Dura mater literally means "tough mother" that refers to a dense, inelastic, double- layered, vascularized membrane of the meninges that adheres to the inner surface of the skull.
The dura mater is a thick, fibrous membrane that covers the brain and spinal cord, and is one of the three layers of the meninges, the protective coverings that surround the central nervous system. In psychology, the dura mater may be relevant in the context of brain injury or neurological disorders affecting the central nervous system.
Examples of situations where the dura mater may be relevant include:
-
Traumatic brain injury: The dura mater can be damaged as a result of a traumatic brain injury, which can cause bleeding and swelling within the brain. This can lead to a variety of symptoms, including headaches, dizziness, and changes in consciousness.
-
Meningitis: Meningitis is an inflammation of the meninges, which can affect the dura mater. This can cause symptoms such as fever, headache, and stiff neck.
-
Intracranial pressure: Changes in intracranial pressure can affect the dura mater, which can lead to symptoms such as headaches and vision changes. In severe cases, increased intracranial pressure can cause herniation of the brain, which can be life-threatening.
-
Brain tumors: Brain tumors can grow within or around the dura mater, causing pressure on the brain and leading to symptoms such as headaches, seizures, and changes in behavior.
-
Spinal cord injury: Injuries to the spinal cord can also affect the dura mater, leading to symptoms such as paralysis, numbness, and changes in bowel or bladder function.
Overall, the dura mater is an important component of the meninges that protects the central nervous system. When it is damaged or affected by injury or disease, it can lead to a variety of neurological symptoms and conditions.
