◉ What is adaptation in sensory perception? Answer: The ability to no
longer perceive sensations due to prolonged exposure.
◉ What are the three categories of sensory receptors? Answer: Based on
distribution, location, and type.
◉ What do free nerve endings detect? Answer: Pain, temperature
changes, tickle, and itch.
◉ What sensations do encapsulated nerve endings respond to? Answer:
Touch, pressure, and vibration.
◉ What are exteroceptors? Answer: Sensory receptors that detect
sensations from outside the body.
◉ What are interoceptors? Answer: Sensory receptors that detect
sensations from inside the body.
◉ What do proprioceptors sense? Answer: The position of the body in
space and time.
, ◉ What type of receptors are mechanoreceptors? Answer: Receptors that
respond to stretch, touch, pressure, vibrations, and proprioception.
◉ What do nociceptors detect? Answer: Pain, which can be fast (acute)
or slow (chronic).
◉ What is referred pain? Answer: Pain perceived at a location other than
the site of the painful stimulus.
◉ What do Meissner's corpuscles detect? Answer: Light touch and low
frequency vibration.
◉ What is the function of Merkel cells? Answer: They detect pressure.
◉ What do Ruffini's corpuscles sense? Answer: Light and deep pressure.
◉ What is the role of Pacinian corpuscles? Answer: They detect
vibration.
◉ What are the special sensory receptor cells in the eye? Answer: Rods
and cones, which are photoreceptors.
