Seite 473 - ... in A, the anterior root divided; 6, the posterior roots, the fibres of which pass into the ganglion 6'; 7, the united or compound nerve; 7', the posterior primary branch, seen in A and D to be derived in part from the anterior and in part from the posterior root.
Seite 46 - If watched for a minute or two, an irregular projection is seen to be gradually thrust out from the main body and retracted; a second mass is then protruded in another direction, and gradually the whole protoplasmic substance is, as it were, drawn into it. The amoeba thus comes to occupy a new position, and when this is repeated several times we have locomotion in a definite direction, together with a continual change of form. These movements, when observed in other cells, such as the colorless blood-corpuscles...
Seite 635 - ... one side, to water, or the fluid of the labyrinth, on the other side, much better than solid media not so constructed. But the propagation of sound to the fluid is rendered much more perfect if the solid conductor thus occupying the opening, or fenestra ovalis, is by its other end fixed to the middle of a tense membrane, which has atmospheric air on both sides.
Seite 118 - These foramina are of course purely imaginary, but no one ventured to dispute their existence till Servetus boldly stated that he could not succeed in finding them. He further asserted that the blood passed from the Right to the Left side of the heart by way of the lungs, and also advanced the hypothesis that it is thus "revivified...
Seite 217 - The acts of expansion and contraction of the chest take up under ordinary circumstances a nearly equal time. The act of inspiring air, However, especially in women and children, is a little shorter than that of expelling it, and there is commonly a very slight pause between the end. of expiration and the beginning of the next inspiration. The respiratory rhythm may be thus expressed: — Inspiration Expiration C or 8 A very slight pause.
Seite 685 - ... granular substance lying external to the fibrous stroma; 4, blood-vessels; 5, ovigerms in their earliest stages occupying a part of the granular layer near the surface; 6, ovigerms which have begun to enlarge and to pass more deeply into the ovary; 7, ovigerms round which the...
Seite 641 - ... the cochlea we have to do with a series of apparatus adapted for performing sympathetic vibrations with wonderful exactness. We have here before us a musical instrument which is designed, not to create musical sounds, but to render them perceptible, and which is similar in construction to artificial musical instruments, but which far surpasses them in the delicacy as well as the simplicity of its execution. For, while in a piano every string must have a separate hammer by means of which it is...
Seite 532 - Together with these effects of paralysis of the facial nerve, the muscles of the face being all powerless, the countenance acquires on the paralyzed side a characteristic, vacant look, from the absence of all expression : the angle of the mouth is lower, and the paralyzed half of the mouth looks longer than that on the other side; the eye has an unmeaning stare.
Seite 668 - Even the image of our hand, while used in touch, is seen inverted. The position in which we see objects, we call, therefore, the erect position.
Seite 629 - ... its apex. They are found progressively to increase in length, and become more oblique ; in other words the tunnel becomes wider, but diminishes in height as we approach the apex of the cochlea. Leaning, as it were, against these external and internal pillars are certain other cells, of which the external ones terminate in small hair-like processes.
