match the following sensations with associated mechanoreceptors
1-Tapping
2-velocity
3-pressure
4-location

Choices
Pacinian corpuscle,Meissnere's corpuscles in non hairy skin,Ruffinis corpuscles,and Merkel's disk on epithelial cells




  #2

tapping-Merkel
velocity -Pacinian
pressure Meissner
location -Ruffini


  #3

1. tapping: pacinian
2.velocity:meissner's
3.pressure: ruffini's
4.location: merkel's disk


  #4

asmi you are correct
Ref:BRS physio


  #5

Does anyone has Guyton or a Neurophysiology Textbook?
I looked in Guyton and these terms especially Meissner and Merkel appear somewhat ambiguous except for Pacinian which is associated with vibration and rapid changes in mechanical states of tissues.
*This is what Guyton says for Ruffini end organ--Its in the deeper layers of the skin and deep tissues.These endings adapt very little and are important for signaling continuous states of deformation of the skin and deeper tissues,such as heavy and continuous touch signals and pressure signals. They are also found in joint capsules and help signal degee of joint rotation.
My main point peekay is that a review book may not give the full story, but I appreciate the reference. Comments welcome.
