| valvula semilunaris tarini | A thin sheet of white matter, hidden by the cerebellar tonsil, attached along the peduncle of the flocculus and, at and near the midline, to the nodulus of the vermis; it is continuous caudally with the epithelial lamina and choroid plexus of the fourth ventricle. Synonym: velum medullare inferius, posterior medullary velum, Tarin's valve, valvula semilunaris tarini, velum semilunare, velum tarini. (05 Mar 2000) |
| plica semilunaris | The curved fold connecting the palatoglossal arch and palatopharyngeal arch above the supratonsillar fossa; it always contains lymphoid tissue. Synonym: plica semilunaris. (05 Mar 2000) |
| plica semilunaris conjunctivae | The semilunar fold formed by the palpebral conjunctiva at the medial angle of the eye, a fold of the conjunctival mucous membrane found in many animals; normally partially hidden in the medial canthus of the eye when at rest, it may be extended to cover part or all of the cornea in a winking-like action to clean the cornea, as in birds. Synonym: membrana nictitans, nictitating membrane, palpebra III, palpebra tertia, third eyelid. Synonym: plica lunata, plica semilunaris of eye, semilunar conjunctival fold. (05 Mar 2000) |
| plica semilunaris of colon | One of the folds of the wall of the colon between sacculations. Synonym: plica sigmoidea, semilunar fold of colon. (05 Mar 2000) |
| plica semilunaris of eye | The semilunar fold formed by the palpebral conjunctiva at the medial angle of the eye, a fold of the conjunctival mucous membrane found in many animals; normally partially hidden in the medial canthus of the eye when at rest, it may be extended to cover part or all of the cornea in a winking-like action to clean the cornea, as in birds. Synonym: membrana nictitans, nictitating membrane, palpebra III, palpebra tertia, third eyelid. Synonym: plica lunata, plica semilunaris of eye, semilunar conjunctival fold. (05 Mar 2000) |
| hiatus semilunaris | 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) |
| nodulus valvulae semilunaris | 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) |
| incisura semilunaris ulnae | The large saemicircular notch at the proximal extremity of the ulna between the olecranon and coronoid processes that articulates with the trochlea of the humerus. Synonym: incisura trochlearis, incisura semilunaris ulnae, semilunar notch. (05 Mar 2000) |
