Synonym: membrana suprapleuralis, Sibson's aponeurosis, Sibson's fascia. (05 Mar 2000) |
| Sibson's muscle | <anatomy> An occasional independent muscular fasciculus between the scalenus anterior and medius, and having the same action and innervation. Synonym: musculus scalenus minimus, Albinus' muscle, Sibson's muscle, smallest scalene muscle. (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) |
