What medical term means congenital herniation of the meninges?
Meningoencephalocele – A protrusion of both the meninges and brain tissue through a skull defect; one form of spina bifida.
Is the congenital herniation of the meninges through a defect in the skull or spinal column group of answer choices?
Meningocele: A type of spina bifida characterized by herniation of the meninges through a spine defect, forming a cyst filled with cerebrospinal fluid.
What term means congenital herniation of brain tissue through a gap in the skull?
Encephaloceles are rare birth defects associated with skull defects characterized by partial lacking of bone fusion leaving a gap through which a portion of the brain sticks out (protrudes). In some cases, cerebrospinal fluid or the membranes that cover the brain (meninges) may also protrude through this gap.
What process is used to record the electrical activity of the brain through the use of electrodes attached to the scalp?
An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp.

What are the meninges?
Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain. The tough outer layer is called the dura mater.
How the meninges and cerebral fluid help protect the brain?
The meninges help to anchor the CNS in place to keep, for example, the brain from moving around within the skull. They also contain cerebrospinal fluid (CSF), which acts as a cushion for the brain and provides a solution in which the brain is suspended, allowing it to preserve its shape.
What is the CF that refers to Neuroglial tissue?
glue; neuroglial tissue. (CF) glioma. tumor (composed of) neuroglial tissue.
What is the instrument used for EEG?
In 1929 German scientist Hans Berger published the results of the first study to employ an electroencephalograph, an instrument that measures and records these brain-wave patterns. The recording produced by such an instrument is called an electroencephalogram, commonly abbreviated EEG.
How is EEG used to study the brain?
An EEG records the electrical activity of the brain via electrodes affixed to the scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders.
What are diseases that are related to the brain and spinal cord?
Infections, such as meningitis, encephalitis, polio, and epidural abscess. Structural disorders, such as brain or spinal cord injury, Bell’s palsy, cervical spondylosis, carpal tunnel syndrome, brain or spinal cord tumors, peripheral neuropathy, and Guillain-Barré syndrome.
What are the meninges of the spinal cord?
Meninges are connective tissue layers surrounding the brain, the spinal cord, and the roots of peripheral nerves. The pia mater (P) is a delicate connective tissue layer attached directly to the white matter of the spinal cord. The dura mater (D) is a thick connective tissue layer.
What is spontaneous herniation of the spinal cord?
Herniation of the spinal cord, or displacement of the cord outside the dura, is so rare that only 13 cases have been reported in the literature. The authors report a new case of spontaneous herniation of the spinal cord in a 38-year-old man who presented with lower left limb paresis and Brown-Séquard syndrome, with a T-8 sensory level.
What are the types of herniation of the spinal cord?
Based on a review of the literature, herniation of the spinal cord may be classified as spontaneous, iatrogenic, or traumatic. At cervical levels, the spinal cord has herniated into an iatrogenic pseudomeningocele located dorsally.
When is surgery indicated in the treatment of spinal cord herniation?
Surgery is generally recommended for patients with motor function deficit or progressive neurological symptoms. [ 42, 63, 81] Surgical treatment aims to reduce the spinal cord herniation and prevent recurrence.
