Document preview thumbnail
Preview 1 out of 1 pages

This document is a 1 page, very condensed (written on IPad A3 notebook) summary with everything you need to know about the histology and anatomy of the eye (including the layers of the retina) and ear (including organ of corti), as well as some histology of the organ of taste. It uses some great schemes and visual aid to help in the understanding of the concepts. Please note that each different color will be corresponding to its color within the schemes, for proper orientation.
