BIO 1070: Health and Disease

Learn about muscle fascicle patterns and their role in human anatomy. Our video zeroes in on the convergent pattern found in the pectoralis major. Compare this with other muscle types like the biceps brachii and gluteus maximus to deepen your anatomical knowledge.

Unveil the essential muscles that make breathing possible in this video. Learn why the diaphragm and scalene are crucial players and why other muscles like the trapezius and semispinalis aren't involved in respiration.

Discover how humans adapt to cold environments through thermoregulation processes. Understand the body's heat conservation and generation mechanisms. Learn why certain physiological responses occur in cold conditions.

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.

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 which metabolic pathway is the heavyweight champion of ATP production. We'll evaluate contenders like lactic acid fermentation, the Krebs cycle, and more to determine the top ATP generator.
