. Quain's elements of anatomy . Bodieswhich are to all appearance similarto the taste-buds presently to be described in the mucous membrane of the tongue are found imbedded inthis stratified epithelium. The lining membrane of the larynx is provided with numerous glands,which secrete an abundant mucus ; and the orifices of which may beseen almost everywhere, excepting upon and near the true vocal abound particularly upon the epiglottis, in the substance of whichare found upwards of fifty small compound glands, some of them per-forating the cartilage. Between the anterior surface of the epiglottis,the hyoid bone and the root of the tongue, is a mass of yellowish fat,erroneously named the epiglottic gland, in or upon which some smallglands may exist. Another collection of glands is placed within the foldof mucous membrane in fiont of each arytenoid cartilage, fiom whicha series may be traced forwards, along the corresponding superior vocalcord. The glands of the laryngeal pouches have already been 533 THE LAETNX Vessels and Nerves of the Larynx.—The arteries of the laiynx are derivedfrom the sui>erior thji-oid. a branch of the external carotid, and from the inferiorthyroid, a branch of the subclavian. The veins join the snperior, middle, andinferior thyroid veins. The lymvliatics are numerous, and pass through thecervical glands. Their mode of distribution resembles that in the trachea. Thenerves are supplied from the superior laryngeal and inferior or recurrentlaryngeal branches of the pneumogastric nerves, joined by branches of thesympathetic. The superior laryngeal nerves supply the mucous membrane, andthe crico-thyx-oid muscles, and also in part the arytenoid muscle. The inferiorlaiyngeal nerves supply, in part, the aryteaoid muscle, and all the other muscles,excepting the crico-thyroid. The superior and inferior laryngeal nerves of each side communicate with eachother in two places, viz., at the back of the larynx, beneath the pharyngealm
