| secondary pulmonary lobule | A pyramidal mass of lung tissue whose sides are bounded by the incomplete interlobular connective tissue septa and whose base, which is 1 to 2 cm in diameter, usually faces the pleural surface of the lung; lobule's that occupy a more central position in the lung are not well defined and are considered to consist of three to five pulmonary acini with proximate terminal bronchioles.

| simple lobule | The smaller anterior part of the posterior lobe of the cerebellum, demarcated by the primary fissure from the anterior lobe rostrally and from the large caudal subdivision of the posterior lobe caudally. Synonym: lobulus simplex. (05 Mar 2000) |
| slender lobule | The anterior portion of the posteroinferior lobule of the cerebellum, the posterior portion being the semilunar lobule inferior; the two correspond to the tuber of the vermis. Synonym: lobulus gracilis, slender lobule. (05 Mar 2000) |
| superior parietal lobule | The area of the convex surface of the parietal lobe of the cerebrum lying between the longitudinal fissure and the interparietal sulcus behind the posterior central gyrus; it is continuous with the precuneus on the medial aspect of the hemisphere. Synonym: lobulus parietalis superior, superior parietal gyrus. (05 Mar 2000) |
| superior semilunar lobule | The part of the superior surface of the cerebellar hemisphere lying rostral to the horizontal fissure, and adjoining the folium of the vermis. Synonym: lobulus semilunaris superior, anterior lunate lobule, crus I. (05 Mar 2000) |
| quadrangular lobule | The main portion of the superior part of each hemisphere of the cerebellum, corresponding to the monticulus of the vermis; it is divided into two portions, the anterior and the posterior crescentic lobules, corresponding to the culmen and the declive of the vermis. Synonym: lobulus quadrangularis, lobus quadratus, lobulus quadratus, quadrate lobe, quadrate lobule. (05 Mar 2000) |
| quadrate lobule | The main portion of the superior part of each hemisphere of the cerebellum, corresponding to the monticulus of the vermis; it is divided into two portions, the anterior and the posterior crescentic lobules, corresponding to the culmen and the declive of the vermis. Synonym: lobulus quadrangularis, lobus quadratus, lobulus quadratus, quadrate lobe, quadrate lobule. (05 Mar 2000) |
| inferior parietal lobule | The area of the parietal lobe of the cerebrum lying below the interparietal sulcus; it contains the angular and the supramarginal gyri. Synonym: lobulus parietalis inferior, inferior parietal gyrus. (05 Mar 2000) |
| inferior semilunar lobule | The part of the superior surface of the cerebellar hemisphere lying behind the horizontal fissure. Synonym: lobulus semilunaris inferior, crus II, posterior lunate lobule. (05 Mar 2000) |
| lobule | A subdivision of the lobes of the breast. (16 Dec 1997) |
| lobule of auricle | The lowest part of the auricle; it consists of fat and fibrous tissue not reinforced by the auricular cartilage. Synonym: lobulus auriculae, lobule of auricle. (05 Mar 2000) |
| acute respiratory failure | Loss of pulmonary function either acute or chronic that results in hypoxaemia or hypercarbia. (05 Mar 2000) |
| adult respiratory distress syndrome | <chest medicine, syndrome> A clinical syndrome that includes pulmonary insufficiency. It is a descriptive term that is applied to a variety of diffuse infiltrative processes in the lung. Manifestations include severe shortness of breath, rapid breathing and arterial hypoxaemia (low oxygen). Chest X-ray shows bilateral diffuse infiltrates. Treatment most often includes mechanical respiratory support. Causes include toxic gas (chlorine, NO2, smoke) exposure, severe metabolic derangement, gastric acid aspiration, pancreatitis, sepsis and trauma. Acronym: ARDS (12 Jul 2000) |
| alkalosis, respiratory | A state due to excess loss of carbon dioxide from the body. (12 Dec 1998) |
| anti-allergic and respiratory system agents | A collective term for drugs used to treat allergic reactions as well as those drugs that produce an effect on the respiratory system. (12 Dec 1998) |
