cribriform plate (krib´rform´),

n 1. the aveolar bone that forms the tooth socket and to which the periodontal ligament is attached (radiographically presents as the lamina dura).
2. the horizontal plate of the ethmoid bone that is perforated with foramina for the olfactory nerves.

axial plate

the primitive streak of the embryo.

basal plate

primordial ventral horn of the spinal cord.

plate bender

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.

cloacal plate

blind ending of the hindgut in the embryo.

cribriform plate

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.

deck plate

see roof plate.

dorsal plate

see roof plate.

equatorial plate

the collection of chromosomes at the equator of the spindle in mitosis.

floor plate

the unpaired ventral longitudinal zone of the neural tube; called also ventral plate.

foot plate

the flat portion of the stapes.

medullary plate

neural plate.

muscle plate

myotome (2).

nasal plate

region of modified skin around the nostrils in the embryonic carnivore or small ruminant.

nasolabial plate

region of modified skin around the nostrils in the embryo of cattle.

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.

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.

roof plate

the unpaired dorsal longitudinal zone of the neural tube; called also dorsal plate and deck plate.

rostral plate

region of modified skin around the nostrils in the porcine embryo.

sole plate

a mass of protoplasm in which a motor nerve ending is embedded.

spinal plate

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.

tarsal plate

one of the plates of connective tissue forming the framework of either (upper or lower) eyelid.

tectorial plate

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.

ventral plate

floor plate.

cribriform plate 

This is a part of the sclera which is situated at the site of attachment of the optic nerve, 3 mm to the inner side of and just above the posterior pole of the eye. There, the sclera is a thin sieve-like membrane through which pass fibres of the optic nerve. Syn. lamina cribrosa (although this term also refers to the striated portion of the bulbar optic nerve which includes the cribriform plate). See myelinated nerve fibres.
