| opioid partial agonist | <pharmacology> A compound that has an affinity for and stimulates physiologic activity at the same cell receptors as opioid agonists but that produces only a partial (i.e., submaximal) bodily response. (16 Dec 1997) |
| total or partial anomalous pulmonary venous connections | Connections in which some or all of the pulmonary veins connect to the right atrium or one of its tributaries. (05 Mar 2000) |
| epilepsy, complex partial | Epileptic seizures that are episodic changes in behaviour in which an individual loses conscious contact with the environment. The onset of such seizures involves any of a variety of auras: deja-vu, an unusual smell, a sudden intense emotional feeling, a sensory illusion such as micropsia (objects growing smaller) or macropsia (objects growing larger), or other sensory hallucination. There may be a cessation of activity with some minor motor activity such as lip smacking, walking aimlessly, or other automatisms. The seizures may also be accompanied by the unconscious performance of highly skilled activities such as driving a car. When the seizure ends, the individual is amnesic for events that took place during the seizure and may take minutes or hours to recover fully to consciousness. (12 Dec 1998) |
| epilepsy, partial | Epileptic seizures that originate at a specific location or focal point in the cortex of the brain and either remain localised or may generalise. These seizures occur without the loss of consciousness of the individual. The specific clinical symptoms depend on the area of the cortex involved. (12 Dec 1998) |
| fixed partial denture | A restoration of one or more missing teeth which cannot be readily removed by the patient or dentist; it is permanently attached to natural teeth or roots which furnish the primary support to the appliance. Synonym: bridge. (05 Mar 2000) |
| law of partial pressures | Each gas in a mixture of gases exerts a pressure proportionate to the percentage of the gas and independent of the presence of the other gases present. Synonym: law of partial pressures. (05 Mar 2000) |
| 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) |
