What's happening around us?
This detection of environmental stimuli using your basic senses.
What is SENSATION?
Vision relies on this electromagnetic stimulus.
What is LIGHT?
These mechanical stimuli use vibrations to produce sensation.
What are SOUND WAVES?
These sensory systems are activated by chemical stimuli.
What are OLFACTION (smell) & GUSTATION (taste)?
This sensory system located in our inner ear has nothing to do with hearing.
What is the VESTIBULAR SENSE (sense of balance)?
The minimum intensity of stimulation that must occur before you experience sensation 50% of the time
What is ABSOLUTE THRESHOLD?
These help you see in color, while their neighbors allow you to see in low light. **you must identify which is which when you answer the question**
What are CONES & RODS?
This sense organ processes sound through the bending and vibrations of tiny hair cells.
What is the COCHLEA?
The only sense whose information does not pass through the Thalamus.
What is OLFACTION?
The sensation of "hot" is produced by the activation of these.
What are THERMORECEPTORS?
These two chemical sensory systems.
What are OLFACTION (smell) & GUSTATION (taste)?
The focal point of your retina.
What is the FOVEA?
Three tiny bones that transfer sound waves from the eardrum to the cochlea.
What are the MALLEUS (hammer), INCUS (anvil), & STAPES (stirrup)?
These are the six basic tastes.
What are SWEET, SALTY, SOUR, BITTER, UMAMI, & OLEOGUSTUS?
This sensation allows you to move in coordinated ways without having to look at the body part you are moving.
What is KINESTHESIS?
Bipolar & ganglion cells in your sense organs turn the environmental stimuli into neural signals.
What is TRANSDUCTION?
This muscle in your eye will expand and contract in response to changes in the weather (among other conditions).
What is the IRIS?
This type of deafness can be treated via a cochlear implant.
What is SENSORINEURAL DEAFNESS?
These chemical messages are processed by our olfactory system; most of the time they are processed unconsciously.
What are PHEROMONES?
An amputee whose right foot was removed often feels an itching sensation in his right foot.
What is PHANTOM LIMB SENSATION?
The majority of people rely most heavily on this sense.
What is VISION?
The place in our eye where we cannot see. **You must identify and explain why we cannot see from that point**
What is the BLINDSPOT (the place where the OCULAR NERVE connects to the eyeball.
This theory of sound perception is based on the idea that higher pitches travel faster and lower pitches travel slower.
What is the FREQUENCY THEORY?
Without the sense of smell, taste sensations are either muted or not experienced.
What is SENSORY INTERACTION?
This pain theory proposes that the spinal cord blocks some pain signals from reaching the brain.
What is GATE-CONTROL THEORY?
