BIOL 2651: Human Anat & Physiology I

Explore the groundbreaking heterotroph hypothesis by Alexander Oparin. This video outlines how the first organisms likely consumed pre-existing organic matter reshaping how we think about the origins of life and evolution

Discover the origins of specialized cells in embryonic development and learn about the three essential germ layers: ectoderm, mesoderm, and endoderm. Explore how these layers form the foundation for all multicellular life.

Explore the intricate process of mitosis and the crucial role it plays in cellular division. Learn how cell cycle control mechanisms, including cyclin degradation and Maturation Promoting Factor (MPF) activity, ensure accurate and regulated cell division.

Explore the profound impact of oceans on the biosphere in this video. Discover how oceans contribute to oxygen production, carbon dioxide absorption, and climate moderation, while also uncovering their limitations in regulating the pH of freshwater biomes and terrestrial groundwater.

Discover the concept of negative feedback loops in biological systems, where balance is maintained by counteracting changes. Explore the four key components: Stimulus, Sensor, Control Center, and Effector, through examples like blood sugar regulation. Uncover how these loops play a crucial role in keeping our body systems in harmony.

Discover the roles of sensory, interneurons, and motor neurons in the nervous system. These specialized cells transmit, process, and execute commands, orchestrating our responses. Experience the seamless coordination that enables us to interact with our environment.
