    nication between each other, which form a small plexus beneath the complexus muscle. All the branches of the posterior cervi- cal plexus are distributed to the muscles on the back part of the neck, with the exception of a large ascending branch of the se- cond cervical nerve, the occipitalis major. This nerve pierces the complexus, and ascends with the occipital artery, to be dis- tributed to the integument on the posterior part of the head. It supplies no muscles. Organ of Voice. The Larynx is situated at the forepart of the neck between the trachea and the base of the tongue. It is composed of car- tilages, ligaments, muscles, vessels, and nerves, and mucous membrane. The Cartilages are, the Thyroid, Two Arytenoid, Cricoid, Epiglottis. The Thyroid (Svpeog—et$o$, like a shield) is the largest carti- lage of the larynx: it consists of two lateral portions or alse, which meet at an acute angle in front, and form the projection which is known by the name of pomum Adami. Where the pomum Adami is prominent, a bursa mucosa is often found be- tween it and the skin. Each ala is quadrilateral, and forms a rounded border poste- riorly, which terminates above, in the superior cornu, and below, in the inferior cornu. Upon the side of the ala is an oblique line, into which the sterno-thyroid muscle is inserted, and from which the thyro- hyoid takes its origin. Behind this is a vertical line which gives origin to the inferior constrictor muscle. In the receding angle formed by the meeting of the two alee upon the inner side of the cartilage, and near to its lower border, are attached the epiglottis, the chordae vocales, the thyro-aryte- noid, and thyro-epiglottidean muscles. The Cricoid (y.piKoc,—ethq, like a ring) is a ring of cartilage, narrow in front and broad behind, where it is surmounted by two rounded surfaces, which articulate with the arytenoid car- tilages. Upon the middle line, posteriorly, is a vertical ridge which gives attachment to the oesophagus. On each side of the ridge are the depressions which lodge the crico-arytenoidei postici muscles. On either side of the ring is a glenoid cavity, which articulates with the inferior cornu of the thyroid carti- lage.
