In early childhood, the bones of the head are separate to allow the brain to expand; but as we grow older they gradually unite, the better to protect the delicate brain tissue. The Cranium. The cranium is a dome-like structure, made up in the adult of 8 distinct bones firmly locked together. These bones are: One Frontal, Two Parietal, Two Temporal One Occipital, One Sphenoid, One Ethmoid.
Gastric disturbances are quite common, severe vomiting being produced by minimum doses; not infrequently, intense mental confusion, vertigo, and headache, lasting hours and even days, sometimes referable to the frontal region and sometimes to the occipital, are seen in certain nervous individuals after a dose of from 1/4 to 5/6 gr. of opium.
The occipital protuberance occupies the extreme posterior end of the skull, when the glabello-occipital line is made horizontal, and so far from any part of the occipital region extending beyond it, this region of the skull slopes obliquely upward and forward, so that the lambdoidal suture is situated well upon the upper surface of the cranium. Drawings from Dr.
Pieces of bone at the superior angle of the occipital bone were removed, leaving the aura exposed for a space one by four inches. The man was unconscious for four days, but entirely recovered in eighteen days, with only a slightly subnormal hearing as an after-effect of his fall.
Wilson speaks of a child who fell on an upright copper paper-file, which penetrated the right side of the occipital bone, below the external orifice of the ear, and entered the brain for more than three inches; and yet the child made a speedy recovery.
HEAD Should be quite characteristic of this grand sporting dog, as that of the Bloodhound or the Bulldog; its very stamp and countenance should at once convey the conviction of high breeding, character and nobility; skull well developed, with a distinctly elevated occipital tuberosity, which, above all, gives the character alluded to; not too wide across muzzle, long and lean, never snipy nor squarely cut, and in profile curving gradually from nose to throat; lean beneath eyes, a thickness here gives coarseness to the whole head.
Professor Schaaffhausen, who, with the other experienced zoologists, did not share these doubts, observed that the cranium, which included the frontal bone, both parietals, part of the squamous, and the upper third of the occipital, was of unusual size and thickness, the forehead narrow and very low, and the projection of the supra-orbital ridges enormously great.
The forehead is narrow and low, though the middle and hinder portions of the cranial arch are well developed. Unfortunately, the fragment of the skull that has been preserved consists only of the portion situated above the roof of the orbits and the superior occipital ridges, which are greatly developed, and almost conjoined so as to form a horizontal eminence.
The coronal suture. c. The apex of the lamboidal suture. d. "In human skulls, the superior curved ridge of the occipital bone and the occipital protuberance correspond, approximatively, with the level of the tentorium and with the lateral sinuses, and consequently with the inferior limit of the posterior lobes of the brain.
Impressible subjects may be selected by the development of the organs of Impressibility, and the general predominance of the frontal and coronal regions of the brain over the occipital.
