Touch Me!

by Greg Crowther


Context

This jingle is about the touch and pressure receptors in the skin. Whether students should know the differences between Meissner's (tactile) corpuscles, Pacinian (lamellated) corpuscles, Ruffini (bulbous) corpuscles, and Merkel (tactile) discs is up to their instructor. Personally, I am most interested in the general mechanism of mechanotransduction that all of these receptors have in common. The melody of this jingle jumps back and forth between pitches that are a half step apart to convey the idea of distortion.


Lyrics

CHORUS:
Touch me! I said, touch me!
You'll distort the plasma membrane of mechanoreceptors.
Touch me! I said, touch me!
You'll distort the ion channels sitting in the plasma membrane.

Ion current changes;
Membrane potential changes;
Release of transmitter changes;
Yes, they all work like this.
Meissner's corpuscles;
Pacinian corpuscles;
Ruffini corpuscles;
And Merkel discs.

CHORUS

Touch me!

Lesson Plan

Songs like this one can be used during class meetings and/or in homework assignments. Either way, the song will be most impactful if students DO something with it, as opposed to just listening.

An initial, simple follow-up activity could be to answer the study questions below. A more extensive interaction with the song might entail (A) learning to sing it, using the audio file and/or sheet music as a guide, or (B) designing kinesthetic movements ("dance moves") to embody it. The latter activity should begin with students identifying the most important or most challenging content of the song, and deciding how to illustrate that particular content.


Study Questions

(1) Are there any other sensory receptors in the skin besides those listed?

(2) Where else in the body do mechanoreceptors occur?

(Answers may be found on the answers page.)
