The paralysis begins at the point in the vertebral column where the injury was received. But it tends to spread upward. If it gets as far as certain nerves upon which the movements of the diaphragm depend, then you die. I wonder whether that will be my case?" Mrs.
Touch it and feel how solid it is, and how few dangers there can be for anything placed behind it. Well, that is the rampart which has been given to the Aorta. As this descends, it slips behind the heart and takes up its place in front of the vertebral column which it follows all the way down the back, just to the top of the loins.
"May I ask to whom I have the honour of speaking?" asked the Professor, in his coldly polite manner his most superior professional attitude. "My name is Andrew McKnight, if that's any good to you. If that is a gorilla, sir, where are his vertebral processes, tell me that? And how comes it that his legs are almost as long as those of man?"
Several other features of man's embryonic development the budding of the hind limbs high up, instead of at the base of, the vertebral column, the development of the ears, the nose, the jaws, etc. have the same lesson, but the one detailed illustration will suffice. We have been quite unable to follow the vast changes which have meantime taken place in its organisation.
In this way the contiguous vertebrae of the various sections of the column may take each other's places. In order to understand the embryology of the human vertebral column we must first carefully consider the shape and connection of the vertebrae.
I find that the vertebral column of a full-grown Gorilla, in the Museum of the Royal College of Surgeons, measures 27 inches along its anterior curvature, from the upper edge of the atlas, or first vertebra of the neck, to the lower extremity of the sacrum; that the arm, without the hand, is 31-1/2 inches long; that the leg, without the foot, is 26-1/2 inches long; that the hand is 9-3/4 inches long; the foot 11-1/4 inches long.
Considering the cranium, according to what he conceives to be the true anatomical theory, as simply a prolongation of the vertebral column, the primitive centre of the whole nervous system, he argues that the functions, intellectual and emotional, which are proper to the upper and anterior parts of it, are less energetic than the animal propensities, whose organs lie in the lower and posterior region, just in proportion as they are further removed from the spine; and that, for this reason, the latter must first come into action, then the intermediate organs of sentiment, and, last of all, the intellectual powers.
Externally it differs little from the ordinary lizard; but in many important points of internal structure, especially in the primitive construction of the vertebral column, the skull, and the limbs, it occupies a much lower position, and approaches its amphibian ancestors, the Stegocephala.
In about five weeks after the removal of the bullet nearly the entire body of the 3d cervical vertebra, including the anterior half of the transverse process and vertebral foremen, was spontaneously discharged. Nearly eight years afterward Keen saw the man still living, but with his right shoulder and arm diminished in size and partly paralyzed.
Past the type racks and cases, which occupied the first half of this apartment, were grouped benches, stools, packing-cases, and a few maimed and deformed chairs for the accommodation of the assembly. Then came a hand printing-press, on which were spread the remains of some comrade's repast: the vertebral column of a bloater and an empty condensed-milk can, among other relics.
