Strata of the Epidermis

by Greg Crowther


Context

This jingle lists the 5 layers of the epidermis of the skin, from innermost to outermost: stratum basale, stratuum spinosum, stratum granulosum, stratum lucidum (for thick skin only), and stratum corneum. These layers are all considered epithelial tissue.


Lyrics

Basale, spinosum, granulosum, lucidum, corneum!
Bottom to top, an inverted cemetery.
Basale, spinosum, granulosum, lucidum, corneum!
Dead cells above, and the living ones buried!


Other Files

MP3 (demo)

sheet music (with melody play-back)


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) Which layer is closest to cutaneous capillaries?

(2) In which layer do melanocytes normally reside?

(3) What is the predominant protein in the dead cells of the outermost layers?

(4) Of the five layers listed, which one is only present in thick skin, such as the skin on the palms of your hands and the soles of your feet?
