Exercise 22 — General Sensation Flashcards
changes within a person’s environment
stimuli
the body’s ______ ______ respond to stimuli
sensory receptors
receptors of the _______ senses are activated by touch, pressure, pain, heat, cold, stretch, vibration, changes in body position
general
the ______ senses include vision, hearing, smell, taste, and equilibrium
special
_________ are sensitive to stimuli in the external environment and are located close to the body’s surface
exteroceptors
5 types of cutaneous receptor
tactile corpuscle
free nerve endings
bulbous corpuscle
hair follicle receptor
lamellar corpuscle
_________ are sensitive to stimuli arising within the body and include stretch receptors, chemoreceptors, etc
interoceptors
_________ respond to internal stimuli but are limited to skeletal muscles, tendons, joints, ligaments, and connective tissue coverings of bones and ligaments
proprioceptors
_________ give information about body movement and position by monitoring amount of stretch
proprioceptors
tactile corpuscles respond to…
touch, light pressure
free nerve endings respond to…
pain, temperature
bulbous corpucles respond to…
deep continuous pressure
hair follicle receptors respond to…
hair movement, light touch
lamellar corpuscles respond to…
deep pressure
3 nonencapsulated receptors
free nerve endings
epithelial tactile complexes
hair follicle receptors
5 encapsulated receptors
tactile corpuscles
bulbous corpuscles
lemellar corpuscles
muscle spindles
tendon organs
________ and _______ are involved in proprioception
muscle spindles
tendon organs
the process by which environmental stimuli change into nerve impulses that are relayed to the CNS
transduction
awareness of the stimulus
sensation
conscious interpretation of the stimulus
perception
each location on the body is represented by a specific ______ _____
cortical area
the area served by a given sensory neuron
receptive field
the brain’s ability to determine which portion of the skin has been touched
tactile localization
when a stimulus is applied for a long period of time and rate of receptor discharge slows
adaptation
_____ receptors adapt very little, if at all
pain
a sensory experience in which pain is experienced as arising in one area of the body when another area is receiving the stimulus
referred pain
