` Histology Lab


Course Description

This course will introduce students to the cellular arrangements, morphologies and functions of the four major tissue types, connective, epithelium, nervous and muscle. Emphasis will be placed on the knowledge and skills required to identify and describe various organs at the microscopic level. Students will also acquire a good range of mental images through the repeated use of light microscopy.

The pedagogical goals of Histology are the following:

  • Appreciate the history of the study of tissues.
  • Gain acquaintance with some of the modern day techniques used to study tissues.
  • Study the structural organization and morphology of cellular components.
  • Develop comfort using the microscope to identify key structures of the various tissue types
  • Gain appreciation for the function of the various tissue types as they relate to their structures
