MCB 252: Cells, Tissues & Development

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Uncover the fundamentals of human muscle contraction and anatomy in this lesson. Highlighting the distinct roles of muscle origin and insertion we clarify their functions in movement. Learn why the muscle origin is the cornerstone of stability during contraction anchoring our body mechanics.

Explore the anatomy of white and gray rami communicantes, their ties to spinal nerves, and the distinct fibers in each ramus. Learn how the myelinated fibers of white rami differ from the unmyelinated fibers in gray rami. Gain a deeper understanding of our nervous system's complexity through these intricate relationships.

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

We explore how to determine the nature of a mysterious, gelatinous substance found on a forest rock. By conducting a series of tests, including microscopy, DNA staining, respiration observation, and growth experiments, we aim to unravel whether this enigmatic material is alive, inanimate, or a product of a living organism.

Explore the underlying causes of muscle fatigue and the crucial role of lactic acid. Understand the impact of ATP depletion and anaerobic metabolism on muscle performance. Gain insights into planning effective exercise and recovery strategies.
