| medullary chemoreceptor | The chemoreceptor's in or near the ventrolateral surface of the medulla that are stimulated by local acidity. (05 Mar 2000) |

| medullary cone | The tapering lower extremity of the spinal cord. Synonym: conus medullaris. (05 Mar 2000) |
| medullary cords | Cord's of dense lymphoid tissue between the sinuses in the medulla of a lymph node. Synonym: lymph cords. (05 Mar 2000) |
| medullary folds | Synonym: neural folds. (05 Mar 2000) |
| medullary groove | The gutter-like groove formed in the midline of the embryo's dorsal surface by the progressive elevation of the lateral margins of the neural plate; the ultimate dorsal fusion of the margins results in the formation of the neural tube. Synonym: medullary groove. (05 Mar 2000) |
| medullary laminae of thalamus | Layers of myelinated fibres that appear on transverse sections of the thalamus; the lamina medullaris externa marks the ventral and lateral borders of the thalamus and delimits it from the subthalamus and reticular nucleus of thalamus; the lamina medullaris interna is interposed between the mediodorsal and ventral nuclei of the thalamus and encloses the intralaminar nuclei (centromedian, paracentral, and central lateral nuclei). Synonym: laminae medullares thalami, medullary layers of thalamus. (05 Mar 2000) |

| medullary membrane | <anatomy> The layer of vascular connective tissue lining the medullary cavities of bone. Origin: NL, fr. Gr. + a bone. Source: Websters Dictionary (01 Mar 1998) |
| medullary nephrocalcinosis | <radiology> Primary hyperparathyroidism, renal tubular acidosis more than 70%, medullary sponge kidney, hypercalcaemia, hypercalcuria, sarcoidosis, bony metastases, Paget's disease, hypervitaminosis D, milk-alkali syndrome, Williams syndrome (in kids), idiopathic, oxalosis (with or without completely opaque kidneys; younger age) see also: renal calcification (12 Dec 1998) |
| medullary plate | <embryology> A region of embryonic ectodermal cells, called neuroectoderm, that lie directly above the notochord. During neurulation, they change shape, so as to produce an infolding of the neural plate (the neural fold) that then seals to form the neural tube. (04 Jul 1999) |
| medullary pyramid | One of a number of pyramidal masses seen on longitudinal section of the kidney; collectively, they constitute the renal medulla, and contain part of the secreting tubules and the collecting tubules. Synonym: pyramis renalis, malpighian pyramid, medullary pyramid. (05 Mar 2000) |
| medullary ray | The centre of the renal lobule, which has the shape of a small, steep pyramid, consisting of straight tubular parts; these may be either ascending or descending limbs of the nephronic loop or collecting tubules. Synonym: pars radiata lobuli corticalis renis, Ferrein's pyramid, processus ferreini. (05 Mar 2000) |
| medullary sarcoma | <tumour> A soft, extremely vascular sarcoma. (05 Mar 2000) |
| medullary sheath | <anatomy, neurology> An insulating layer surrounding vertebrate peripheral neurons, that dramatically increases the speed of conduction. It is formed by specialised Schwann cells, that can wrap around neurons up to 50 times. The exposed areas are called nodes of Ranvier: they contain very high densities of sodium channels and action potentials jump from one node to the next, without involving the intermediate axon, a process known as saltatory conduction. (18 Nov 1997) |
| medullary space | The central cavity and the cellular intervals between the trabeculae of bone, filled with marrow. (05 Mar 2000) |
