Central Channel

The central canal is one of the main elements of the spinal canal, which passes through the human spine. It is a central canal because it runs through the center of the spinal cord, which is the human central nervous system.

The central canal is approximately 45 cm long and consists of a dura mater and a central canal. The dura mater is made up of several layers of tissue that protect the spinal cord from damage. The central canal is a narrow canal that contains the spinal cord and its vessels.

The functions of the central canal include transmitting nerve impulses from the brain to the spinal cord and back. In addition, the central canal also provides nutrition to the spinal cord and protects it from damage.

In medicine, the central canal can be damaged by various diseases such as tumors, infections and injuries. In such cases, treatment is required, which may include surgery, radiation therapy, or drug therapy.

The importance of the central channel for human health cannot be overestimated. It plays a key role in transmitting nerve impulses and providing nutrition to the spinal cord. Therefore, it is necessary to monitor the health of this important element of the spinal canal and take measures to protect it from damage and disease.

central canal *(canalis centralis; syn. mesencephalon)* - a canal in the midbrain that has a tubular structure; through a funnel connects the third and fourth ventricles. It contains the central pathway of the visual analyzer, which connects to the subthalamic nucleus, the medial part of the nucleus of the digastric nerve - the red nucleus, the central gray matter and the tent nuclei. Receives a large portion of all ascending tegmental nuclei of the midbrain and hindbrain through the cerebral aqueduct, superior cerebellar peduncles, and roof of the corpus callosum. The nuclei of the inferior medullary velum receive only fibers from the lateral longitudinal fasciculi from the central canal. The fibers of the vestibular afferent tract intersect in the canal (their opposite sides are skewed), and in the lateral walls there are coordinate bundles of the VI pair of cranial nerves (vertebral column). It continues into the cerebral hemisphere onto the anterior surface of the pons, then into the brain stem and then joins the medulla oblongata, crossing it at the level of the upper end of the pons.
