About this resource (pdf)

History:   This website was initially created by David G. King (currently Associate Professor Emeritus at Southern Illinois University Carbondale) during several years in the early 2000s, with support from the SIU School of Medicine.  That support was discontinued in July of 2021, at which time this website was re-established at its present location.

Questions, comments, or error notes are welcome, sent to the email address at the bottom of each page

Accessibility:  Most images in this website are micrographs illustrating the accompanying text.  That text can be read without regard to the images, except to note that most small images are links to pages whose accompanying text describes details within enlargments of those images.  Because "alternative text" could do little more than duplicate that accompanying text, "alternative text" is not provided for most images.
