| 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) |
| adrenal cortex | <anatomy, endocrinology> This is the outer portion of the fattyacids and inhibit inflammation in allergic responses. Mineralocortoids regulate the levels of minerals such as sodium and potassium in the blood. (06 May 1997) |
| adrenal cortex injection | An obsolete treatment involving the parenteral administration of extract of the adrenal cortex; formerly used in treatment of Addison's disease. (05 Mar 2000) |
| agranular cortex | See: cerebral cortex. (05 Mar 2000) |
| amorphous fraction of adrenal cortex | Noncrystalline residue of an acetone extract of the adrenal cortex after crystalline steroids, e.g., corticosterone, deoxycorticosterone, etc., have been isolated. (05 Mar 2000) |
| association cortex | Generic term denoting the large expanses of the cerebral cortex that are not sensory or motor in the customary sense, but are involved in advanced stages of sensory information processing, multisensory integration, or sensorimotor integration. See: cerebral cortex. Synonym: association areas. (05 Mar 2000) |
| auditory cortex | Area of the temporal lobe concerned with hearing. (12 Dec 1998) |
| ganglionic layer of cerebellar cortex | The layer of Purkinje cells between the molecular and granular layers of the cerebellar cortex. Synonym: stratum neuronorum piriformium, ganglionic layer of cerebellar cortex, layer of piriform neurons, Purkinje's layer, stratum gangliosum cerebelli. (05 Mar 2000) |
| ganglionic layer of cerebral cortex | Layer 5 of the cortex cerebri. (05 Mar 2000) |
| parastriate cortex | See: visual cortex. (05 Mar 2000) |
| visual cortex | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
