Chapter 11 40-60

Front 1

Neuralgia

Back 1

sharp
pain
along
the
course
of
a
nerve

Front 2

Nociceptors

Back 2

sensory
receptors
sensitive
to
pain,
usually
free
nerve
endings

Front 3

Nonproliferative
retinopathy

Back 3

retinal
blood
vessels
are
damaged
(usually
over-­‐dilate,
form
aneurysms,
rupture,
photoreceptor
degeneration)
because
of
diabetes
mellitus

Front 4

Nystagmus

Back 4

an
involuntary,
persistent,
rapid
jerky
movement
of
the
eyes.
The
labyrinth
and
the
control
mechanism
for
eye
movement
are
very
tightly
connected.
When
the
labyrinth
(especially
the
semicircular
canals)
go
crazy,
nystagmus
is
present.

Front 5

Otitis
media

Back 5

infection
in
the
middle
ear.
Otitis—inflammation
or
infection
of
ear
structures.
Otitis
media
involves
the
middle
ear,
and
external
otitis
affects
the
external
ear.

Front 6

Otosclerosis

Back 6

a
metabolic
disease
of
the
inner
ear
that
most
commonly
affects
the
oval
window:
the
hole
in
the
labyrinth
that
holds
the
footplate
(bottom)
of
the
stapes.

Front 7

Ototoxic

Back 7

damaging
or
poisoning
of
the
ear,
usually
the
labyrinth

Front 8

Peripheral
neuropathy

Back 8

pain
arising
from
a
peripheral
nerve,
which
does
not
follow
a
dermatomal
distribution

Front 9

Phonophobia

Back 9

avoidance
of
sound
for
the
same
reason
as
light

Front 10

Phospholipase
A

Back 10

an
enzyme
that
produces
arachadonic
acid
(a
fatty
acid)
from
cell
membrane
lipids

Front 11

Photophobia

Back 11

avoidance
(fear
of)
light,
in
this
case
because
light
exposure
worsens
the
migraine

Front 12

Presbycusis

Back 12

hearing
loss
associated
with
aging.
It
is
usually
a
chronic
noise-­‐induced
loss.

Front 13

Presbyopia

Back 13

aging
vision,
a
form
of
hyperopia.
This
occurs
because
of
loss
of
ability
or
the
eye
to
undergo
accommodation
and
is
the
reason
we
older
folks
need
glasses
to
read.
Our
near
point
of
vision—the
point
at
which
objects
any
closer
to
the
eye
can’t
be
focused
upon,
causing
the
object
to
look
“blurry.”
Did
I
really
just
call
myself
“older?”

Front 14

Proliferative
retinopathy

Back 14

occurs
when
new
(abnormal)
blood
vessels
grow
in
the
retina.
The
new
blood
vessels
bleed
easily,
but
they
are
particularly
troublesome
because
they
cover
up
the
retina,
not
allowing
light
to
his
the
photoreceptors.

Front 15

Propped
bottles

Back 15

plug
the
baby
in
to
a
bottle
and
the
leaving
and
going
about
your
business.

Front 16

Prostaglandins

Back 16

produced
when
arachadonic
acid
is
modified
by
the
enzyme
cyclooxygenase

Front 17

Radiculopathy

Back 17

a
pattern
of
pain
perception
that
lies
within
a
particular
dermatome

Front 18

Refraction

Back 18

bending
or
changing
the
direction
of
a
ray
of
light,
necessary
to
focus
the
image
on
the
retina
(the
structure
in
the
back
of
the
eye
in
which
the
vision
receptors
[photoreceptors—
rods
&
cones]
are
located).

Front 19

Resorption

Back 19

the
destruction
or
dissolving
of
body
tissues,
in
this
case
the
bone
of
the
inner
ear

Front 20

Retinal
detachment

Back 20

occurs
when
the
retina
gets
torn
off
of
the
deeper
eye
layers
