Senses Flashcards
What are the specialized cells that monitor conditions inside or outside of the body?
Sensory Receptors
What’s the area monitored by a single receptor cell?
Receptive Field
What is the conscious awareness of a sensation is called?
Perception
What’s the reduction in the sensitivity in presence of a constant stimulus called?
Adaptation
What are the four classes of general sensory receptors?
Nociceptors, Thermoreceptors, Mechanoreceptors, Chemoreceptors
What do nociceptors respond to?
Pain
What do thermoreceptors respond to?
Temp
What do mechanoreceptors respond to?
Touch
What do chemoreceptors respond to?
Chemical stimuli
Whats the sensation that happens when the burning or aching pain that is transmitted by unmyelinated axons?
Slow pain
The perception of pain in an unrelated area of the body is called:
Referred pain
What are taste and smell are examples of?
Special senses that use chemoreceptors
What are the three classes of mechanoreceptors?
Tactile, Baroreceptors, and Proprioceptors
What do tactile mechanoreceptors respond to?
Touch
What do baroreceptors respond to?
Pressure
What do proprioreceptors resond to?
Positions (joints)
What does the term olfaction represent?
“Smell”
What are the regenerative stem cells in the olfactory epithelium called?
Basal Cells
What are chemicals in the air that stimulate olfactory receptors?
Odorants
Why do we have emotional and behavioral responses to smell?
Odors take a direct route to the limbic system, which then goes to emotions and memory
What is the only sensory information not routed through the thalamus?
Smell
Where are gustatory receptors found?
They are found in the gustatory cells of the taste buds
What are the five primary taste sensations?
Sweet, Sour, Bitter, Salty, and Umami
Where are the greatest number of taste buds found?
The back of the tongue
