Question
Answer
the sensations caused by mechanical displacement of the skin   show
🗑
perception of the position and movement of our limbs in space   show
🗑
show proprioceptors  
🗑
collectively, sensory signals from the skin, muscles, tendons, joints, and internal receptors   show
🗑
wide-diameter, myelinated sensory nerve fibers ◦ Transmit signals from proprioceptive receptors in muscles and tendons   show
🗑
(slightly less) wide-diameter, myelinated sensory nerve fibers ◦ Transmit signals from mechanical stimulation   show
🗑
show a-delta fibers  
🗑
show c-fibers  
🗑
show a-alpha, a-beta, a-delta, C fibers  
🗑
sensory receptors that respond to mechanical stimulation (pressure, vibration, movement); connect to a-beta fibers ◦ Include SA I (Merkel), FA I (Meissner), SA II (Ruffini), and FA II (Pacinian)   show
🗑
sensory receptors that play an important role in sense of where limbs are, what kinds of movements are made ◦ Connect to A-alpha fibers and A-beta fibers   show
🗑
show thermoreceptors  
🗑
show nociceptors  
🗑
show tactile, thermal, pain, itch  
🗑
each fiber type from the skin codes a particular touch sensation   show
🗑
carries most of the information about skin temperature and pain (slower)   show
🗑
carries signals from skin, muscles, tendons, and joints (faster)   show
🗑
show homunculus  
🗑
the impression of our bodies in space   show
🗑
pain sensations are triggered by ____   show
🗑
a region of the brain associated with the perceived unpleasantness of pain sensations   show
🗑
show prefrontal cortex  
🗑
a description of the system that transmits pain that incorporates modulating signals from brain; bottom-up pain signals from nociceptors can be blocked via a circuit located in spinal cord; neurons in dorsal horn actively inhibit pain transmission   show
🗑
decreasing pain sensation during conscious experience   show
🗑
show hyperalgesia  
🗑
decreasing pain sensation when people think they’re taking an analgesic drug but actually are not   show
🗑
increasing pain sensation when people expect pain   show
🗑
show phantom limb  
🗑
show neural plasticity  
🗑
show two-point threshold  
🗑
knowledge of the world that is derived from sensory receptors in skin, muscles, tendons, and joints, usually involving active exploration ◦ For instance, aligning the arrows and opening a child-proof aspirin bottle in the dark   show
🗑
geometric properties of objects are most important for visual recognition   show
🗑
the inability to identify objects by touch; caused by lesions to parietal lobe   show
🗑
show the "where" system of touch  
🗑
the coordinate system used to define locations in space   show
🗑
the center of a reference frame used to represent locations relative to the body   show
🗑
show thermoTRP  
🗑
show dorsal horn  
🗑
referring to spatial mapping in the somatosensory cortex in correspondence to spatial events on the skin   show
🗑
a system that attempts to closely mimic biological signals   show
🗑
show endogenous  
🗑
show exogenous  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
