The spinal cord travels through the central canal formed by the vertebral foramina (singular: foramen), and the lumbar spinal nerves travel through the intervertebral foramina between adjacent vertebrae (Fig. Other prominent lumbar bony landmarks are the lamina, laminar groove, mammillary process, transverse process, facets, pars interarticularis, and vertebral body. If, on the other hand, the client’s lumbar curve is excessive, it is termed hyperlordotic the spinous processes of a hyperlordotic lumbar spine are more difficult to palpate.
However, some clients’ lumbar curves are decreased or even straight a decreased or absent lordotic curve is termed hypolordotic, making palpation of the spinous processes much easier. Because the lumbar curve is lordotic, the spinous processes are recessed and not as superficial for palpation as are the spinous processes of the thoracic spine. How easy or difficult it is to palpate the lumbar spinous processes depends largely on the degree of the client’s lordotic curve. However, these terms are also used to refer to the healthy and normal curve of the low back and neck.) All lumbar vertebrae have a spinous process that extends posteriorly and can usually be palpated. (The terms lordotic and lordosis are often used to denote an excessive and unhealthy lordotic curve.
