| axial plate | The primitive streak of an embryo. (05 Mar 2000) |
|---|---|
| basal plate of neural tube | The ventral division of the lateral walls of the neural tube in the embryo; it contains neuroblasts giving rise to somatic and visceral motor neurons. Synonym: lamina basalis, basal plate of neural tube, lamina ventralis, ventral plate of neural tube. (05 Mar 2000) |
| buttress plate | A metal plate used to support the internal fixation of a fracture. (05 Mar 2000) |
| cardiogenic plate | The thickened layer of splanchnic mesoderm from which the cardiopericardial primordia of very young embryos are derived. (05 Mar 2000) |
| palatal plate | A partial denture major connector that has an anteroposterior width in excess of two maxillary premolars. (05 Mar 2000) |
| paper plate | A thin plate of ethmoid bone forming part of the medial wall of the orbit and the lateral wall for the ethmoidal labyrinth. Synonym: lamina orbitalis ossis ethmoidalis, lamina papyracea, orbital lamina of ethmoid bone, orbital layer of ethmoid bone, orbital plate, paper plate, papyraceous plate. (05 Mar 2000) |
| parachordal plate | The cartilage primordia of the base of the skull situated on either side of the cephalic part of the notochord. (05 Mar 2000) |
| ventral plate | Ventral midline thinning of the developing neural tube, a continuity between the basal laminae of either side; opposite of roof plate. Synonym: ventral plate. (05 Mar 2000) |
| ventral plate of neural tube | The ventral division of the lateral walls of the neural tube in the embryo; it contains neuroblasts giving rise to somatic and visceral motor neurons. Synonym: lamina basalis, basal plate of neural tube, lamina ventralis, ventral plate of neural tube. (05 Mar 2000) |
| parietal plate | The outer of the two layers of the lateral plate mesoderm, which becomes associated with the ectoderm; the ectoderm and parietal plate mesoderm together constitute the somatopleure, the lamina of the ethmoid bone that forms the nasal septum. (05 Mar 2000) |
| vertical plate | Flat portion of a bone which lies within or closely approximates a vertical plane. See: perpendicular plate of ethmoid bone, perpendicular plate of palatine bone. Synonym: lamina perpendicularis, pars perpendicularis, vertical plate. (05 Mar 2000) |
| visceral plate | The inner of the two layers of the lateral mesoderm; the splanchnic mesoderm that becomes associated with the endoderm and together with it constitutes the splanchnopleure. (05 Mar 2000) |
| medial plate of pterygoid process | The smaller and more medial of the two bony plates extending downward from the point of union of the body and greater wing of the sphenoid bone on either side. Ending inferiorly in the pterygoid hamulus. Synonym: lamina medialis processus pterygoidei, medial plate of pterygoid process. (05 Mar 2000) |
| medial pterygoid plate | The smaller and more medial of the two bony plates extending downward from the point of union of the body and greater wing of the sphenoid bone on either side. Ending inferiorly in the pterygoid hamulus. Synonym: lamina medialis processus pterygoidei, medial plate of pterygoid process. (05 Mar 2000) |
| cell plate | <plant biology> Region in which the new cell wall forms after the division of a plant cell. In the plane of the equator of the spindle a disc like structure, the phragmoplast forms, into which are inserted pole derived microtubules. Golgi derived vesicles containing pectin come together and fuse at the plate which develops from the centre outwards and eventually fuses with the plasma membrane thereby separating the daughter cells.
