The vermiform appendix in man is termed rudimentary, being but a remnant of the much longer and more complex appendix of the same nature in living animals today. Embryonic Development.
In the alimentary apparatus there are the thymus-gland and the thyroid gland, the seat of goitre and the relic of a ciliated groove that the Tunicates and Acrania still have in the gill-pannier; there is also the vermiform appendix to the caecum.
It is quite large, as compared with the other intestines, in the human embryo, but ceases to grow after a certain stage of development. The cæcum is extremely long in some of the lower vegetable-eating animals, and the vermiform appendix seems to be a rudiment of the formerly extended portion of this organ.
Catalogitis is a stoppage of this fourth layer, whereby the functions of the fanlike structure are suffered no longer to cool the brain, and whereby also continuity of thought is interrupted, just as continuity of digestion is prevented by stoppage of the vermiform appendix. "The learned Professor Biersteintrinken," continued Dr.
All the loose blocks of coral on Keeling atoll were burrowed by vermiform animals; and as every cavity, no doubt, ultimately becomes filled with spathose limestone, slabs of the rock taken from a considerable depth, would, if polished, probably exhibit the excavations of such burrowing animals.
The vermiform appendage in which some recent medical writers have vainly endeavoured to find a utility is the shrunken remainder of a large and normal intestine of a remote ancestor. This interpretation of it would stand even if it were found to have a certain use in the human body. Vestigial organs are sometimes pressed into a secondary use when their original function has been lost.
"By the bye," interrupted Ellis, "could you tell me, for I never could find it in Herbert Spencer, what exactly in society corresponds to the spleen?" "Or the liver?" added Leslie. "Or the vermiform appendix?" Ellis pursued. "Oh, well," said Wilson, a little huffed at last, "if you are tired of being serious it's no use for me to continue." "I'm sorry, Wilson!" said Ellis.
Pressure deep enough to recognize distinctly the posterior abdominal wall, the pelvic brim and the structures lying between them and the examining finger forms the whole secret of success in the practice of palpation of the vermiform appendix." Can there be any wonder that this disease is so fulminating in the hands of the average medical man or can there be any surprise at the death rate?
And our moral powers are always enfeebled, and often diseased, from lack of strong exercise. And some blind guides, seeing only the disease, cry out for the extirpation of the whole faculty, as some physicians are said to propose the removal of the vermiform appendage in children. Similarly might the drunkard argue against the value of brain, because it aches after a debauch.
The plica semilunaris as a vestige of the nictitating membrane of certain birds. The pointed ear, or the turned-down tip of the ears of many men. The atrophied muscles, such as those that move the ear, that are well developed in certain people, or that shift the scalp, resembling the action of a horse in ridding itself of flies. The supracondyloid foremen of the humerus. The vermiform appendix.
