| AChA | anterior choroidal artery |
| sulcus for transverse sinus | The groove on the inner surface of the occipital bone marking the course of the transverse sinus; the tentorium is attached to its margins. Synonym: sulcus sinus transversi, sulcus for transverse sinus. (05 Mar 2000) |

| sulcus for vena cava | A groove on the posterior surface of the liver between the caudate lobe and the right lobe which gives passage to the inferior vena cava. Synonym: sulcus venae cavae, fossa venae cavae, sulcus for vena cava. (05 Mar 2000) |
| sulcus for vertebral artery | <anatomy, artery> The sulcus on the superior aspect of the posterior arch of the atlas that transmits the vertebral artery medially toward the foramen magnum. Synonym: sulcus arteriae vertebralis, sulcus for vertebral artery. (05 Mar 2000) |
| sulcus frontalis inferior | A sagittal fissure on the lateral convex surface of each frontal lobe of the cerebrum demarcating the middle from the inferior frontal gyrus. Synonym: sulcus frontalis inferior. (05 Mar 2000) |
| sulcus frontalis medius | A relatively shallow sagittal fissure of the brain dividing the middle frontal convolution into an upper and lower part; this sulcus is found only in humans and anthropoid apes; at its anterior extremity it bifurcates, the two branches spreading out laterally and constituting the frontomarginal sulcus. Synonym: median frontal sulcus, sulcus frontalis medius. (05 Mar 2000) |
| sulcus frontalis superior | A sagittal fissure on the superior surface of each frontal lobe of the cerebrum starting from the precentral sulcus; it forms the lateral boundary of the superior frontal convolution. Synonym: sulcus frontalis superior. (05 Mar 2000) |
| sulcus frontomarginalis | A relatively shallow sagittal fissure of the brain dividing the middle frontal convolution into an upper and lower part; this sulcus is found only in humans and anthropoid apes; at its anterior extremity it bifurcates, the two branches spreading out laterally and constituting the frontomarginal sulcus. Synonym: median frontal sulcus, sulcus frontalis medius. (05 Mar 2000) |
| sulcus gingivalis | The space between the surface of the tooth and the free gingiva. Synonym: sulcus gingivalis, gingival crevice, gingival space, subgingival space. (05 Mar 2000) |
| sulcus gluteus | A prominent fold that marks the upper limit of the thigh from the lower limit of the buttock; it coincides with the lower border of the gluteus maximus muscle; the furrow between the buttock and thigh. Synonym: sulcus gluteus, gluteal furrow. (05 Mar 2000) |
| sulcus hamuli pterygoidei | A groove at the base of the hamular process which forms a pulley for the tendon of the tensor veli palatini muscle. Synonym: sulcus hamuli pterygoidei, sulcus of pterygoid hamulus. (05 Mar 2000) |
| sulcus hippocampi | A shallow groove between the dentate gyrus and the parahippocampal gyrus; the remains of a fissure extending deep into the hippocampus between Ammon's horn and the dentate gyrus which becomes obliterated during foetal development. Synonym: sulcus hippocampi, dentate fissure, fissura dentata, fissura hippocampi, hippocampal fissure. (05 Mar 2000) |
| sulcus hypothalamicus | A groove in the lateral wall of the third ventricle on either side leading from the interventricular foramen to the aditus ad aqueductum cerebri; the sulcus-demarcated boundary between dorsal thalamus and hypothalamus. Synonym: sulcus hypothalamicus, Monro's sulcus. (05 Mar 2000) |

| sulcus infrapalpebralis | The hollow or furrow below the lower eyelid. Synonym: sulcus infrapalpebralis. (05 Mar 2000) |
| sulcus intermedius posterior | A longitudinal furrow between the posterior median and the posterolateral sulci of the spinal cord in the cervical region, marking the gracile fasciculus from the cuneate fasciculus. Synonym: sulcus intermedius posterior, posterior intermediate groove. (05 Mar 2000) |
