Subacute or chronic meningitis Acute bacterial meningitis is particularly serious and worsens rapidly. Most people with viral or noninfectious meningitis recover within a few weeks. Subacute meningitis and chronic meningitis usually progress slowly and gradually, but doctors may have difficulty determining what the cause is and thus what the treatment should be.

Jump to navigation Jump to search The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cordcontrolling movements of the limbs and trunk. The corticospinal tract is one of the pyramidal tractsthe other being the corticobulbar tract.

Anatomy[ edit ] The corticospinal tract originates in several parts of the brain, including not just the motor areas, but also the primary somatosensory cortex and premotor areas.

Then both tracts pass through the brain stem, from the pons and then to the medulla. The lateral corticospinal tract neurons cross the midline in the spinal cord, and controls the limbs and digits. However, connections to the somatosensory cortex suggest that the pyramidal tracts are also responsible for modulating sensory information from the body.

However, they can re-learn some crude, basic motions, just no fine movements.

Ependymoma brain tumors arise from a special type of cell in the central nervous system (CNS) known as the ependymal cells. Ependymomas were first discovered by Bailey in the year The nervous system consists of the brain, spinal cord, and nerves that connect the brain and spinal cord to the rest of the body (peripheral nerves).
