- Meninges. There are three layers of meninges around the brain and spinal cord. The outer layer, the dura mater, is tough, white fibrous connective tissue. The middle layer of meninges is arachnoid, a thin layer resembling a cobweb with numerous threadlike strands attaching it to the innermost layer.

- The meninges are three layers of protective tissue called the dura mater, arachnoid mater, and pia mater that surround the neuraxis. The meninges of the brain and spinal cord are continuous, being linked through the magnum foramen. Dura Mater The dura mater is the most superior of the meningeal layers.Its name means hard mother in Latin and it is tough and inflexible. This tissue forms several structures that separate the cranial cavity into compartments and protect the brain from displacement. The falx cerebri separates the hemispheres of the cerebrum.he dura mater is the most superior of the meningeal layers. Its name means hard mother in Latin and it is tough and inflexible.

brain The cerebellum is the hind part of the brain. It is made up of gray, unmyelinated cells on the exterior and white, myelinated cells in the interior. The cerebellum coordinates muscular movements and, along with the midbrain, monitors posture. It is essential to the control of movement of the human body in space.

The Hindbrain: Myelencephalon & Metencephalon The metencephalon. 1  Pons – The part of the metencephalon located on the brain stem that forms a bulge on the brain stem’s ventral surface. 2  Cerebellum – The “cauliflower” piece in the back of the brain that is responsible for sensorimotor function (the part that helps regulate posture, balance, and coordination). Think of the “practice makes perfect” theory of sports, for example.

Anatomy of the Brain: The Meninges The meninges are the coverings of the brain. They protect the brain by housing a fluid-filled space, and they function as a framework for blood vessels. The meninges have three layers: the dura mater, the arachnoid mater, and the pia mater. The arachnoid mater is attached to the pia mater by arachnoid trabeculae, which is a weblike matrix of connective tissue. The space between the two layers, the subarachnoid space, is filled with cerebrospinal fluid (CSF).

- The human cerebral cortex is very deeply wrinkled, so it has a lot of grey matter, which has the large majority of all the neurons in the CNS. In Figure 5-2d, sulci (singular = sulcus) are shown by the curving lines on the cerebral hemispheres. The ridges between the sulci are the gyri (singular = gyrus).

Chapter 41: The spinal cord and meninges The spinal cord, like the brain, is surrounded by the three meninges. The dura mater extends from the foramen magnum to the sacrum and coccyx (see fig. 41-1). The dura is attached to the foramen magnum and the periosteium covering the uppemost cervical vertebrae and their ligaments.

The delicate innermost layer of the meninges — a thin fibrous tissue that is impermeable to fluid which allows it to enclose CSF (cerebrospinal fluid). By containing CSF, pia works with the other meningeal layers to protect and cushion the brain.

There are three layers of tissue in the meninges: the pia mater, the arachnoid mater, and the dura mater. The pia mater (the name means tender mother) lies closest to the brain and the spinal cord.

Patterns of Contrast Enhancement in the Brain and Meninges Extraaxial enhancement in the CNS may be classified as either pachymeningeal or leptomeningeal. The pachymeninges (thick meninges) are the dura mater, which comprises two fused membranes derived from the embryonic meninx primativa: the periosteum of the inner table of the skull and a meningeal layer.

Meningioma Posterior fossa / petrous meningioma forms on the underside of the brain and accounts for approximately 10 percent of meningiomas. It can press on the cranial nerves, causing facial and hearing problems. Petrous meningiomas can press on the trigeminal nerve, causing a condition called trigeminal neuralgia.

- At the rear of the brain is the cerebellum. The cerebellum is similar to the cerebrum in that each has hemispheres that control the opposite side of the body and are covered by gray matter and surface folds. The vermis, which is a central constricted area, connects the hemispheres.
