What is the role of sensory input in personality and intellectual function? - correct answer ✔Sensory
input is vital to the integrity of personality and intellectual function.
What can sensory deprivation cause? - correct answer ✔Sensory deprivation can cause hallucinations.
What is a sensory receptor? - correct answer ✔A sensory receptor is a structure specialized to detect a
stimulus.
What are the two types of sensory receptors based on structure? - correct answer ✔Bare nerve
endings and true sense organs.
What is modality in sensory receptors? - correct answer ✔Modality refers to the type of stimulus or
sensation produced, such as vision, hearing, or taste.
How is location encoded in sensory receptors? - correct answer ✔Location is encoded by which nerve
fibers are firing.
What is a receptive field? - correct answer ✔A receptive field is the area within which a sensory neuron
detects stimuli.
How does the brain encode stimulus intensity? - correct answer ✔By which fibers are sending signals,
how many fibers are doing so, and how fast these fibers are firing.
What is sensory adaptation? - correct answer ✔Sensory adaptation is when the firing of a neuron slows
over time if a stimulus is prolonged.
, What are phasic receptors? - correct answer ✔Phasic receptors adapt rapidly, generating a burst of
action potentials when first stimulated, then quickly reducing or stopping signaling.
What are tonic receptors? - correct answer ✔Tonic receptors adapt slowly, generating nerve signals
steadily throughout the presence of a stimulus.
What are the five primary taste sensations? - correct answer ✔Salty, sweet, sour, bitter, and umami.
What is the function of nociceptors? - correct answer ✔Nociceptors detect pain and provide different
pain sensations.
What is fast pain and how does it travel? - correct answer ✔Fast pain travels myelinated fibers at 12 to
30 m/s and is perceived as sharp, localized, stabbing pain.
What is slow pain and how does it travel? - correct answer ✔Slow pain travels unmyelinated fibers at
0.5 to 2 m/s and is perceived as a longer-lasting, dull, diffuse feeling.
What is referred pain? - correct answer ✔Referred pain is pain in the viscera that is mistakenly thought
to come from the skin or other superficial sites.
What are endogenous opioids? - correct answer ✔Endogenous opioids are internally produced opium-
like substances that act as pain modulators.
What are taste buds and where are they primarily located? - correct answer ✔Taste buds are sensory
structures mainly found on the tongue.
What is the role of basal cells in taste? - correct answer ✔Basal cells are stem cells that replace taste
cells every 7 to 10 days.
