The cervical enlargement is a result of the increased volume of motor cells in the ventral horns of the grey matter. Here, motor neurons which innervate muscles of the upper limb are sited posteriorly in the anterior grey column, and those which supply the most distal muscles i.

The neck is part of a long flexible column, known as the spinal column or backbone, which extends through most of the body. The cervical spine neck region consists of seven bones C1-C7 vertebraewhich are separated from one another by intervertebral discs.

These discs allow the spine to move freely and act as shock absorbers during activity. Attached to the back of each vertebral body is an arch of bone that forms a continuous hollow longitudinal space, which runs the whole length of the back. This space, called the spinal canalis the area through which the spinal cord and nerve bundles pass.

The spinal cord is bathed in cerebrospinal fluid CSF and surrounded by three protective layers called the meninges duraarachnoidand pia mater. At each vertebral level, a pair of spinal nerves exit through small openings called foraminae one to the left and one to the right.

These nerves serve the muscles, skin and tissues of the body and thus provide sensation and movement to all parts of the body. The delicate spinal cord and nerves are further supported by strong muscles and ligaments that are attached to the vertebrae. Cervical stenosis occurs when the spinal canal narrows and compresses the spinal cord and is most frequently caused by aging. The discs in the spine that separate and cushion vertebrae may dry out and herniate.

As a result, the space between the vertebrae shrinks, and the discs lose their ability to act as shock absorbers.

At the same time, the bones and ligaments that make up the spine become less pliable and thicken. These changes result in a narrowing of the spinal canal. In addition, the degenerative changes associated with cervical stenosis can affect the vertebrae by contributing to the growth of bone spurs that compress the nerve roots.

Lumbar enlargement

Mild stenosis can be treated conservatively for extended periods of time, as long as the symptoms are restricted to neck pain. Severe stenosis requires referral to a neurosurgeon. Age, injury, poor posture or diseases such as arthritis can lead to degeneration of the bones or joints of the cervical spine, causing disc herniation or bone spurs to form. Sudden severe injury to the neck may also contribute to disc herniation, whiplashblood vessel destruction, vertebral bone or ligament injury and, in extreme cases, permanent paralysis.

Herniated discs or bone spurs may cause a narrowing of the spinal canal or the small openings through which spinal nerve roots exit. Neck pain may be caused by disc degeneration, narrowing of the spinal canal, arthritis and, in rare cases, cancer or meningitis.

We were very happy to find that all of our transportation was on time (mostly early) and comfortable. The guides were friendly and answered any questions that we had. They were very knowledgeable about the area of the tour. All of the needed paperwork was in order and we had no problem with any of the vouchers.
