Horn of the Spinal Cord Posterior

The horn of the spinal cord, Posterior, is an elongated formation (a modification of the nerve root), which is located outward from the posterior surface of the spinal segment. Anterior to the posterior horn is the anterior cutaneous nerve of the thigh or the common iliac artery and vein. These vessels pass through a large amount of loose tissue and are often compressed or the painful posterior root syndrome they bring is usually called anterior embryonic ring syndrome. Thus, the cause of the syndrome may be the pressure of the growing internal iliac artery on the nerve elements forming the anterior root. In this case, the posterior root is deformed - at the exit from the intervertebral foramen, a zone of circular shortening of the nerve trunk appears, which is usually accompanied by compression.

Horn of the spinal cord Posterior

The posterior horn of the spinal conus is part of the medial base of the brain and is located in the posterior part of the transverse foramen of the conical cushion. Its important anatomical structure is the dorsal root.

Structurally, the posterior horn of the spinal conus is characterized by the presence of posterior (dorsal), middle (ventral) and anterior (lateral) surfaces. The surfaces have special designations depending on their location on the brain stem. In particular, the posterior horn is characterized by the presence of an external arcuate field and a posterior arcuate field. Between them lies the fibrous ectoderm and

The anterior and posterior horns of the spinal cord, the root horns (lat. cornua dorsalia medullaris), are small formations located on the spinal roots that help strengthen muscles, tendons and joints. Antlers lengthen muscles and joints, while joints become stronger due to the fact that the formation of horns strengthens the ligaments of the joints. Unlike the anterior horns, the posterior horns are formed differently: here there is not lengthening, but shortening of the muscles and ligaments of the joints due to the fact that the processes of their muscle cells fall under the fascial bag or the connection of individual fasciae. The muscle cells then adapt to the joint, providing stability and stability. During load - physical activity - tendons, muscles and joints are displaced, while the joint is able to move and function correctly, but without sudden movements. During repair, tension is created in the fascia, which forms a horn, which provides increased strength and makes the fascia stiffer. Thus, under any load, the joints remain protected from damage.

The posterior horn can form only in cases where the mobility of the bone joints is limited. In other words, most often the posterior horn can form in the joints of the cervical, thoracic and lumbar parts of the spine. The cervical region has such a large lever that additional strengthening formations there may rarely be required. In the chest and belt
