Human Anatomy: Unit 2

Discover the fascinating mechanics of human joints, from bone carpentry and synovial fluid to the engineering trade-offs between mobility and stability. We break down joint classifications, movement vocabulary, and the complex anatomy behind the shoulder, hip, and knee.

Explore the architecture of the human skeleton, tracing how over 60 bones fuse from infancy to adulthood across the axial and appendicular systems. Learn about the cranial cavities, spinal curves, and the structural compromises between shoulder mobility and pelvic stability.

Discover why the human skeleton is far from a static scaffold, functioning instead as a dynamic, living organ that constantly remodels itself. From the microscopic architecture of osteons to the rapid bone loss astronauts face in microgravity, we explore how mechanical stress and specialized cells rebuild your bones from the inside out.
