In tetrapods, cervical vertebrae (sg.: vertebra) ... The laminae are narrow and thinner above than below; the vertebral foramen is large and of a triangular form.
Each vertebra (pl.: vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to their spinal segment and the particular species.
Laminoplasty is a surgical procedure that has been developed as an alternative to cervical laminectomy, which is used to treat cervical myelopathy. Laminoplasty reconstructs the vertebral lamina to decompress the spinal cord. The term laminoplasty means, "to create a hinge to lift the lamina." [1]
The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward. The articular surfaces are coated with hyaline cartilage. In the cervical vertebral column, the articular processes collectively form the articular pillars. These are the bony surfaces ...
Each ligamentum flavum connects the laminae of two adjacent vertebrae. [2] [3] They attach to the anterior portion of the upper lamina above, and the posterior portion of the lower lamina below. [1] They begin with the junction of the axis and third cervical vertebra, continuing down to the junction of the 5th lumbar vertebra and the sacrum. [2 ...
The laminae are thick and strong. They play a large role in the stability of the cervical spine alongside the laminae of C7. [2] The vertebral foramen is large, but smaller than the atlas. The transverse processes are very small, and each ends in a single tubercle.
The laminae of the thyroid cartilage: two leaf-like plates of cartilage that make up the walls of the structure. [2] The vertebral laminae: plates of bone that form the posterior walls of each vertebra, enclosing the spinal cord. [3] The laminae of the thalamus: the layers of thalamus tissue. [4]
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...
