That gentleman ran out furiously, shears in hand, and with these instruments it seemed to be his intention to sever the epiglottis of Mr. Jinks, or at least his ears. But, as on a former occasion, when Mr.
B. Vertical section through larynx, showing inside. 1. Thyroid cartilage. 2. Cricoid cartilage. 3. Trachea. 4. Hyoid bone. 5. Epiglottis. 6. Vocal cord. 7. False vocal cord. 8. Lining of mucous membrane. The thyroid cartilage consists of two V-shaped pieces, one on either side of the larynx, meeting at their points in front, and each terminating at the back in an upward and a downward projection.
The razor had passed through the glosso-epiglottidean fold, a tip of the epiglottis, and through the pharynx down to the spinal column. There was little hemorrhage, but the man could neither swallow nor speak. The wound was sutured, tracheotomy done, and the head kept fixed on the chest by a copper splint.
As the food passes from the mouth, the pharynx is drawn up to receive it. At the same time the soft palate is pushed upward and backward, closing the opening into the upper pharynx, while the epiglottis is made to close the opening into the larynx. By this means all communication between the food canal and the air passages is temporarily closed.
Besides, when he considered for what end every part of the body was made, and what use Nature designed in their contrivance, it was easy to perceive that the epiglottis was framed on purpose that when we drink the windpipe should be shut, and nothing be suffered to fall upon the lungs.
She watched him sometimes, at the table, when on Sundays he ate the mid-day meal with them; his thin hatchet face, his prominent epiglottis. He wore a fresh cotton shirt then, with a flaming necktie, but he did not clean his fingernails. And his talk was always of tearing down, never of building up. "Just give us time, and we'll show them," he often said. And "them" was always the men higher up.
Of the epiglottis, a flexible cartilage, it is necessary to say little, as its function in voice-production, if it have any, has never been determined. It hangs as a flexible protective lid over the glottis, and food in being swallowed passes over and about it.
Every mouthful of our food slides right across the opening of the windpipe, which has to be protected by a special flap, or trap-door of gristle, called the epiglottis. If you try to eat and talk at the same time, the epiglottis doesn't get warning of the coming of a swallow of food in time to cover the opening of the windpipe, and the food goes down the wrong way and you cough and choke.
One anatomical fact may be so invincible that a view of the glottis cannot be obtained at all: the epiglottis may so overhang the opening to the larynx that a good view of its interior is absolutely impossible, in other cases only occasionally and under very favorable circumstances.
