BIOL 5230: Comparative Animal Physiology

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity

Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.

Explore the crucial role of red marrow in producing vital blood cells and maintaining the circulatory and immune systems. Learn why bones are essential for blood cell production and understand why other options are incorrect.

Unravel the intricacies of the Autonomic Nervous System (ANS) and its pivotal role in controlling involuntary bodily functions. Differentiate between the sympathetic and parasympathetic systems and their unique contributions. Debunk misconceptions surrounding the ANS's characteristics.

Discover the intriguing behavioral responses of ants, triggered by chemical cues. This video explains how ants instinctively handle their dead, highlighting the significance of fixed action patterns in animal behavior. Learn how biology and behavior seamlessly connect in the complex world of ants.

Gain a clear understanding of chemical equilibrium, where reactant and product concentrations stay constant due to equal forward and reverse reaction rates. Dispel common misconceptions about equilibrium, such as concentration equality and reaction reversibility.
