  2. Angiotensin-converting enzyme - Wikipedia

    Another more recent hypothesis is that higher levels of ACE can prevent Alzheimer's. It is assumed that ACE can degrade beta-amyloid in brain blood vessels and therefore help prevent the progression of the disease. [22] A negative correlation between the ACE1 D-allele frequency and the prevalence and mortality of COVID-19 has been established. [23]

  3. Dural venous sinuses - Wikipedia

    en.wikipedia.org/wiki/Dural_venous_sinuses

    The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous sinuses (channels) found between the periosteal and meningeal layers of dura mater in the brain. [1] [2] They receive blood from the cerebral veins, and cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations.

  4. Dura mater - Wikipedia

    en.wikipedia.org/wiki/Dura_mater

    The dura mater covering the spinal cord is known as the dural sac or thecal sac, and only has one layer (the meningeal layer) unlike cranial dura mater. The potential space between these two layers is known as the epidural space , [ 5 ] which can accumulate blood in the case of traumatic laceration to the meningeal arteries .

  5. Epidural space - Wikipedia

    en.wikipedia.org/wiki/Epidural_space

    In the skull, the periosteal layer of the dura mater adheres to the inner surface of the skull bones while the meningeal layer lays over the arachnoid mater. Between them is the epidural space . The two layers of the dura mater separate at several places, with the meningeal layer projecting deeper into the brain parenchyma forming fibrous septa ...

  6. Falx cerebri - Wikipedia

    en.wikipedia.org/wiki/Falx_cerebri

    The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.

  7. Subdural space - Wikipedia

    en.wikipedia.org/wiki/Subdural_space

    The subdural space (or subdural cavity) is a potential space that can be opened by the separation of the arachnoid mater from the dura mater as the result of trauma, pathologic process, or the absence of cerebrospinal fluid as seen in a cadaver.

  8. Meningeal lymphatic vessels - Wikipedia

    en.wikipedia.org/wiki/Meningeal_lymphatic_vessels

    To visualize the dura mater using immunohistochemistry, the dura must first be fixed within the skullcap. It is prepared by cutting around the base of the skull (inferior to the post-tympanic hook) and removing the lower portion of the skull and brain.

  9. Straight sinus - Wikipedia

    en.wikipedia.org/wiki/Straight_sinus

    The straight sinus is situated within the dura mater, where the falx cerebri meets the midline of tentorium cerebelli. [1] It forms from the confluence of the inferior sagittal sinus and the great cerebral vein. [1] [2] It may also drain blood from the superior cerebellar veins and veins from the falx cerebri. [1]
