Nervous System
Dr.Hannah


The nervous system is a very
complex system in the body.
The nervous system is the body's
information gatherer, storage
center and control system.

and is often likened to the central
computer within a vast,
complicated communication
network
Its divided into two parts
 Central nervous system (CNS)
 Peripheral nervous system (PNS)

 CNS:
consists of the brain
and the spinal cord
 PNS:
includes the nerves
that carry messages to and
from the brain and spinal
cord




Alzheimer disease: deterioration of
mental capacity-which can lead to
dementia.
Cerebrovascular accident: damage of the
blood vessels supplying brain-stroke
Concussion: Blunt injury to the brain
which causes loss of consciousness



Epilepsy: chronic brain disorder
characterized by recurrent seizure
activity
Glioblastoma: brain tumour from glial
cells
Hemiplegia: plegia-paralysis, hemione half. Usually result of stroke



Meningitis: Inflammation of the
meninges
Multiple sclerosis: destruction of myelin
sheath on nerve cells in central nervous
system
Paraplegia: paralysis affecting lower part
of the body. Plegia-paralysis, para-one
side

Syncope: fainting; inadequate
blood supply to the brain. (NOT
the loss of the blood supply like
in a stroke)

Cerebral angiography: X-Ray of the
brain + contrast in the artery.

Computed Tomography (CT) scan: cross
sectional X-Ray. Good for detecting of
haemorrhage in a brain cavity
Lab and Diagnostic
procedures
•Electroencephalography: recording of
electrical activity within the brain
Lumbar Puncture (LP): spinal tap
procedure by which CSF is removed.

Cerebrospinal fluid analysis: blood
cells, glucose, cultures, Gram stain,
chemical composition. Obtained
through Lumbar Puncture (LP)


Magnetic resonance imagine (MRI): magnetic
waves and radiofrequency are used to create
images

Positron emission tomography (PET) scan:
uptake of radiographic material into the brain
shows how the brain uses glucose and gives
info on how the brain functions
