Lamina (anatomy) explained

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.
• Osseous spiral lamina, a feature of the bony canal of the cochlea
