Glossary of Terms---Page 2
Cerebral Cortex - The outer layer of the cerebrum.

Cerebral Hemisphere - One of the large, paired structures that together constitute the cerebrum of the brain.

Cerebral Spinal fluid (CSF) - Fluid that occupies the ventricles of the brain, subarachnoid space of the meninges, and the central canal of the spinal cord.Acts as a shock absorber for the brain.

Cerebrum - Portion of the brain that occupies the upper part of the cranial cavity.

Cerebrospinal Fluid (CSF) - The clear colorless fluid which bathes the surface of the brain and spinal cord.

Cervical - Pertaining to the area at the top of the neck where there are seven cervical vertebra. They are counted from top to bottom. At the top there is the first cervical vertebra often referred to as C1, then the second C2 than C3,C4,C5,C6, and C7.

Charcot Joint - A type of diseased joint associated with varied conditions; syringomyelia among them, which involves disease or injury to the spinal cord. It is characterized by hypermobility. Decalcification of bone on joint surfaces occurs accompanied by overgrowth of bone. This results in deformity and instability of the joint. Pain is uncharacteristic, but may occur.

Chiari Malformation - condition where the cerebellar tonsils are displaced out of the skull area into the spinal area, causing compression of brain tissue and disruption of CSF flow

Chiari II - more severe form of malformation which involves descent of parts of the brainstem and is usually associated with Spina Bifida

Chronic - Long lasting; a disease having a long course; not acute.

CINE MRI - type of "motion picture" MRI which can show CSF flow ...originally developed for heart related testing

Cisterna Magnum - A cavity, a dilation of the subarachnoid space which is located between the cerebellum and the medulla. It receives CSF from the fourth ventricle via the medial foramen of Magendie.

Clonus - A series of alternating muscle contractions and partial relaxations that produce a convulsive spasm.

CM - Chiari malformation.

Color Doppler Ultrasound (CDU) - type of ultrasound which can detect flow of blood and CSF... can be used during surgery for more accurate evaluation of improvements in CSF flow

Congenital - Existing at birth; usually refers to certain mental or physical traits, peculiarities, or diseases; is a more general term than hereditary since congenital includes conditions due to influences arising during gestation.

Cranial Nerve - Nerve that arises from the brain .

Craniectomy - The excision (removal) of part of the skull

Craniocervical Junction - the area where the skull and spine meet

CT Scan - A specialized X-ray that takes images around the body that are reconstructed by a computer to give a more detailed image than a standard x-ray.

Dandy Walker - A syndrome characterized by hydrocephalus in infants associated with an abnormal closure of the passage at the foramina of Luschka and Magendie.

Decompression - To take pressure off, relieve pressure.

Doplopia - symptom of seeing double, or double vision

Dura - The outermost, toughest and most fibrous of the three membranes covering the brain and spinal cord.

Dura Mater - Tough outer layer of the membranes surrounding the brain and spinal cord.

Duraplasty - a surgical technique where a patch is sewn into the dura to allow for more room for the brain
