Our conscious
awareness of
stimuli is known as
What is sensation
(perception)?
EC – What is the general name of
structures that are able to receive
sensation?
The one that is NOT a
general sense – Touch,
Temperature, Pain,
Taste, Proprioception. . .
What is Taste?
EC – Define Proprioception.
These type of
receptors relay
information to the brain
about temperature
changes.
What are
thermoreceptors?
EC – Name another type of receptor
that is specifically associated with the
general senses?
Pain felt in a region of
the body that is not the
ultimate source of the
pain, an example being
pain in the left arm as a
result of a heart attack
is termed
What is referred
pain?
Merkel’s disks, hair follicle
receptors, Meissner’s
corpuscles and Ruffini’s
end organs are all
associated with this
general sense.
What is touch?
EC – Can you name the one
specific type of touch receptor
not previously listed?
The scientific name
for the sense of
smell is
What is olfaction?
Olfactory neurons
have specialized
dendrites with
these extremely
long extensions . . .
What are cilia?
EC – What is the purpose of the
cilia as it relates to smell?
Ultimately, this is
the reason why
things smell . . .
What are different
molecules (odorants)
bind to receptors in
the nose?
Name one of two
reasons why your
ability to smell the
same odorant
decreases after a
period of time.
What is olfactory neurons can
only send one message at a time
to the brain and/or there are
feedback loops from the brain
that decrease sensation after
the same message is received a
given number of times?
This is the name of the
discontinuous bony
structure at the roof of
the nasal cavity where
odorants bind to
olfactory neurons.
What is the cribriform
plate of the ethmoid
bone?
This is the
scientific name for
the sense of taste.
What is gustation?
The sensory
structures that
detect taste are
known as
What are taste
buds?
The bumpy
structures on the
surface of the tongue
where taste buds are
found are called this.
What are papillae?
EC - What is the purpose of
papillae on the tongue?
Name the five
different taste
sensations.
What are sweet,
sour, salty, bitter
and umami?
EC – What does umami mean?
This is the name of the
structure that extends
from the taste cell that
functions as a binding
spot for food molecules.
What is a taste
hair?
This is the name of
the gland that
produces tears.
What is the
lacrimal gland?
Structure seen at #9, this connective tissue is
casually known as the “whites” of your eyes.
What is the sclera?
EC – What layer of tissue is just
deep to the sclera?
These specialized
cells detect color
What are cones?
EC – Where would you find these
specialized cells?
This circular muscle
provides eye color
What is the iris?
EC – What type of muscle is the
iris?
Name two structures seen in this picture that
refract light.
What are the
cornea and the
lens?
EC – Which one of the humors
can also refract light to an
extent?
This is the
scientific name for
the eardrum.
What is the
tympanic
membrane?
The hammer, anvil
and stirrup
scientifically.
What is the
malleus, incus and
stapes?
The fleshy part of the ear, indicated
by #2 above is known as the . . .
What is the
auricle?
EC – What is the name for the
hole in the ear?
This tube connects
the ear to the nasal
passages . . .
What is the
auditory tube
(eustachian tubes)?
The circular structures indicated by #15
above are responsible for equilibrium.
What are the
semicircular canals?
EC – Are these structures more
involved with hearing or
equlibrium?
Final Jeopardy:
Equilibrium
What are the two types
of equilibrium, where
are they detected, and
what is the difference
between the two?
Static Equilibrium
- detected in vestibule of the
cochlea
- detects position of head with
respect to gravity
Kinetic Equilibrium
- detected by semicircular canals
- maintains balance for coordinated
movements by evaluating changes in
direction of the head and the rate
of change to head position.
