3 Recent Discoveries in Anatomy
Scientists and educators have worked tirelessly for centuries to discover and interpret all of the secrets of human anatomy. We know, for instance, that the body contains 206 bones and approximately 60,000 miles of veins, arteries and capillaries. Yet, thanks to rapid advancements in medical research and technology, new discoveries continue to reveal intricate details about our anatomy, and many breakthroughs are unfolding right before our eyes. Here are examples of recent findings: #1 Protective Barrier in the Brain Scientists at the University of Rochester found a previously unknown compartment in the subarachnoid area of the brain, which acts as the brain’s immune defense system. The layer consists of a thin section between the skull and brain filled with cerebrospinal fluid, and has several responsibilities: Physical protection: Acts as a cushion, protecting the brain from impact. Nutrient and waste transport: Facilitates nutrient delivery and waste removal. Immune surveillance: Enables immune cells to identify and respond to pathogens or abnormal cells. Scientists are optimistic about the impact this newly discovered compartment may play in treating neurological diseases, like multiple sclerosis and Alzheimer’s. Both conditions involve immune dysregulation within the brain, and the hope is that this compartment may play a role in developing targeted therapies that could improve the outlook for both diseases. #2 A New Layer of Muscle in the Jaw Try moving your lower jaw backward, toward your ears
