The lamina, or “bony arch,” protects and supports the back part of your spinal cord on your vertebrae. Removing the lamina relieves pressure on your nerves and spinal cord by making more room in your spinal canal (the tunnel that holds your spinal cord).
Removing the rear part of a vertebra, called the lamina, makes extra space in the spinal canal. This can relieve pressure on the spinal cord or nerves.
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]
Laminectomy is a type of surgery in which a surgeon removes part or all of the vertebral bone (lamina). This helps ease pressure on the spinal cord or the nerve roots that may be caused by injury, herniated disk, narrowing of the canal (spinal stenosis), or tumors.
The lamina is the back part of each vertebra (spinal bone) and covers the spinal canal, the area around the spinal cord. Both procedures reduce pressure on the spinal cord or spinal nerves to relieve pain.
The lamina is a small but essential part of the spine, contributing to its protection, stability, and flexibility. Understanding its structure can help you appreciate the spine’s complexity and the importance of maintaining spinal health.
The meaning of LAMINA is a thin plate or scale : layer.
The lamina is a thin, plate-like section of bone that forms part of the protective ring around the spinal cord. The lamina is a flat, bony plate located on the posterior side of each vertebra. It consists of two symmetrical plates of bone that extend backward from the main vertebral body.
