BIOL 283: Animal Physiology

Grasp the fundamentals of how neurons transmit electrical signals through action potentials. Understand the crucial role of myelination and fiber diameter in efficient nerve impulse conduction. Dive into the comparisons of different nerve fiber types and their properties.

Unravel the origins of blood cell types as we differentiate between myeloid and lymphoid stem cells, highlighting the unique lineage of platelets, B cells, and Natural Killer cells.

Explore the essential role and composition of blood plasma in our body. Understand how water, as the main component, helps in maintaining vital functions. Learn the importance of plasma balance for overall health insights.

Explore the intricate eukaryotic cell structure, from the protective plasma membrane to the vital organelles. Learn how DNA, ribosomes, and the cytoskeleton play pivotal roles in cellular function. Dive deep into the world of mitochondria, ER, and the Golgi apparatus.

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

In this video we explore the unique characteristics that set animals apart from other organisms. We evaluate options like gastrulation multicellularity sexual reproduction and flagellated sperm. Conclusively we identify gastrulation as a truly unique process in animal embryonic development.
