• Don't share food, drinks, utensils and other similar items.
• If you’re sick, stay home!!! Email me about your situation and we will
work it out.
OBJECTIVES
#1- ANATOMY: To understand the structural
basis for the functioning of a living organism
Close relationship between structure and function
GROSS ANATOMY (macroscopic)
ANATOMY
HISTOLOGY (microscopic)
OBJECTIVES
#2- TECHNICAL ADVANCES: To appreciate that
our ability to answer questions is driven by the
development of new technology
Why study histology?
What are the uses of histological techniques
and microscopic tissue identification?

frozen and paraffin-embedded tissue
of a rat organ.
Techniques: microtome sectioning, frozen sectioning with
cryostat, staining, immunohistochemistry, fluorescence
microscopy, bright field microscopy, imaging, image
processing.
