| posterior palatal seal area | The soft tissues along the junction of the hard and soft palates on which pressure within the physiologic limits of the tissues can be applied by a denture to aid in the retention of the denture. Synonym: post dam area, postpalatal seal area. (05 Mar 2000) |
| postpalatal seal area | The soft tissues along the junction of the hard and soft palates on which pressure within the physiologic limits of the tissues can be applied by a denture to aid in the retention of the denture. Synonym: post dam area, postpalatal seal area. (05 Mar 2000) |
| precentral area | The cortex of the precentral gyrus. (05 Mar 2000) |
| precommissural septal area | A slender vertical whitish band immediately anterior to the lamina terminalis and anterior commissure; contrary to its name, it is not a cortical convolution but is the ventral continuation of the transparent septum. Synonym: area subcallosa, gyrus paraterminalis, gyrus subcallosus, pedunculus corporis callosi, corpus paraterminale, paraterminal body, paraterminal gyrus, peduncle of corpus callosum, precommissural septal area, subcallosal area, Zuckerkandl's convolution.

| prefrontal area | Cortex of the frontal lobe of the cerebral hemisphere, originally, the entire cortical expanse anterior to the central sulcus, including the agranular motor and premotor cortex (Brodmann's areas 4 and 6), the dysgranular cortex (area 8), and the granular frontal (prefrontal) cortex anterior to the latter, now more often refers to the granular frontal (prefrontal) cortex. Synonym: frontal area. (05 Mar 2000) |
| premotor area | A somewhat ill-defined term usually referring to the agranular cortex of Brodmann's area 6. Synonym: premotor area. (05 Mar 2000) |
| preoptic area | Region of hypothalamus between the anterior commissure and optic chiasm. (12 Dec 1998) |
| prestriate area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
| pretectal area | A narrow, transversally oriented rostral zone of the mesencephalic tectum, bounded caudally by the superior colliculus, rostrally by the habenular trigone, and laterally by the pulvinar thalami; the area contains several nuclei that receive fibres from the optic tract; it has bilateral efferent connections with the Edinger-Westphal nucleus of the oculomotor nuclear complex by way of which it mediates the pupillary light reflex. Synonym: pretectal region, pretectum. (05 Mar 2000) |
| primary visual area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
| problem area wetland | <ecology> A wetland that is difficult to identify because it may lack indicators of wetland hydrology and/or hydric soils, or its dominant plant species are more common of nonwetlands. (09 Oct 1997) |
| secondary aortic area | Region of the chest at the mid-left sternal bases where aortic diastolic murmurs are often best heard. (05 Mar 2000) |
| secondary visual area | Area of the occipital lobe concerned with vision. (12 Dec 1998) |
