A Digital Resource on The Integument
Welcome to this digital resource on the histology
of the integument. This resource is designed to
aid your mastery of the integument by allowing
you to revisit the material presented during
lab. The material presented here corresponds with
the material presented during lab. In fact you
will need your lab exercise, the Histology of the
Integument to progress through this digital
resource. We hope you find this material
helpful. However it should not take the place of
slide observation in the laboratory. To fully
appreciate histological detail and completely
explore a slide of the integument you should
observe the slide through the microscope. Also
all slide tests involve histology presented
through the microscope.
