Tissues are a collection of cells that act as a functional unit. In this case, cells make up the tissues of the arties and veins.
This course presents the microscopic structure of cells, tissues, and organs, with emphasis on the correlation of structure and function. Vignettes of clinical and pathologic significance are also presented.
In this lab, the student will review the anatomy and histology of the organs by using images of models, microscopic slides, and videos on cat and sheep dissections. The student will then be asked to assess his or her knowledge, which eventually can be put to practical or experimental use. Upon successful completion of this lab supplement, students will be able to: use anatomical terminology correctly in the laboratory; using a compound light microscope, identify different tissues and describe a human organ where that tissue can be found; describe the major features and functions of human skin; identify and name human bones and their major features and differentiate, microscopically and grossly, between compact and spongy bone; name and describe the functions of the human brain's major structures; describe the anatomical and functional differences between the dorsal and ventral roots of spinal nerves and the dorsal and ventral horns of the spinal cord's grey matter; describe the structure of an intervertebral disc; identify, microscopically and grossly, the differences between the three types of muscle and describe the respective structures and locations of different muscle tissues; identify and name the structures of the human eye and the human ear; describe the major similarities and differences in the structure of an artery and a vein; describe the flow of blood through the heart and identify all major vessels, chambers, and valves; identify and name, histologically and anatomically, the major components of the respiratory system, the digestive system, and the male and female urinary systems; identify and name, histologically and anatomically, the major components of male and female reproductive systems.

Explores the interaction of radiation with matter at the microscopic level from both the theoretical and experimental viewpoints. Emphasis on radiation effects in biological systems. Topics include energy deposition by various types of radiation, including the creation and behavior of secondary radiations; the effects of radiation on cells and on DNA; and experimental techniques used to measure these radiation effects. Cavity theory, microdosimetry and methods used to simulate radiation track structure are reviewed. Examples of current literature used to relate theory, modeling, and experimental methods. Requires a term paper and presentation. The central theme of this course is the interaction of radiation with biological material. The course is intended to provide a broad understanding of how different types of radiation deposit energy, including the creation and behavior of secondary radiations; of how radiation affects cells and why the different types of radiation have very different biological effects. Topics will include: the effects of radiation on biological systems including DNA damage; in vitro cell survival models; and in vivo mammalian systems. The course covers radiation therapy, radiation syndromes in humans and carcinogenesis. Environmental radiation sources on earth and in space, and aspects of radiation protection are also discussed. Examples from the current literature will be used to supplement lecture material.
Principles of mass transport and electrical signal generation for biological membranes, cells, and tissues. Mass transport through membranes: diffusion, osmosis, chemically mediated, and active transport. Electric properties of cells: ion transport; equilibrium, resting, and action potentials. Kinetic and molecular properties of single voltage-gated ion channels. Laboratory and computer exercises illustrate the concepts. For juniors and seniors. Students engage in extensive written and oral communication exercises.
