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 .
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 ...
The dura mater is a sac that envelops the arachnoid mater and surrounds and supports the large dural sinuses carrying blood from the brain toward the heart. The dura has four areas of infolding: Falx cerebri, the largest, sickle-shaped; separates the cerebral hemispheres.
This bridge originates in the deep layers of the suboccipital muscles, specifically in the rectus capitis posterior minor muscle, and extends to join the dura mater of the cervical spinal cord. This structural connection forms a continuous link from the base of the skull to the top of the cervical spine. Recent studies postulate the existence ...
The spinal cord (and brain) are protected by three layers of tissue or membranes called meninges, that surround the canal. The dura mater is the outermost layer, and it forms a tough protective coating. Between the dura mater and the surrounding bone of the vertebrae is a space called the epidural space.
“Your brain only needs to coordinate one muscle group, so the pathways form faster,” says Rothstein. Complex, multi-joint movements, like a barbell snatch, might take months—or even years ...
After branching off the maxillary artery in the infratemporal fossa, it runs through the foramen spinosum to supply the dura mater (the outer meningeal layer) and the calvaria. The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior ...
Those who argued for the brain often contributed to the understanding of neuroanatomy as well. Herophilus and Erasistratus of Alexandria were perhaps the most influential with their studies involving dissecting human brains, affirming the distinction between the cerebrum and the cerebellum, and identifying the ventricles and the dura mater.
