cortical plate a layer of compact bone overlying the spongiosa of the alveolar process on the vestibular and oral aspects of the mandible and maxilla.
deck plate roof plate.
dental plate a plate of acrylic resin, metal, or other material that is fitted to the shape of the mouth, and serves for the support of artificial teeth.

epiphyseal plate the thin plate of cartilage between the epiphysis and the shaft of a long bone; it is the site of growth in length and is obliterated by epiphyseal closure.
equatorial plate the collection of chromosomes at the equator of the spindle in mitosis.
foot plate footplate.
force plate force platform.
medullary plate neural plate.
muscle plate myotome (def. 2).
neural plate a thickened band of ectoderm in the midbody region of the developing embryo, which develops into the neural tube; called also medullary plate.
roof plate the unpaired dorsal longitudinal zone of the neural tube; called also dorsal plate and deck plate.
tarsal plate tarsus (def. 2).
ventral plate floor plate.
Thin flat plate of dense connective tissue, situated one in each eyelid, which gives it shape and firmness. Each tarsus extends from the orbital septum to the eyelid margin. The upper tarsal plate, shaped like the letter D placed on its side, is much larger than the lower. Its width is 11mm in the centre whereas the corresponding measurement in the lower tarsus, which is somewhat oblong in form, is 5mm. Each tarsus is about 29mm long and 1mm thick. Within each tarsus are the meibomian glands, approximately 25 in the upper and 20 in the lower. Syn. tarsal plate. See palpebral ligament; orbital septum.
1. a flat structure or layer, as a flat layer of bone.
2. used as a fracture repair medium, including compression plates.
3. to apply a culture medium to a glass plate.
4. to cultivate bacteria on such plates.
the primitive streak of the embryo.
primordial ventral horn of the spinal cord.
a strong crimping device for manually bending a plate for a tricky bit of orthopedic repair.
buttress plate (2)
a metal plate used in fracture repair to bridge and support a diaphyseal gap filled with a cancellous bone graft.
blind ending of the hindgut in the embryo.
a sievelike partition between the cranial and nasal cavities. The posterior surface is divided by the vertical ethmoidal crest into two concave surfaces which contain the olfactory bulbs. It contains many small perforations through which the filaments of the olfactory nerves pass.

the flat portion of the stapes.
region of modified skin around the nostrils in the embryonic carnivore or small ruminant.
region of modified skin around the nostrils in the embryo of cattle.
a thickened band of ectoderm in the midbody region of the developing embryo, which develops into the neural tube; called also medullary plate.
neutralization plate (2)
a bone plate placed to protect against the forces acting on the fracture site.
orthopedic bone plate
a metal plate screwed to the two fragments of a fractured bone to provide fixation and permit healing in correct alignment.
the unpaired dorsal longitudinal zone of the neural tube; called also dorsal plate and deck plate.
region of modified skin around the nostrils in the porcine embryo.
a mass of protoplasm in which a motor nerve ending is embedded.
metal or plastic plates may used to stabilize thoracolumbar or lumbar spinal fractures. With one plate on each side of a row of dorsal spinal processes, they are bolted together in the spaces between processes.
one of the plates of connective tissue forming the framework of either (upper or lower) eyelid.
the roof of the ethmoidal labyrinth of the internal ear.
tension band plate (2)
a bone plate placed on the tension side of a fracture and which counteracts tensile forces, converting them into compression forces at the fracture site.
