(plat) [Fr. plate, something flat]
1. A thin, flattened part or portion, such as a flattened process of a bone. Synonym: lamella; lamina
2. 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 plate

In the embryo, the upper (dorsal) half of the neural tube (above the sulcus limitans).
Synonym: alar lamina of neural tube

auditory plate

The bony roof of the external auditory meatus.

axial plate

The primitive streak of the embryo.

belay plate

A 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 plate

In 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 template

bone plate

A flat, round or oval decalcified bone or metal disk, employed in pairs, used in approximation.

chorionic plate

The fetal surface of the placenta.

cortical plate

The compact layers of bone forming the surfaces of the alveolar processes of the mandible and maxilla.

cribriform plate

1. 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 plate

The roof plate of the embryonic neural tube.

dental plate

An 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 plate

One of two prominences of the notochord in the embryo.

epiphyseal plate

The 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: illustration

equatorial plate

The platelike mass of chromosomes at the equator of the spindle in cell division.

floor plate

In 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 plate

force plate

A 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 plate

Epiphyseal plate.

image plate

A 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 plate

The central portion of the ectoderm in the embryo developing into the neural canal.

muscle plate

In the somite, the myotome from which the striated muscles are formed.

neural plate

A thickened band of ectoderm along the dorsal surface of an embryo. The nervous system develops from this tissue.

palate plate

The part of the palatine bone forming the dorsal half of the roof of the mouth.

polar plate

In some cells, the flattened platelike bodies seen at the end of the spindle during mitosis.

pterygoid plate

Either 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 plate

A device that moves fluids in a specific direction.

tarsal plate

The dense connective tissue structure that supports the eyelid. It was formerly called tarsal cartilage; however, it is not true cartilage.

tympanic plate

The bony plate between the anterior wall of the external auditory meatus and the tympanum.

ventral plate

Floor plate.

Further studies are needed to ascertain whether the stage of development of growth plates is a determinant of the extent of the intra-articular inflammatory response to traumatic knee injuries.
MV isolated from growth plate cartilage shows high BMP expression.
Unfortunately, many of these injuries are poorly managed, resulting in overuse strain on the growth plate and subsequent irregular and/or partial healing.
Previous research has focused on histological examination of growth plate remnants or fibrous tissue in lesions [2, 3, 6, 7] and revealed the presence of widened physes with sclerotic margins or fibrous tissue without physeal remnants.
Death of cartilage cells in the growth plate and articular surface is the basic pathologic feature, and this can result in growth retardation and secondary osteoarthrosis [4].
Longitudinal bone growth before and after birth takes place in the growth plate located at the epiphyses of long bones via an endochondral ossification process in which a hypertrophic cartilage template is made, calcified, and invaded by blood vessels and then converted to trabecular bone through the action of bone forming cells, osteoblasts, and bone resorbing cells, osteoclasts [1].
In group 1, one case of premature growth plate closure occurred (Table 2).
Salter-Harris type II fracture refers to a physeal injury in which the fracture extends along the growth plate then out through a portion of the metaphysis, producing a triangular shaped metaphyseal fragment referred to as the "Thurston Holland sign." This is the most common form of physeal injury and has historically been associated with a good prognosis, though recent data now suggest that this injury is associated with a greater risk of growth impairment than previously thought [5].
OSD is characterized by inflammation of the growth plate just below the knee, the result of repetitive strain on the secondary ossification center of the tibial tuberosity.
