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.
