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

Some examples include:

  • The laminae of the thyroid cartilage: two leaflike plates of cartilage that make up the walls of the structure
  • The vertebral laminae: plates of bone that form the posterior walls of each vertebra, enclosing the spinal cord
  • The laminae of the thalamus: the layers of thalamus tissue
  • The lamina propria: a connective tissue layer under the epithelium of an organ
