glia ( The tissue that forms the support element of cells and fibers of the
nervous system).
Gliosis: Proliferation or growth by reproduction of the
neuroglial tissue in the central nervous system.
Greenstick Fracture: A fracture (bone break) in which
the bone is bent but broken only on the outside of the bend.
Gyrus: One of the convolutions of the cerebral
hemispheres of the brain. The upraised ridges at the cerebrum.
Hemiplegia: Paralysis or severe weakness (paresis) of
one side of the body, caused due to injury or disease of the brain or spinal
cord.
Hemivertebrae: A congenital absence of half of a
vertebra.
Horner Syndrome: An abnormal condition with contraction
of the pupil, partial drooping of the eyelid, recession of eyeball back into
socket, and sometimes loss of sweating over the affected side of the face,
due to paralysis of the cervical sympathetic nerve trunk.
Hydro: Water, or collection of fluid containing water.
Hydrocephalus: An increased accumulation of CSF within
the ventricles of the brain, caused due to interference with normal
circulation and with absorption of the fluid, especially from destruction of
the formation of the foramina of Magendie and Lushka. This condition may
also result from developmental anomalies, infection, injury, or brain
tumors.
Hydromyelia: Fluid accumulation in the enlarged central
canal of the spinal cord.
Hyper: Excessive, or beyond.
Hyperreflexia: Overactive neurological reflexes.
Hypo: Less than, below, or under.
Hypoplasia: Defective development of tissue.
Hyporeflexia: A condition caused due to decrease in the
action of the reflexes.
Hypotonia: Loss of muscle tone resulting in reduced
tension by relaxation of arteries.
ICP: Intercranial pressure.
Idiopathic: Pertaining to conditions without clear
cause, as of spontaneous origins.
Impulse: A wave of depolarization transmitted along a
nerve fiber or muscle fiber.
Increased Intracranial Pressure (ICP): An increase in CSF production or
blockage resulting in pressure on the brain. The skull cannot expand to
accommodate the pressure which leads to symptoms.
Inferior: Situated below the surface or part.
Insidious: A disease marked by a lack of symptoms. In
such diseases patient is unaware of the onset of the disease.
Interpedicular Spaces: Space between the pedicles of
the vertebrae.
Invasive Procedures: A medical procedure that requires
entrance into the body as part of the action required.
Ipsilateral: On the same side or affecting the same
side of the body. Associated with (paralysis) appearing on the same side of
the body as the brain or spinal cord lesion producing them.
Ischemia: Deficiency of blood in a part of the body.
Klippel Feil Syndrome: Congenital anomaly characterized
by a short wide neck, low hairline, reduction in the number of cervical
vertebrae, and fusion of the cervical spine.
Kyphosis: Abnormal curvature of the spine resulting in
condition commonly known as hunchback.
Laminectomy: The removal of the posterior arch of a
vertebra by surgical procedure.
Larynx: Structure located between the trachea and
pharynx, which houses the vocal cords.
Lateral: Relating to any particular side of the body.
Lumbar: The lower portion of the spine that comprises
of 5 vertebrae.
Magnetic Resonance Imagery (MRI): A scanner that uses
magnetic energy to give a clear black and white picture of the brain and
cervical canal.
Medial: Toward the middle of the body.
Medulla Oblongata: Portion of the brain stem located
between the pons and the spinal cord.
Meninges: A group of three membranes which covers the
brain and spinal cord.
Meningitis: Infection or swelling of the membrane
(meninges).
Meningo: Relates to the meninges, membranes covering
the brain and spinal cord.
Mesencephalon: The midbrain, one of three primitive
cerebral sacs that has been base for development of the copora quadrigemina,
the crura cerebri, and the aqueduct of Sylvius.
Microgyri: The smallest cerebral convolutions.
Morvans Chorea type: A condition with irregular and
uncontrollable movements.
Myelo: Pertaining to the spinal cord.
Myelodysplasia: Defective formation of the spinal cord.
Myelogram: X-ray inspection of the spinal cord by
utilizing radiopaque medium, which is injected into the intrathecal space
(area within the spinal cord) of the spine.
Myelomeningocele: Form of spina bifida in which
portions of the spinal cord and its membranes protrude through the opening
in the vertebral column.
Myelotomy: Surgical severing of nerve fibers of the
spinal cord.
Necrosis: Death of areas of tissue surrounded by
healthy parts that connects the brain and the spinal cord with other parts
of the body.
Neurovascular Bundle: Structure comprising of a group
of nervous and blood vessel tissues.
Nissen Fundoplication: Asurgical procedure to treat
gastroesophageal reflux disease (GERD) and hiatus hernia.
