Vestibular Sense
System located in the inner ear that allows us to make
adjustments to bodily movements and postures.
Disorders of this sense can cause extreme dizziness or
disorientation.
Tells us how our bodies are postured and when we are
moving.
Utricles
Fluid filled chamber in the
inner ear that detects changes
in gravity.
Head movement activates
vestibular system
Orienting ourselves to the
environment.
Semicircular Canals
Fluid filled passages in
the inner ear that detect
movement of the head.
Movement causes hair
cells to bend, sending
information to the brain.
Saccule
A bed of sensory cells
situated in the inner ear.
Translates head
movements into neural
impulses which the brain
can interpret.
Kinesthetic Sense
System of receptors located in the muscles and
joints that provides information about the
location of the extremities.
Sense receptors located in the joints and
muscles send information to the brain
concerning muscle tension and joint
perception: determine location of limbs.
Receptors connect to processing regions in the
parietal lobe.
Highly involved in skilled activity, such as
sports.
Phantom Limb Sensation
The sensation that an
amputated or missing limb
is still attached to the body
and is in moving in
accordance with the other
limbs.
People with this condition
also feel sensations from
the missing limb, usually
painful.
Cutaneous Sense
System of receptors
located in the skin that
provides information
about touch, pressure,
pain and temperature.
Pain: harmful stimulusheat/cold, chemicals,
break or invasion of
skin.
Receptors
A receptor is a free nerve
ending.
Mechanoreceptors:
touch/pressure
Thermoreceptors:
temperature
Nocioreceptors: pain
Cutaneous receptors:
receptors on the skin that
provide sensory
information.
Gate Control Theory
Theory of pain stating
that the release of
substance P in the spinal
cord produces the
sensation of pain.
Endorphins block the
release of substance P.
(i.e. “Runner’s High”)
Acupuncture
Endorphins are responsible for
the pain-relieving effects of
acupuncture.
Acupuncture is an alternative
medicine methodology
originating in ancient China that
treats patients by manipulating
thin, solid needles that have been
inserted into acupuncture points
in the skin
Lamaze Method
A method that prepares a
mother for natural
childbirth; the pregnant
woman (in classes and at
home) practices (usually
with the help of a coach) and
learns about the physiology
of childbirth and techniques
of relaxation, concentration,
and breathing.
Congenital Analgesia
One or more
conditions where
a person cannot
feel and has never
felt physical pain.
