13: Senses Flashcards
What are the two classes of senses? What senses are in each?
General (temperature, pain, touch, stretch, and pressure)
Special (gustation, olfaction, vision, equilibrium, audition)
How are stimuli detected?
Through RECEPTORS
What are the 5 types of receptors?
Chemoreceptors
Thermoreceptors
Photoreceptors
Mechanoreceptors
Nociceptors
What do mechanoreceptors detect?
Touch
Pressure
Vibration
Sound
Body position
What detectors detect temperature?
Thermoreceptors
What do nociceptors detect?
Tissue damage, possibly resulting in chemical pain
What is a extereceptor?
A receptor that is located near a stimulus in the external environment
What is an interoceptor?
Receptor that interprets stimuli from internal organs and tissues, such as an increase in blood pressure
What is a proprioceptor?
Interprets the positions of tissues as they move, such as near a muscle
What is a chemoreceptor?
Interprets chemical stimuli, such as taste or smell
What receptors interpret light?
Photoreceptors
What is proprioception?
Body position
What kind of sense is somatosensation?
General
Where are receptors for general senses found?
All across the body in various organs
Where are receptors found for special senses?
In organs dedicated to that sense
Where are receptors for proprioception found?
Joints and muscles
What is the name of a stretch receptor in a skeletal muscle?
Muscle spindles
What is the name of a stretch receptor in a tendon?
Golgi tendon organs
What are stretch receptors called in joints capsules?
Bulbous corpuscles
Where do babies have taste buds that adults do not?
Foliate papillae
Where do adults have most of their taste buds?
Circumvallate papillae
