BIOL 2223: Human Anatomy and Physiology II

Unlock the language of genetic history with our guide to understanding pedigrees and their symbols. Learn how to interpret squares circles and lines to track inheritance patterns for traits and diseases.

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.

Unpack the intricate process of sound transduction, from the initial vibrations in the ear to the transformation into neural signals. Learn about the vital roles of cochlea, basilar membrane, and hair cells in deciphering our auditory world. A comprehensive guide to the magic behind our hearing.

Unravel the mysteries of food chain lengths by analyzing various factors. We spotlight the 10% rule in ecology, emphasizing how energy transfer inefficiencies mold ecosystem structures and functions.

Explore the sensory marvels of the male silkworm moth known as Bombyx mori and how they detect specific chemical signals from females. Uncover a hypothesis about the unique sensitivity of the moth's antennae and a prediction stemming from it. Learn how to design an experiment to test this hypothesis and deepen your understanding of insect behavior.

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
