2. • GENERAL OBJECTIVE
At the end of the topic students will be able to get depth knowledge
regarding “Sensory Process – Normal and Abnormal”.

3. • SPECIFIC OBJECTIVE
At the end of the topic students will be able to,
1. Introduction of normal and abnormal sensation.
2. Types of sensation.
 Skin
 Smell
 Taste
 Vision
 Hearing
 Kinestetic sense
 Vestibular sense.

4.  Normal and abnormal sensation :
 The nervous system is a complex system of nerve cells that send
signals around the body. It receives information about outside
world through sensory inputs.The various types of sensation are :
Skin, Smell,Taste,Vision, Hearing, Kinesthetic and Vestibular.
 Secondary processing disorders disrupt the processing the
sensory information by the nervous system resulting
inappropriate response, reactions or both. Individuals with
sensory processing disorder cannot process sensory process
effectively.

5. Types of
Sensation
Smell
Skin Hearing
Taste Vision Vestibular
senses

6. TYPES OF SENSATION
1. Skin
The network of nerve endings and touch receptors in the
skin called the somasensory.
It is responsible for sensation such as cold, warmth, rough,
pressure, tickle, pain, etching, etc.
Continuous disorder/Factual disorder: They include loss
of sensation pressure, warmth, cold and pain.

7. 2. SMELL
The nerve receptor for smell are located in the lining of the
upper Nasal passage.
When a smell is detected, the olfactory neurons generate an
impulse which is passed on to the brain along the olfactory
nerve.
Olfactory disorder: This includes sensivity to odor or absence
of recognition of certain odors.

8. 3. TASTE
The taste sensation occurs in the mouth when a substance
reacts chemically with Taste receptor cells.
The sensation of Taste called “gustation” give us four basic
tastes – sweet, sour, salty and bitter.
Gustatory disorder : These include decrease in taste
sensitivity or complete lack of Taste for certain substance.

9. 4. VISION
 The retina of each eye contains receptor cells responsible for
Vision. There are two kinds of receptor cells in the retina – roads
and lones.
 The retina is a continuation of the topic Vision. The retina carries
the visual simulations from retina to the occipital lobe in the brain.
 Visual disorder : The common visual disorders are myopia ( near
sightedness ), hyperopia ( far sightedness ), astigmatism and
color blindness.

10. 5. HEARING
Impulses are carried through the auditory nerves to
the temporal lobes of the brain.
Hearing plays an important role in the understanding
of spoken language. It is the principle sensory
modality for human communication.
Auditory defects : Hearing can be impaired by
injuries, fixation or disengagment of the occicles,
diseased tonsils, measles, mumps, etc.

11. 6. KINESTHETIC SENSE
Kinesthetic senses perform the very important function of
providing cells to our movements and maintain smooth and
continuous action.
Kinesthetic Sense : These refer to a failure to control
movements and inability to walk straight, etc.

12. 7. VESTIBULAR SENSE
The Vestibular senses monitor equilibrium and awareness
of body position and movement. The receptor for these are
the Vestibular in the inner part of the ear.
Vestibular disorder : Nausea and dizziness, inability to
maintain equilibrium ans posture.

13. • SUMMARY
Here, I summarized that Introduction of normal and
abnormal sensation, types of sensation, 1.skin 2.smell
3.taste 4.vision 5.hearing 6.kinesthetic senses 7.vestibular
senses.

14. • CONCLUSION
Here, I conclude that sensation and perception are distinct
but interconnected processes involved in our experience
of the world. Sensation involves the initial direction and
encoding of sensory stimuli, while perception involves the
interpretation and organization of sensory information into
meaningful experience.
