Taste & Smell: Crash Course A&P

The video explores the story of Olivia, who suffers from anosmia, a loss of smell, due to head trauma. It explains sensory transduction, focusing on how our senses, particularly smell and taste, work. The olfactory system's process is detailed, showing how smell is detected and processed in the brain. The connection between taste and smell is highlighted, emphasizing that taste is largely dependent on smell. The video debunks the myth of taste maps on the tongue and explains the physiological process of taste. It concludes with a summary and credits.
