| semilunar fold of colon | One of the folds of the wall of the colon between sacculations. Synonym: plica sigmoidea, semilunar fold of colon. (05 Mar 2000) |
|---|---|
| semilunar ganglion | The semilunar-shaped ganglion containing the cells of origin of most of the sensory fibres of the trigeminal nerve. It is situated within the dural cleft on the cerebral surface of the petrous portion of the temporal bone and gives off the ophthalmic, maxillary, and part of the mandibular nerves. (12 Dec 1998) |
| semilunar hiatus | A deep, narrow groove in the lateral wall of the middle meatus of the nasal cavity, into which the maxillary sinus, the frontonasal duct, and the middle ethmoid cells open. Synonym: hiatus semilunaris, hiatus ethmoidalis. (05 Mar 2000) |
| semilunar line | The slight groove in the external abdominal wall parallel to the lateral edge of the rectus sheath. Synonym: semilunar line, Spigelius' line. (05 Mar 2000) |
| semilunar notch | A wide, shallow notch on the anterior surface of the cerebellum occupied laterally by the superior cerebellar peduncles and the inferior quadrigeminal bodies medially. Synonym: anterior notch of cerebellum, incisura cerebelli anterior, semilunar notch. (05 Mar 2000) |
| semilunar valve | <anatomy, cardiology> Refers to a type of valve, aortic or pulmonic valves. (27 Sep 1997) |
| nodule of semilunar valve | A nodule at the centre of the free border of each semilunar valve at the beginning of the pulmonary artery and aorta. Synonym: nodulus valvulae semilunaris, Arantius' nodule, Bianchi's nodule, corpus arantii, Morgagni's nodule. (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) |
| 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) |
| internal semilunar fibrocartilage of knee joint | <anatomy> A flat disc-shaped ligament which stabilises and supports the inner aspect of the knee joint. Commonly injured in knee sprains. (27 Sep 1997) |
| Traube's semilunar space | A crescentic space about 12 cm wide, bounded medially by the left border of the sternum, above by an oblique line from the sixth costal cartilage to the lower border of the eighth or ninth rib in the mid-axillary line and below by the costal margin; the percussion tone here is normally tympanitic, because of the underlying stomach, but is modified by pulmonary emphysema, a pleural effusion, or an enlarged spleen. (05 Mar 2000) |
| external semilunar fibrocartilage | A flat disc-shaped ligament which stabilises and supports the outer aspect of the knee joint. Not as commonly injured as the medical meniscus ligament in knee sprains. (27 Sep 1997) |
| lunula of semilunar valve | The free border of a semilunar valve at each side of the nodulus valvulae semilunaris. Synonym: lunula valvulae semilunaris. (05 Mar 2000) |
| abducens nucleus | Nucleus of abducent nervenucleus abducentis, a group of motor neurons in the lower part of the pons, innervating the lateral rectus muscle of the eye; unique among motor cranial nerve nuclei in that it consists of two distinct populations of neurons: neurons that give rise to fibres forming the abducens nerve root and those internuclear neurons whose processes cross the midline, ascend in the opposite medial longitudinal fasciculus, and terminate upon specific oculomotor neurons; considered a primary centre for mechanisms controlling conjugate horizontal gaze. Synonym: nucleus nervi abducentis. (05 Mar 2000) |
| accessory cuneate nucleus | A cell group lateral to the cuneate nucleus which receives posterior-root fibres corresponding to the proprioceptive innervation of the arm and hand; it projects to the cerebellum by way of the cuneocerebellar tract, and can be considered the upper-extremity equivalent of the thoracic nucleus. Synonym: nucleus cuneatus accessorius, external cuneate nucleus, lateral cuneate nucleus, Monakow's nucleus. (05 Mar 2000) |
