The laminæ are two broad plates directed backward and medially from the pedicles.
They fuse in the middle line posteriorly, and so complete the posterior boundary of the vertebral foramen.
Their upper borders and the lower parts of their anterior surfaces are rough for the attachment of the ligamenta flava.
The name derives from the Latin word "lāmina," which refers to a thin plate, sheet, or layer.
