| lymphatic stroma | The network of reticular fibres and associated reticular cells of lymphatic tissue. (05 Mar 2000) |
|---|---|
| lymphatic system | <anatomy> The tissues and organs (including the bone marrow, spleen, thymus and lymph nodes) that produce and store cells that fight infection and the network of vessels that carry lymph. (12 May 1997) |
| lymphatic tissue | A structure found within the lymphatic system that consists of lymphocytes within a network of fibres. (09 Oct 1997) |
| lymphatic valvule | One of the delicate semilunar valves found in lymphatic vessels; they are usually paired and similar in structure to venous valves and occur at close intervals along the vessel wall. Synonym: valvula lymphatica. (05 Mar 2000) |
| lymphatic vessel | <anatomy> Vessels that remove cellular waste from the body by filtering through lymph nodes and eventually emptying into the blood system. They are similar to blood vessels but transport lymph fluid. (14 Oct 1997) |
| lymphatic vessels | The vessels that convey the lymph; they anastomose freely with each other. Synonym: vasa lymphatica, absorbent vessels, lymphatic vessels, lymphatics. (05 Mar 2000) |
| lymphatic vessel tumours | Neoplasms composed of lymphoid tissue, a lattice work of reticular tissue the interspaces of which contain lymphocytes. The concept does not refer to neoplasms located in lymphatic vessels. (12 Dec 1998) |
| papillomatosis, laryngeal | Warty growths on the vocal cords. most common in young children. Recurrences are, unfortunately, frequent. Remission may occur after several years. Papillomatosis of the larynx can be due to the baby contracting human papilloma virus (HPV) during birth through the vaginal canal from a mother with genital warts (which are due to HPV). Each year, about 300 infants are born with the virus on their vocal cords because of maternal transmission. (12 Dec 1998) |
| recurrent laryngeal nerve | <anatomy, nerve> A branch of a nerve (the vagus nerve) that comes down the neck and turns back ( recurs ) to supply the larynx (the voice box ). (12 Dec 1998) |
| granuloma, laryngeal | A polypoid granulomatous projection into the lumen of the larynx. (12 Dec 1998) |
| protective laryngeal reflex | Closure of the glottis to prevent entry of foreign substances into the respiratory tract. (05 Mar 2000) |
| subcutaneous bursa of the laryngeal prominence | The bursa located between the junction of the laminae of the thyroid cartilage and the skin. Synonym: bursa subcutanea prominentiae laryngeae, laryngeal bursa. (05 Mar 2000) |
| superior laryngeal artery | <anatomy, artery> Origin, superior thyroid; distribution, muscles and mucous membrane of larynx; anastomoses, cricothyroid branch of superior thyroid and terminal branches of inferior laryngeal. Synonym: arteria laryngea superior. (05 Mar 2000) |
| superior laryngeal cavity | The upper part of the laryngeal cavity from the superior aperture to the vestibular folds, bounded anteriorly by the epiglottis, laterally by themucosa overlying the quadrangular membranes and posteriorly by the mucosa overlying the arytenoid cartilages and arytenoideus muscle. Synonym: vestibulum laryngis, atrium glottidis, superior laryngeal cavity. (05 Mar 2000) |
| superior laryngeal nerve | <anatomy, nerve> A branch of the vagus nerve at the inferior ganglion; at the thyroid cartilage it divides into two branches; the internal laryngeal nerve, a sensory branch which supplies the mucous membrane of the larynx superior to the vocal folds, and the external laryngeal nerve, a motor branch which supplies the inferior pharyngeal constrictor and the cricothyroid muscle. Synonym: nervus laryngeus superior. (05 Mar 2000) |
