| primitive pit | The depression in the primitive node that serves to connect the notochordal canal with the surface ectoderm and the yolk sac. These connections are referred to as the neurenteric canal. (05 Mar 2000) |

| primitive reticular cell | A cell with processes making contact with those of other similar cell's to form a cellular network; along with the network of reticular fibres, the reticular cell's form the stroma of bone marrow and lymphatic tissues. (05 Mar 2000) |
| primitive ridge | One of the paired ridge's on either side of the primitive groove. (05 Mar 2000) |
| primitive streak | An ectodermal ridge in the midline at the caudal end of the embryonic disk from which arises the intraembryonic mesoderm; achieved by inward and then lateral migration of cells; in human embryos, it appears on day 15 and gives a cephalocaudal axis to the developing embryo. Synonym: germinal streak. (05 Mar 2000) |
| neuroectodermal tumour, primitive | A malignant brain tumour sharing common features and biologic properties with medulloblastoma. Some pathologists and clinicians use the terms interchangeably: they both can disseminate throughout the nervous system and, in some cases, systemically. most lesions arise from the posterior fossa in children under five years of age. The tumour often produces hydrocephalus and symptoms of increased intracranial pressure. Papilledema is often present. (12 Dec 1998) |
| acromial arterial network | A vascular network between the acromion and the skin of the shoulder, formed by anastomoses of the acromial branch of the suprascapular artery with the acromial branch of the thoracoacromial artery. Synonym: rete acromiale, acromial plexus. (05 Mar 2000) |
| arteriolar network | A vascular network formed by anastomoses between minute arteries just before they become capillaries. Synonym: rete arteriosum. (05 Mar 2000) |
| articular network | A vascular rete in the neighborhood of a joint, where such arrangements are common, enabling a collateral circulation by which blood will be supplied distal to the joint regardless of compromises resulting from joint position. Synonym: circulus articularis vasculosus, rete vasculosum articulare, articular network. (05 Mar 2000) |

Synonym: circulus articularis vasculosus, rete vasculosum articulare, articular network. (05 Mar 2000) |
| articular vascular network of elbow | Vascular networks in the region of the elbow, composed of anastomoses between branches of the radial and middle collateral, superior and inferior ulnar collateral, radial recurrent, interosseous recurrent, and recurrent ulnar arteries. Synonym: rete articulare cubiti. (05 Mar 2000) |
| articular vascular network of knee | An arterial network over the front and sides of the knee, formed by branches of the descending genicular artery, of the five genicular arteries from the popliteal, of the anterior tibial recurrent, and of the fibular circumflex branch of the posterior tibial. Synonym: rete articulare genus. (05 Mar 2000) |
| calcaneal arterial network | A superficial network over the calcaneus, formed by branches of the peroneal and posterior tibial arteries and twigs from the malleolar retia. Synonym: rete calcaneum. (05 Mar 2000) |
| patellar network | The superficial portion of the articular vascular network of the knee. Synonym: rete patellae. (05 Mar 2000) |
| medial malleolar network | A network over the medial malleolus formed by branches from the anterior and posterior medial malleolar and medial tarsal arteries. Synonym: rete malleolare mediale. (05 Mar 2000) |
| peritarsal network | The lymphatic vessels along the margin of the eyelid. (05 Mar 2000) |
