cervical. Without going into unpleasant surgical details, the wound was a perfectly straight one. There ...
