The Skeletal System: Crash Course A&P

The video explores the effects of microgravity on astronauts' bones during long space missions, focusing on the year-long mission of Scott Kelly and Mikhail Kornienko. It delves into bone anatomy, including the axial and appendicular skeleton, and the microanatomy of bones, such as osteons and lamellae. The process of bone remodeling, involving osteoblasts and osteoclasts, is explained, highlighting the challenges astronauts face in maintaining bone density in space. The video concludes with a summary and credits.
