Short description: Anatomical feature


Lamina is a general anatomical term meaning "plate" or "layer".[1] It is used in both gross anatomy and microscopic anatomy to describe structures.

Some examples include:

  • The laminae of the thyroid cartilage: two leaf-like plates of cartilage that make up the walls of the structure.[2]
  • The vertebral laminae: plates of bone that form the posterior walls of each vertebra, enclosing the spinal cord.[3]
  • The laminae of the thalamus: the layers of thalamus tissue.[4]
  • The lamina propria: a connective tissue layer under the epithelium of an organ.[5]
  • The nuclear lamina: a dense fiber network inside the nucleus of cells.[6]
  • The lamina affixa: a layer of epithelium growing on the surface of the thalamus.
  • The lamina of Drosophila is the most peripheral neuropil of the insect visual system.
  • Lamina cribrosa with two different meanings.
