In this embryology lecture, Professor Zach Murphy walks you through the development of the muscular system, detailing how different types of muscle—skeletal, cardiac, and smooth—arise from distinct embryonic origins. This lecture emphasizes the key cellular lineages, molecular regulators, and anatomic organization that shape the body’s musculature. We begin with skeletal muscle development, which originates from the paraxial mesoderm, specifically the myotomes of somites. Zach explains how the epaxial and hypaxial divisions of the myotome give rise to the deep back muscles and the limb/trunk wall muscles, respectively, and how myoblasts fuse to form multinucleated muscle fibers. The lecture continues with cardiac muscle development from splanchnic mesoderm, focusing on how early cardiac myocytes differentiate and organize to form the heart’s contractile tissue. We also explore smooth muscle development, which varies based on location, arising from splanchnic mesoderm, neural crest cells, or even ectoderm in specialized regions.
