Horn of the Spinal Cord Anterior

The anterior horn of the spinal cord (cornu anterius medullae spinalis) is one of the two horns of the spinal cord, which is located on the anterior part of the spinal cord. It is cone-shaped and is part of the spinal cord of the central nervous system.

The posterior horn of the spinal cord (cornu posterius medullae spinalis), also known as the cornum, is the second horn of the spinal cord and is located at the back of the spinal cord. Cornum is responsible for controlling the muscles located in the back of the body, such as the legs, arms and back.

The anterior horn of the spinal cord is closely connected to the cerebellum and brain. It contains nerve cells that transmit signals from the cerebellum to the spinal cord and back. This allows the brain to control body movements and provide coordination.

In addition, the anterior horn of the spinal cord is involved in the regulation of metabolism and the body's immune system. It also controls hormone levels and other physiological processes.

It is important to note that the anterior horn of the spinal cord is an important part of the nervous system and its dysfunction can lead to serious health problems. Therefore, if you have any symptoms associated with this horn, it is necessary to see a doctor for diagnosis and treatment.

In conclusion, the anterior horn of the spinal cord plays an important role in motor coordination, metabolic control, and other physiological processes. Its dysfunction can lead to serious illnesses, so it is important to monitor your health and consult a doctor if symptoms appear.



The forebrain horn (lat. Cornu anteríus medulláe spinalís, PNA, BNA) is one of twelve paired horns of the spinal cord. Supplies muscles with blood.

The forebrain horn of the spinal cord is a horny outgrowth of the hindbrain at the site of transition of the pons (mesocephalic part) to the medulla oblongata (neurocephalic). It is an appendage of the hindbrain in the form of a flat asymmetrical circle with a relatively large anterior end. Its posterior section passes into the commissure of the cerebellum with the bodies of the posterior horns. From the lateral surface of the spinal nerve roots downwards and in front, this appendage is covered with the remains of the pia mater, on which the periarticular venous plexuses are located. It consists of gray matter, which is divided into 7 segments, each of which has an anterior part and a posterior part. The anterior part of each segment contains the axons of the neurons of the spinal ganglia of the spinal cord segment of the same name, and the posterior part contains the pyramidal tract from the central canal of the spinal cord of the underlying segment, the caudal cord of the white matter of the spinal cord and the fibers of the pontine nerve. Axons of fibers of one segment cross each other in this area, forming a network that contains several thousand neurons. Fibers from each anterior segment are directed to the thalamus, then to the limbic system, including the hypothalamus. Depending on whether the segment is sensory or motor, the fibers will contain inhibitory neurons (in the anterior segment parasyphilis) or descending motor fibers to the skeletal muscles (in the posterior segment myasthenia gravis), respectively. The transfer of information between the layers of cells in the horns of the spinal cord is carried out through the “gray matter-smooth muscle” structure, which is also found in the horns of the brain.

Diseases and pathologies associated with the horns of the spinal cord: * Hydrocephalus of the anterior horn of the spinal cord is a congenital anomaly of brain development associated with difficulty moving cerebrospinal fluid. This leads to a decrease in the volume of the ventricles of the brain and accumulation of cerebrospinal fluid near the choroid plexuses of the lateral ventricles. With hydrocephalus of the anterior horn, swelling is observed in the area of ​​the frontal and parietal lobes of the brain. * Glioma of the anterior horns of the spinal canals of the brain can arise as a result of a mutation in the structural gene and the accompanying gene (SF3B1), associated with their involvement in certain tumors of the thyroid gland and gastrointestinal tract (stomach, duodenum). Choroidal liver cell cancer is also related to this gene. * Myelography of the spinal bladder and brain stem is performed infrequently, but it is very useful in the diagnosis of brain tumors and shows their relationship with the brain, which is useful for planning stereotactic radiosurgery or radiation therapy.



The anterior horn of the spinal cord is an anatomical structure, part of the spinal canal from which the first lateral bundle of 7 roots located in front of the spinal cord departs. The anterior branch of this branch runs parallel to the anterior surface of the spinal cord and has three branches, one of which is the yellow arcuate knee. These are important structures in spine surgery and lumbar spine surgery.
