Bone: Lamina of the vertebral arch
A typical thoracic vertebra, viewed from above. (Lamina labeled at bottom left.)
A cervical vertebra. (Lamina labeled at bottom right.)
Latin	l. arcus vertebrae
Gray's	subject #20 97

The laminæ are two broad plates, extending dorsally and medially from the pedicles, fusing to complete the roof of the vertebral arch.

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.
