Neoplasm
[ neo- +Greek
plasma, thing formed] New growth;
an abnormal tissue that grows by cellular
proliferation more rapidly than normal
and continues to grow after the stimuli
that initiated the new growth cease.
The term tumor, which literally means
swelling, is frequently used synonymously
with the word neoplasm.

Nerves:
Bundles of fibers
(outside the brain and spinal cord). |
| Nerve
Entrapment: A
region of mechanical neuritis in which
the nerve is maintained in an irritated
state by external pressure created by
encroachment or impingement from a nearby
anatomical structure; for example, pressure
on the median nerve by swollen tendons
and their sheaths in the carpal tunnel
lead to the carpal tunnel syndrome.
|
| Nerve
Tracts:
Nerve cell bodies of functionally related
neurons tend to mass together, and their
fibers, if long, tend to run parallel
to one another in bundles. Within the
cord such bundles are called tracts. |
| Neuritis:
Inflammation of a nerve, marked by neuralgia
(nerve pain), hyperesthesia (hypersensitivity),
anesthesia (numbness), or parasthesia
(undefined pain), paralysis or muscular
astrophy in the region supplied by the
affected nerve. |
| Neuroma:
[ neuro- nerve oma,
tumor] A general term for any neoplasm
(growth) derived from cells of the nervous
system. |
Neurolysis:
Freeing of nerve
from inflammatory adhesions. |
| Neuropathy:
[neuro+ Greek
pathos, suffering] Any disease
of the nervous system. |

Peripheral
nervous system:
All the nerves
that come out from the brain and spinal
cord, extending to receive sensory
stimulus from the skin, comprise the
peripheral nervous system. |
| Plexus:
When adjacent
nerves exchange bundles of fibers, weaving
a web or network of communicating nerve
fibres. |
| S |
|
| Schwann
cell:
Also
called a neurolemma cell, present on
all peripheral nerves and responsible
for many functions including the promotion
of nerve regeneration following injury
to the nerve. |
Schwann
cell
sheath (neurolemma
sheath): The
sheath surrounding the nerve fibre. |
