Course Sneak Peek: Introduction to Biomechanics and Mechanobiology

Key Concepts

• Biomechanics: The study of the mechanical principles governing the movement of living organisms.
• Mechanobiology: The study of how mechanical forces and changes in tissue mechanics affect cellular processes and ultimately, organismal development and disease.
• Tissue Mechanics: The characterization of the mechanical properties of biological tissues (e.g., stiffness, elasticity, viscosity).
• Mechanical Systems: Specific bodily systems exhibiting mechanical function (e.g., cardiovascular, respiratory).
• Mechanical Cues: Physical forces or changes in the mechanical environment that influence biological processes.

Course Overview: Biomechanics and Mechanobiology

This course provides a comprehensive exploration of biomechanics and mechanobiology, encompassing both the descriptive analysis of tissue mechanical properties and the investigation of how these properties influence biological systems. The course is structured in three primary sections, culminating in industry-focused guest lectures.

Tissue Mechanics – Foundational Principles

The initial segment of the course will focus on tissue mechanics. This involves learning how to characterize and describe the mechanical properties of various biological tissues. The emphasis will be on understanding not just what these properties are, but also their functional role within specific physiological contexts. No specific tissues were named, but the implication is a broad survey of different tissue types and their mechanical behaviors.

Mechanical Systems in the Body – Application of Principles

Following the foundational understanding of tissue mechanics, the course will transition to examining specific mechanical systems within the human body. Two systems explicitly mentioned are:

• Cardiovascular System: The mechanics of the heart, including its pumping action and the properties of heart tissue.
• Respiratory System: The mechanics of the lungs and the process of breathing.
• Blood Flow: The mechanics governing the movement of blood through the circulatory system.

This section will apply the principles learned in the tissue mechanics portion to understand the function of these complex systems.

Mechanobiology – Force as a Biological Signal

The core of the course then shifts to mechanobiology. This section investigates how mechanical cues – forces and changes in the mechanical environment – influence biological processes. Specifically, the course will explore how these cues shape the development of the musculoskeletal system. However, the scope extends beyond this system, indicating that mechanical cues impact the development and function of other systems as well. The transcript doesn’t detail which other systems will be covered.

Industry Applications & Guest Lectures

The final component of the course involves guest lectures from professionals in various industries. These lectures will demonstrate the practical application of biomechanics and mechanobiology principles to real-world biomedical applications. The transcript highlights that these professionals utilize these concepts in their daily work, suggesting a focus on translational research and engineering.

Logical Flow & Course Structure

The course follows a logical progression, starting with the fundamental principles of tissue mechanics, applying these principles to specific bodily systems, and then expanding to the broader field of mechanobiology. The inclusion of industry guest lectures bridges the gap between theoretical knowledge and practical application.

Synthesis

The overarching goal of this course is to equip students with a robust understanding of both biomechanics and mechanobiology, enabling them to analyze biological systems from a mechanical perspective and appreciate the crucial role of mechanical forces in shaping life processes. The course emphasizes both foundational knowledge and its relevance to solving real-world biomedical challenges.
