Plate (anatomy)

A plate in animal anatomy may refer to several things:

Contents

Flat bones (examples: bony plates, dermal plates) of vertebrates

  • an appendage of the Stegosauria group of dinosaurs
  • articulated armoured plates covering the head of thorax of Placodermi (literally "plate-skinned"), an extinct class of prehistoric fish (including skull, thoraxic and tooth plates)
  • bony shields of the Ostracoderms (armored jawless fishes) such as the dermal head armour of members of the class Pteraspidomorphi that include dorsal, ventral, rostral and pineal plates
  • plates of a carapace, such as the dermal plates of the shell of a turtle
  • dermal plates partly or completely covering the body of the fish in the order Gasterosteiformes that includes the sticklebacks and relatives
  • plates of dermal bones of the armadillo
  • Zygomatic plate, a bony plate derived from the flattened front part of the zygomatic arch (cheekbone) in rodent anatomy

    • Other flat structures

  • hairy plate-like keratin scales of the pangolin
  • Basal plate (disambiguation), several anatomy-related meanings

    • Other meanings in human anatomy

  • Alar plate, a neural structure in the embryonic nervous system
  • Cribriform plate, of the ethmoid bone (horizontal lamina) received into the ethmoidal notch of the frontal bone and roofs in the nasal cavities
  • Epiphyseal plate, a hyaline cartilage plate in the metaphysis at each end of a long bone
  • Lateral pterygoid plate of the sphenoid, a broad, thin and everted bone that forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone
  • Nail plate, the hard and translucent portion of the nail
  • Perpendicular plate of the ethmoid bone (vertical plate), a thin, flattened lamina, polygonal in form, which descends from the under surface of the cribriform plate, and assists in forming the septum of the nose
  • Scute, a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians and the feet of birds
  • Sclerite, a plate forming the exoskeleton of invertebrates
