Detailed Description of Conduct of Course

The lecture portion of the course may be conducted using a variety of techniques and aids in addition to the traditional lecture style of format. A variety of visual aids including slides, videos, movies, and computer generated graphics will be used to enhance the lectures. Class discussion will be encouraged. The laboratory experience will primarily be devoted to an examination and analysis of prepared sectioned tissue samples using compound light microscopy.

 

Goals and Objectives

Having completed this course the student will be able to recognize, using light microscopy, the primary mammalian tissue types, as well as the histology of the mammalian organ systems, in normal, non-pathological condition. The student will be able to discuss the structure - functional relationships.

The student will have gained insights that should allow them to make predictions about function based on structure even when they have not previously seen the tissue. The student will have gained the knowledge of the process of tissue preparation for light microscopy.

 

Assessment Measures

Students will be tested on their knowledge of Histology through a variety of tests and quizzes that include essays, definitions, matching, multiple choice, drawings, and identification of microscopic sections and whole mounts. Students may also be evaluated on their contributions to discussions.
