After the incision through the skin, the lumbar muscles are visualized and these are pushed to the sides to visualize the back of the spinal bones. The most prominent bone initially seen is the spinous process which flows down towards the spinal lamina.

Primary Afferent Stimulation Differentially Potentiates Excitatory and Inhibitory Inputs to Spinal Lamina II Outer and Inner Neurons; J Neurophysiol, June 1, 2004; 91(6): 2413 - 2421. [Abstract] [Full Text] [PDF];

The term is derived from lumbar (lower spine), lamina (part of the spinal canal's bony roof), and -ectomy (removal). ... Laminectomy; After a retractor is used to pull aside fat and muscle, the lamina is exposed. Part of it is cut away to uncover the ligamentum flavum—a ligament that supports the spinal column.

The true spinal cord ends at approximately the L1 level, ... Laminae; The laminae are two flattened plates of bone extending medially from the pedicles to form the posterior wall of the vertebral foramen. The Pars Interarticularis is a special region of the lamina between the superior and inferior articular processes.

In conclusion, EGFP expression defined a substantial but, with respect to the measured parameters, rather inhomogeneous subgroup of GABAergic neurones in spinal lamina II. These results provide a base to elucidate the functional roles of this subgroup of GABAergic lamina II neurones, e.g. for nociception.

The normal anatomy of the spine is usually described by dividing up the spine into 3 major sections: the cervical, ... The lamina covers the spinal canal, the large hole in the center of the vertebra through which the spinal nerves pass. The spinous process is the bone you can feel when running your hands down your back.

Spinal lamina VI - Wikipedia, the free encyclopedia
Spinal lamina VI is a lamina of the spinal cord. It is also known as the base of the posterior horn.

Lee and Heckman, 2001 ). These issues remain relatively unexplored with regards to spinal lamina I. Therefore, using a combination of whole-cell recordings and computer simulations, we investigated the role of sodium and calcium currents in shaping EPSPs and the implications for signal processing by spinal lamina I neurons.
