| nervus cardiacus cervicalis medius | <anatomy, nerve> One of the cardiopulmonary splanchnic nerves conveying postsynaptic sympathetic fibres running downward, from the middle cervical ganglion along the subclavian artery (on the left) or the brachiocephalic (on the right side) to join the cardiac plexus. Synonym: nervus cardiacus cervicalis medius. (05 Mar 2000) |
| nodus rectalis medius | A lymph node along the middle rectal artery that receives afferents from the pararectal nodes and sends efferents to the internal iliac nodes. Synonym: middle rectal node, nodus rectalis medius. (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) |
