What is the function of the lamina in the vertebrae?

What is the function of the lamina in the vertebrae?

The lamina is is the roof of the spinal canal that provides support and protection for the backside of the spinal cord.

What are lamina bones?

lamina: flat plates of bone originating from the pedicles of the vertebral body that form the posterior outer wall of the spinal canal and protect the spinal cord. Sometimes called the vertebral arch.

Is a laminectomy a major surgery?

A cervical laminectomy can take1 to 3 hours to perform. It is a major spine surgery in a sensitive location on the backbone. It is usually performed only when symptoms are not relieved with non-invasive therapies such as: rest.

Does lamina grow back after laminectomy?

A laminectomy removes the entire lamina. Removal of the lamina allows more room for the nerves of the spine and reduces the irritation and inflammation of the spinal nerves. The lamina does not grow back. Instead, scar tissue grows over the bone, replacing the lamina, and protects the spinal nerves.

What is the function of lamina?

The flat and usually thin region of the leaf, the leaf lamina has an important role in giving the special status to the leaf. The lamina plant leaf, as clear from the above article, consists of the chloroplasts and stomata, crucial for photosynthesis and gaseous exchange respectively.

What is lamina answer?

Answer: a thin layer, plate, or scale of sedimentary rock, organic tissue, or other material. Explanation: Lamina is a general anatomical term meaning “plate” or “layer”. Some examples include: The laminae of the thyroid cartilage: two leaflike plates of cartilage that make up the walls of the structure.

Is the lamina a bone?

The lamina is a posterior arch of the vertebral bone lying between the spinous process (which juts out in the middle) and the more lateral pedicles and the transverse processes of each vertebra.

What is called lamina?

Lamina is a general anatomical term meaning “plate” or “layer”. It is used in both gross anatomy and microscopic anatomy to describe structures. The vertebral laminae: plates of bone that form the posterior walls of each vertebra, enclosing the spinal cord. The laminae of the thalamus: the layers of thalamus tissue.

What is a lamina in the spinal cord?

The lamina is the flattened or arched part of the vertebral arch, forming the roof of the spinal canal; the posterior part of the spinal ring that covers the spinal cord or nerves.

What is lamina in simple words?

1 : a thin plate or scale : layer. 2 : either of two broad, flat plates of bone of a vertebra that is fused with and extends from the pedicle to the median line of the neural arch to form the base of the spinous process and that along with the pedicle forms the posterior part of the vertebral foramen.

What does the lamina do?

Function of the lamina. A lamina is a bony structure, existing in pairs, on each of the spinal vertebrae, which provides a roof for the spinal canal and protects the back of the spinal cord. The spine is constructed in a way to both protect the spinal cord as well as support the upper body, while still allowing for movement.

What are the parts of the vertebrae?

Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

What is C3 vertebrae?

The upper section of the cervical spine consists of the first cervical vertebrae (C1) and the second cervical vertebrae (C2). The lower section consists of the third cervical vertebrae (C3) through seventh cervical vertebrae (C7). These spinal bones attach to the thoracic spine and work together to support the head.
