Lamina
Lamina
Lamina (pronounced: /ˈlæmɪnə/) is a term used in anatomy, botany, and mycology. It has its roots in the Latin word lamina, which means "thin plate" or "layer".
Anatomy
In anatomy, a lamina refers to a thin layer, plate, or scale of sedimentary rock, organic tissue, or other material. It is often used in the context of the vertebral column where the lamina of the vertebra can be a crucial structure in certain medical conditions. For example, a laminectomy is a surgical procedure that removes a portion of the vertebral lamina to relieve pressure on the spinal cord or nerves.
Botany
In botany, the lamina is also known as the blade of a leaf. It is the broad, flat part of the leaf where most photosynthesis occurs. The size, shape, and texture of the lamina can vary greatly from plant to plant, and these characteristics are often used in plant identification.
Mycology
In mycology, lamina refers to the layer of a fungus where spore-producing cells, known as basidia, are located. This layer is typically found on the underside of the mushroom cap.
