Bundle Longitudinal Rear

Rear longitudinal beam (fasciculus longitudinalis dorsalis) is a bundle of nerve fibers that run along the posterior surface of the spinal cord. It is part of the posterior longitudinal fasciculus, which consists of several bundles of nerve fibers.

The posterior longitudinal fasciculus runs from the lower part of the medulla oblongata to the sacral spinal cord and serves to transmit sensory and motor signals to the posterior part of the body. It consists of two parts: the posterior bundle and the anterior bundle.

The posterior bundle consists of a large number of nerve fibers and runs along the posterior surface of the medulla oblongata and spinal cord, connecting them to the cerebellum and other parts of the brain. It is involved in transmitting sensory information from the skin and muscles to the brain, as well as in transmitting motor commands from the brain to the muscles.

The anterior bundle also consists of many nerve fibers and is located on the anterior surface of the medulla oblongata and spinal cord. It is responsible for transmitting motor commands to muscles and sensory information about body position and movements.

The posterior longitudinal fasciculus plays an important role in regulating body movements and providing sensitivity. It is also involved in the regulation of blood circulation and respiration. Disturbances in the functioning of the longitudinal posterior fasciculus can lead to various diseases, such as paralysis or sensory disturbances.

The longitudinal posterior bundle (lat. Fasciculus longitudinalus dorsalis) is a bundle of spinal nerve fibers that provide innervation to the muscles of the posterior part of the body, including the legs and buttocks. This structure is located in the lower part of the spinal cord and is one of the longitudinal fascicles of the spinal cord.

The longitudinal posterior fascicles are located in the broad fasciculus (Coffer's fasciculus), which connects the anterior and posterior spinal cords in the lower part of the spine. The longitudinal posterior bundles pass through the white matter of the spinal cord to their final point in the motor cortex, where they transmit signals to the muscles of the legs and buttocks.

The function of the longitudinal posterior bundle is to regulate the strength and movement of the muscles that control the motor activity of the legs and gluteal region. This bundle provides communication between the brain and the motor parts of the spinal cord, which allows you to control leg movements with the help of muscles and control motor activity. In addition, the posterior longitudinal fasciculus is responsible for regulating blood pressure and distributing blood throughout the body.

An important role of the longitudinal posterior bundle is its ability to ensure proper muscle function when walking, running and jumping. Impaired functionality of this bundle can lead to pain and even paralysis of the legs and limbs. In this regard, structural damage to this nerve requires timely diagnosis and treatment.

The main causes of posterior longitudinal fasciculus include systemic diseases such as multiple sclerosis, syringomyelia, viral infections, and alcohol or nicotine addiction. Also, the longitudinal bundle can be damaged after severe trauma or a tumor of the spine, when compression of the nerve bundle occurs.

Treatment for nerve defects includes medications, physical therapy, magnetic resonance imaging (MRI), and surgical techniques such as decompression and nerve grafting. Early diagnosis and treatment of the posterior longitudinal fasciculus are key factors to prevent undesirable consequences and improve the quality of life of patients.
