INTRODUCTION TO THE
SENSORY SYSTEM
THE SENSE OF SIGHT
THE SENSE OF HEARING
THE SENSE OF SMELL AND
TASTE
THE SENSE OF TOUCH
SENSORY INPUT

3. SENSORY
SYSTEM
The sensory system encompasses the
body's ability to perceive and respond to
stimuli from the environment. It includes
the senses of sight, hearing, smell, taste,
and touch. Each sense plays a crucial role
in how we experience the world around us.

4. SENSORY
SYSTEM
All information we receive from
the world around us comes to us
through organs that are
responsible for our five senses

5. Parts of the Eye
EYES & SENSE OF SIGHT
Cornea
Sclera
Conjunctiva
Iris
Pupil
Lens
Retina
Macula
Fovea
Optic Nerve
Age related Changes in Vision
The most common changes in
the eye as the person ages is
the condition called
PRESBYOPIA. The lense loses its
elasticity and ability to focus
rapidly and clearly, particularly
to the object close to the eye
Diseases of the Eye
The identifiable
and common
diseases of the
Eye are
Cataracts and
Glaucoma

6. Parts of the Ear
EARS & SENSE OF HEARING
Outer Ear
Eardrum
Middle Ear
Inner Ear
Age related Changes in Hearing
The most common changes in
the ear as the person ages is
the condition called
PRESBYCUSIS. This results in
ability to hear high-pitched
sounds. The person with
PRESBYCUSIS may hear sound of
a conversation, but unable to
understand the tone of the
words
Age related Changes in Hearing
Another hearing problem among
the older residents is TINNITUS,
a continual ringing, roaring, or
hissing sound in the ears.

7. Function
NOSE & SENSE OF SMELL
Age related Changes in Smell
The sense of smell declines with
age. Many people have difficulty
identifying common odors.
Since the sense of smell is
important, this can contribute
to a loss of appetite.
The special lining of the
upper part of the nose
enables us to smell and
detect differences in
odors.

8. Function
TONGUE & SENSE OF TASTE
The tongue is the
organ for the
sense of taste.
Tiny buds on the
tongue allows us
to tell the
difference among
sweet, sour,
salty, and bitter
taste
Age related Changes in Taste
As the number of buds decrease
as a person ages. The tastes for
sweet and salty seems to
decline first, causing the older
person to increase the use of
salt and sugar. The loss of taste
often a loss of appetite

9. Function
SKIN & SENSE OF TOUCH
The skin is the organ for
sense of touch. Special
sensory nerve cells send
different messages about
touch to the brain. These
nerve cells can Identify
pressure, pain, heat and cold
Age related Changes in Taste
The special nerve cells
lose some of their
sensitivity as a person
ages. The older person
may not experience
normal levels of pain or
accurately perceive hot
and cold.
DIseases affecting the sense
of touch
There are some disease
which can affect the older
person’s sense of touch.
RHEUMATOID ARTHRITIS
cause deformities in
hands, making it difficult
and painful for the person
to handle and touch
things.

10. SENSORY INPUT
Age and disease affects all five of the sense, this result
in less information being sent to the brain about the
environment. If the loss is severe, the person can
become confused and angry, as well as have difficulty
with the activities of daily living
