Shedding Sheath Parietal

Sheath parietal: functions, structure and role

In human anatomy, the tunica parieta, also known as dura mater, is one of the three layers of the meninges. It is located intracranially and serves as a protective membrane for the brain and spinal cord. The tunica parietalis has important functions in maintaining the normal functioning of the nervous system and ensuring its structural integrity.

Structurally, the parietal membrane is a dense, durable and inflexible layer consisting of dense connective tissue. It surrounds and protects the brain and spinal cord, forming a kind of covering. The outer surface of the parietal shell is adjacent to the inner surface of the skull, and the inner surface is adjacent to the next shell, called the arachnoid.

The main role of the sheath parietal is to protect the nervous tissue from mechanical damage and environmental influences. It serves as a shock absorber, absorbing shock and reducing the possibility of brain damage from trauma and impact. In addition, the sheath parietal helps maintain the stability of the internal environment of the brain by regulating metabolism and ion levels around nerve cells.

Another important function of the parietal membrane is related to the circulation and drainage of cerebrospinal fluid. It contains a network of blood vessels that provide nutrition to the brain and spinal cord and remove waste and excess fluid from these organs. This is especially important for maintaining optimal conditions for the functioning of the nervous system.

Irregularities in the functioning of the parietal membrane can lead to various health problems. For example, damage or inflammation of this membrane can cause headaches, visual disturbances, seizures and other neurological symptoms. Some diseases, such as meningitis, can affect the shed parietal membrane, causing inflammation and dysfunction.

In conclusion, the tunica parietalis is an important structure that protects and maintains normal function of the brain and spinal cord. Its functions include protecting nervous tissue, maintaining the stability of the internal environment of the brain, and ensuring circulation and drainage of cerebrospinal fluid. If there is a problem with the shed parietal membrane, serious neurological symptoms can occur. Therefore, if you suspect a malfunction of this shell, it is important to consult a doctor for diagnosis and prescribing appropriate treatment.
