Your heart sits in the middle of your chest and pumps blood from about 4 weeks after conception until the day that you die. It never stops, and over your lifetime it will pump ~175 million liters of blood. To visualize that, imagine the amount of water that falls over Niagara falls in a few minutes. Remarkable! This little pump is the size of your clenched fist and in an adult can weigh about 300 grams.

HMP 607 is the third in a three-course sequence intended to impart to generalist administrators the knowledge of finance and accounting necessary to manage health care organizations. The first course, HMP 608, covers financial accounting. The second course, HMP 606, focuses on managerial accounting topics. This third course concentrates on corporate finance topics. It aims to impart an understanding of how finance theory and practice can inform the decision-making of the health care firm. As such, HMP 607 is most appropriately considered a corporate finance course, as opposed to a course in financial markets. In addition, it will integrate corporate finance and accounting theories, institutional knowledge of health care finance, and applications to specific problems.

This course will explore the different dimensions of sustainability in healthcare and ways to incorporate those ideas into the managerial and quality improvement processes of healthcare organizations. Then it will compare how those issues have been addressed in different healthcare systems around the world. The course will analyze and discuss the key elements of the five pillars of sustainability of healthcare organizations, which are: environmental, socio-cultural, institutional capacity development, financial, and political. We will review critical issues such as recycling medical waste; sustainable energy solutions for hospitals and healthcare organizations in countries with different levels of development; how to improve community health through sustainable healthcare; and many other issues equally relevant to large and small healthcare organizations in developed or developing countries. As the participants review and exchange lessons learned in different corners of the world, they will discover and exchange ideas and tools to assess the sustainability efforts of their organizations and to implement feasible strategies to advance their initiatives.

The neuroscience sequence is foundational in nature and stresses the organizational principles and structure/function relationships in the central nervous system. The course emphasizes the relationship between the gross organization of the Central Nervous System (CNS), its subdivision into specialized regions and the corresponding perceptions of sensory information and the nervous system control of behavior. The cell biology of the neuron, neurotransmitter systems and neuronal injury and repair are also emphasized.

This sequence provides the information and opportunities necessary for students to acquire integrated knowledge of the structure and function of the endocrine and reproductive systems in humans. Although all of the biological systems are clearly interrelated, the endocrine and reproductive systems are intimately linked. Much of what you learn about hormonal control and steroid biochemistry of the endocrine system will be referred to and used in teaching reproductive physiology.
