Leonardo da Vinci once proclaimed this sentiment.

According to this renowned Renaissance artist,
the
five senses
are the key to truly experiencing and
embracing life. His view supports the reality that each
sensory organ transmits
sensation
to the brain to help
us comprehend and interpret the world around us.
•
The sensation
is the process through which our
brains receive information through our five senses,
which the brain then experiences and perceives.
•
The senses involved are sight, smell, hearing, touch,
and taste.
•
We view the world through our five senses. Our bodies
would be rendered functionally worthless without them.
In reaction to a physical phenomenon, the five senses
function through body parts and sense organs that
supply data for interpretation via a network of nerves.

All sense organs have distinct functions designed to
accomplish different goals.
Body Senses and Organs
•
Body organs enable us to see, smell, hear, touch, and
taste.
Sight
•
The
visual system, or sense of sight,
is responsible
for
visual perception
and is dependent on the
transduction of light impulses received via our eyes.
•
Vision as one of the senses is essential since it supplies
the brain with the most information per second.
•
The eyes are the primary sensory organ capable of
detecting shape, color, motion, and depth.
Smell
•
The
olfactory system
refers to the biological
components that support the sense of smell.
•
Specialized sensory cells called olfactory sensory
neurons are present in a small patch of tissue high
within the
nose
that give us the capacity to smell.
•
The sense of smell helps us detect and distinguish
distinct odors.
•
Different scents are either good, bad, or neutral based
on the feelings they provoke.
Hearing
•
The
auditory system
senses sound by detecting
vibrations via the
ear
.
•
Your ears gather sound waves, turned into neural signals
and delivered to the brain.
•
In the brain, they are associated with previous
experiences and presented as the sounds we hear.
•
Hearing
helps you communicate with people, experience
the senses and sounds of nature, provide personal safety,
and sustain mental health.
Touch
•
The
somatosensory system
known as the sense of
touch comprises multiple sensations sent to the brain
via specific skin neurons.
•
The skin is the body's largest organ and has many
receptors that help you feel what you touch. It senses
cold, hot, smooth, rough, pressure, tickling, itch, pain,
and vibrations, all controlled by this system.
•
The sense of touch impacts our lives from feeding to
walking, sexual behavior to social connections.
Taste
•
The
gustatory system,
known as the sense of taste, is a
sensory process involved in flavor
perception
.
•
This sense is triggered when a substance in the mouth
chemically interacts with taste receptor cells on the
taste buds located on the tongue.
•
The tongue distinguishes between five specific flavors:
sweet, sour, salty, bitter, umami (meaty). It can also
detect cool and hot.

Leonardo da Vinci emphasized the significance of the five senses in experiencing life fully. Our sensory organs - sight, smell, hearing, touch, and taste - play vital roles in transmitting information to the brain for interpretation. Each sense has distinct functions essential for perceiving and understanding the world around us, highlighting the importance of our sensory systems in cognition.

Sensory organs and their role cognition SESSION 10 Dr. Chitrasena Padhy Associate Professor Agricultural Extension
Leonardo da Vinci once proclaimed this sentiment. According to this renowned Renaissance artist, the five senses are the key to truly experiencing and embracing life. His view supports the reality that each sensory organ transmits sensation to the brain to help us comprehend and interpret the world around us. The sensation is the process through which our brains receive information through our five senses, which the brain then experiences and perceives.
The senses involved are sight, smell, hearing, touch, and taste. We view the world through our five senses. Our bodies would be rendered functionally worthless without them. In reaction to a physical phenomenon, the five senses function through body parts and sense organs that supply data for interpretation via a network of nerves. All sense organs have distinct functions designed to accomplish different goals.
Body Senses and Organs Body organs enable us to see, smell, hear, touch, and taste. Sight The visual system, or sense of sight, is responsible for visual perception and is dependent on the transduction of light impulses received via our eyes. Vision as one of the senses is essential since it supplies the brain with the most information per second. The eyes are the primary sensory organ capable of detecting shape, color, motion, and depth.
Smell olfactory system The refers to the biological components that support the sense of smell. Specialized sensory cells called olfactory sensory neurons are present in a small patch of tissue high within the nose that give us the capacity to smell. The sense of smell helps us detect and distinguish distinct odors. Different scents are either good, bad, or neutral based on the feelings they provoke.
