What Will I Learn?
  • Identify the primary patterns of bone growth and remodeling that occurs throughout the life of the bone and the stimulus that regulates these growth patterns
  • Identify how various stresses and strains are applied to the bone based on the concept of a stress-strain curve and how these stresses and strains is met with either resistance within, or fracture of, the bone
  • Discuss the impact of stress and strains on the bones morphology and physiology, based on Wolff’s Law for bone remodeling
  • Identify the stages of fracture repair and describe how the bone has become more resistant to that force which led to the initial fracture

Description

As the slogan makes you want to believe “milk it does your body good…” with the thought the calcium in the milk is what makes bones strong and keeps bones healthy, especially when combined with vitamin D.  Along with this dietary concept, we have been classically taught that there are two types of bone cells that based on our diet will influence the overall health and strength of the bones of body.  But how true are these concepts?  What actually makes bones function and stay “strong” throughout one’s life?  Bone is a tissue that is highly metabolic with a variety of cellular activities and regulatory mechanisms.  Activities and regulation of cells that function to ensure that our bones are capable of withstanding the stresses that we place upon them in our everyday activities.  This lesson will allow us to explore these issues through the concept of bone physiology and the principle of bone remodeling based on the concept of Wolff’s Laws.  In which we will delve into what is meant by cells being “Blastic” or “Clastic” and how these activities lead to changes in the bone’s density (usually called “bone mineral density).  And how all of this will impact the ability of the bone to resist stresses placed on it so it will not fracture. Lastly, we will delve into the concept of losing bone mineral density and the what constitutes the disease osteoporosis.

Who is the target audience?
  • The lesson is designed for students who are taking, or have taken, a human anatomy and physiology course and need some help understanding bone physiology.
  • The lesson is for anyone who wants to learn about how their body functions and what they can do to ensure that they have good bone health throughout their life

Physiologist, Health and Science Educator

With a background in physiology, sports medicine and health care, and education that is coupled with my many publications on the science of exercise and physiology related to obesity and health issues of obesity, I routinely find myself working with people and students to the point where they are able to have a better understanding of the general principles of health and fitness.  

In the classroom and lecture halls, I use a presentation style that makes every effort to pass information to students based on how they can make a practical application of the information in their chosen career paths. While my writing and presentations outside of the classroom, either at conferences or to general population, is done with an effort to convey the science of what we know (not what we think we know or what we hope were true) so that they can understand why health professionals would have them follow the recommendations that are given to them to do.

In these various endeavors, I have worked closely with each person to expand their understanding of the implications of exercise and fitness as it relates underlying scientific principle of physiology for their health or for medical professions to educate those in their care.

In the classroom and lab, I work with many students and members of our college community to understand that not all exercise methods are equal to each other,
and the concepts of how to establish exercise programs based on the science of exercise physiology. Additionally, understand that not everything that makes the popular press and news headlines are accurate (or even correct sometimes).
