The dura mater (Dura, Aura Mater, Pachymeninx) is the outer and thickest of the three meninges, which surrounds the brain and spinal cord. Its name "solid" refers to its dense structure, which provides additional protection to the brain.
The dura mater consists of two plates: outer and inner. The outer plate is also the periosteum of the skull. This means that the dura mater is in direct contact with and attached to the bones of the skull.
However, in some places the dura mater splits, and its inner layer passes down and extends deeply in the form of processes into the cracks that separate parts of the brain from each other. For example, between the hemispheres of the cerebrum there passes the falx cerebri, which between the hemispheres of the cerebellum forms the falx cerebellum (falx cerebri), and between the cerebellum and the cerebrum - the tentorium cerebellum (tentorium). These projections help keep the brain in the correct position and prevent it from moving.
The inner layer of the dura mater is separated from the arachnoid mater by a thin film of fluid that is not cerebrospinal fluid. This fluid serves to lubricate the brain and reduce friction between its surface and the inner surface of the dura mater.
The dura mater is important for protecting the brain. It provides mechanical support to the brain and protects it from damage that may occur from impacts and other trauma. Also, the dura mater helps maintain a constant internal environment of the brain, protecting it from external factors.
In conclusion, it is worth noting that the dura mater is an important component of brain protection and plays a key role in ensuring normal brain function.
The dura mater, also known as Dura Mater, Aura Mater or Pachymeninx, is the outer and thickest of the three meninges surrounding the brain and spinal cord. The word "Dura" comes from the Latin term meaning "hard", reflecting its dense and durable structure.
The dura mater consists of two plates: outer and inner. The outer plate is also the periosteum of the skull, providing additional protection for the brain. The internal lamina also plays an important role in maintaining the structure and protection of the brain.
A special feature of the Dura mater is its ability to split and penetrate into various crevices between different parts of the brain. In some places, the inner layer of the membrane passes down and enters deeply into the brain in the form of processes. Such processes separate and separate different parts of the brain. For example, between the hemispheres of the cerebrum there passes the falx cerebri, which between the hemispheres of the cerebellum forms the falx cerebri (falx cerebri). There is also a tentorium (tentorium), which separates the cerebellum and the cerebrum.
The inner layer of the dura mater is separated by a thin film of fluid, but not cerebrospinal fluid, from the arachnoid membrane of the brain. This film of fluid, known as the paraxial film, serves to cushion and absorb possible shock and damage that may result from head or body movements.
The dura mater performs several important functions. First, it serves as a protective barrier for the brain and spinal cord, preventing damage from external influences. Second, it helps maintain the structure of the brain and spinal cord by giving them their shape and maintaining their position within the cranial cavity. In addition, the Dura mater contains vessels and blood vessels that provide nutrition to the brain and spinal cord.
In conclusion, the Dura mater is an important component of the central nervous system's defense system. Its thick and durable structure provides reliable protection for the brain and spinal cord, maintaining their integrity and functionality. Thus, the dura mater is an integral part of the anatomy and physiology of our nervous system.
The lining of the brain is important for the proper functioning of the brain. It is the outer thickest of the three meninges. She is also called Dura Mater, which means “powerful mother”.
The outer layer is the periosteum of the skull, called the pachymene. The inner layer is called adventitia. Both layers of the dura mater consist of collagen fibers and connective tissue. The membrane contains blood vessels and fibers of the arachnoid layer.
The main functions of the dura mater: - Supportive function - it supports the brain and spinal cord, preventing their damage. - Protective function - protects the brain from injury, infections and other external influences. - Regulatory function - ensures normal blood circulation in the brain and protection from
