| transverse palatine ridge | A masticatory vestige on the hard palate; one of several irregular, sometimes branching, crests of soft tissue that radiate from the region of the incisive papillae at their most anterior parts and extend a slight distance backward, crossing the hard palate and reaching laterally for variable distances. Synonym: plica palatina transversa, ruga palatina, transverse palatine ridge. (05 Mar 2000) |
|---|---|
| transverse palatine suture | Line of union of the palatine processes of the maxillae with the horizontal plates of the palatine bones. Synonym: sutura palatina transversa. (05 Mar 2000) |
| lesser palatine artery | <anatomy, artery> One of several posterior branches of the descending palatine in the greater palatine canal, distributed to the soft palate and tonsil. Synonym: arteria palatina minor. (05 Mar 2000) |
| lesser palatine foramina | Openings on the hard palate of palatine canals passing vertically through the tuberosity of the palatine bone and transmitting the smaller palatine nerves and vessels. Synonym: foramina palatina minora, posterior palatine foramina. (05 Mar 2000) |
| lesser palatine nerves | Usually two, these nerves emerge through the lesser palatine foramina and supply the mucosa and glands of the soft palate and uvula; they are branches of the pterygopalatine ganglion and contain postsynaptic parasympathetic and sensory fibres of the maxillary nerve. Synonym: nervi palatini minores. (05 Mar 2000) |
| alveolobuccal groove | The upper and lower half of the buccal vestibule on each side. Synonym: alveolobuccal sulcus, gingivobuccal groove, gingivobuccal sulcus. (05 Mar 2000) |
| alveololabial groove | The upper and lower half of the labial vestibule, in the embryo, the groove formed by the deepening of the labial sulcus; its inner wall becomes incorporated with the alveolar process of the mandible or the maxilla, and its outer wall with the lips and cheeks. Synonym: alveololabial sulcus, gingivolabial groove, gingivolabial sulcus. (05 Mar 2000) |
| alveololingual groove | That part of the oral cavity proper, on each side of the frenulum linguae, between the tongue and the mandibular alveolar process or ridge, in the embryo, the groove on each side between the lingual primordium and the alveolar elevations of the mandible. Synonym: alveololingual sulcus, gingivolingual groove, gingivolingual sulcus. (05 Mar 2000) |
| anterior auricular groove | A notch between the supratragic tubercle and the crus of the helix. Synonym: incisura anterior auris, anterior auricular groove, auricular notch, sulcus auriculae anterior. (05 Mar 2000) |
| anterior intermediate groove | A furrow occasionally seen in the adult between the anterior median fissure and the anterior lateral sulcus of the spinal cord but usually present only in the foetus. It indicates the lateral border of the anterior corticospinal fasciculus. Synonym: anterior intermediate groove, sulcus intermedius anterior. (05 Mar 2000) |
| anterior interventricular groove | A groove on the anterosuperior surface of the heart, marking the location of the septum between the two ventricles. Synonym: sulcus interventricularis anterior, crena cordis. (05 Mar 2000) |
| anterolateral groove | An indistinct furrow on the ventral surface of the spinal cord and medulla oblongata, on either side marking the line of exit of the anterior nerve roots. Synonym: sulcus lateralis anterior, anterolateral groove. (05 Mar 2000) |
| anteromedian groove | The longitudinal groove in the midline of the anterior aspect of the medulla oblongata; it is the medullary equivalent of the anterior median fissure of the spinal cord and ends at the foramen caecum posterius; its caudal part is obliterated by the decussation of the pyramids. Synonym: fissura mediana anterior medullae oblongatae, anteromedian groove. (05 Mar 2000) |
| atrioventricular groove | A groove on the outer surface of the heart marking the division between the atria and the ventricles. Synonym: sulcus coronarius, atrioventricular groove, atrioventricular sulcus, auriculoventricular groove, coronary sulcus. (05 Mar 2000) |
| auriculoventricular groove | A groove on the outer surface of the heart marking the division between the atria and the ventricles. Synonym: sulcus coronarius, atrioventricular groove, atrioventricular sulcus, auriculoventricular groove, coronary sulcus. (05 Mar 2000) |
