In this embryology lecture, Professor Zach Murphy guides you through the development of the skeletal system, focusing on how bones and cartilage arise from mesodermal and neural crest-derived cells. This lecture explains the origins of the axial and appendicular skeletons, the molecular signals that guide their formation, and the two major types of ossification that shape the human skeletal framework. We begin by discussing the mesodermal contributions—particularly from the paraxial mesoderm (somites) and lateral plate mesoderm—and how these structures give rise to the vertebral column, ribs, sternum, limbs, and portions of the skull. Zach reviews the formation and segmentation of sclerotomes, and how they pattern the vertebrae in alignment with spinal nerves. The lecture then explores intramembranous ossification, which forms flat bones like the cranial vault, and endochondral ossification, which underlies the development of long bones through a cartilage model. You’ll also learn about the role of growth plates, chondrocyte differentiation, and key regulatory factors like FGF, BMP, and HOX genes.
