ep·i·phys·i·al plate [TA] the disk of hyaline cartilage between the metaphysis and the epiphysis of an immature long bone that permits the bone to grow longer. Synonym(s): lamina epiphysialis [TA], growth plateep·i·phys·i·al plate (ep'i-fiz'ē-ăl plāt) [TA] The disc of cartilage between the metaphysis and the epiphysis of an immature long bone permitting growth in length. Synonym(s): cartilago epiphysialis [TA] , growth plate. plate (plat) [Fr. plate, something flat] 1. A thin, flattened part or portion, such as a flattened process of a bone. Synonym: lamella; lamina2. An incorrect reference to a full denture.3. A shallow covered dish for culturing microorganisms.4. To inoculate and culture microorganisms in a culture plate.alar plateIn the embryo, the upper (dorsal) half of the neural tube (above the sulcus limitans). Synonym: alar lamina of neural tubeauditory plateThe bony roof of the external auditory meatus.axial plateThe primitive streak of the embryo.belay plateA metal, steel, or aluminum plate that has one or more slots in it, designed to weave a rope through, to create friction with a carabiner.bite plateIn dentistry, a plate made of some suitable plastic material into which the patient bites in order to have a record of the relationship between the upper and lower jaws. The device may be reinforced with wire and used as a splint in the mouth or to treat temporomandibular joint difficulties. Synonym: interocclusal record; occlusal templatebone plateA flat, round or oval decalcified bone or metal disk, employed in pairs, used in approximation.chorionic plateThe fetal surface of the placenta.cortical plateThe compact layers of bone forming the surfaces of the alveolar processes of the mandible and maxilla.cribriform plate1. The thin, perforated, medial portion of the horizontal plate of the ethmoid bone; the olfactory foramina are passages for the olfactory nerve.2. Alveolar bone, the spongy bone that makes up the wall of the socket for a tooth; found in the maxillae and mandible.deck plateThe roof plate of the embryonic neural tube.dental plateAn old term for the denture base of metal or acrylic material that rests on the oral mucosa and to which artificial teeth are attached; by extension, incorrectly used to mean the complete denture.dorsal plateOne of two prominences of the notochord in the embryo. EPIPHYSEAL PLATEepiphyseal plateThe thin layer of cartilage between the epiphysis and the shaft of a bone. Growth in length of the bone occurs at this layer. Synonym: growth plate See: illustrationequatorial plateThe platelike mass of chromosomes at the equator of the spindle in cell division.floor plateIn the embryonic neural tube, the wedge of cells in the ventral midline. These cells are primitive radial glia and do not give rise to neurons. The ventral commissures and decussations eventually develop through this structure. Synonym: ventral plateforce plateA flat, floor-mounted instrument, similar to a scale, for determining weight-bearing loads and biomechanical forces placed on the foot during walking or running. It is used to detect subtle body movements in order to identify postural deficits, or to develop (in athletes or people with balance disorders) more fluid and safer coordination and locomotion. growth plateEpiphyseal plate.image plateA photostimulable image detector used in computed tomography in place of x-ray cassettes. It gathers the energy from x-ray photons on a layer of phosphor that can repeatedly store and release information in digitized form for enhancement, recording, and image display. medullary plateThe central portion of the ectoderm in the embryo developing into the neural canal.muscle plateIn the somite, the myotome from which the striated muscles are formed.neural plateA thickened band of ectoderm along the dorsal surface of an embryo. The nervous system develops from this tissue. palate plateThe part of the palatine bone forming the dorsal half of the roof of the mouth.polar plateIn some cells, the flattened platelike bodies seen at the end of the spindle during mitosis.pterygoid plateEither of a pair of thin, bony processes that arise from the sphenoid bone. They are termed medial and lateral pterygoid plates on each side, serve to bound the infratemporal fossa, and give origin to muscles of mastication. pusher plateA device that moves fluids in a specific direction.tarsal plateThe dense connective tissue structure that supports the eyelid. It was formerly called tarsal cartilage; however, it is not true cartilage. tympanic plateThe bony plate between the anterior wall of the external auditory meatus and the tympanum.ventral plateFloor plate.Growth plateThe place in long bones where growth occurs during childhood.Mentioned in: RicketsFinancialSeegrowth |
