Final answer:
Schwann cells have an embryonic origin from neural crest cells during embryogenesis.
Step-by-step explanation:
Schwann cells, a type of glial cell, have an embryonic origin. During embryogenesis, Schwann cells derive from neural crest cells, which are a transient population of cells that migrate from the neural tube during development. These neural crest cells differentiate into various cell types, including Schwann cells, which produce the myelin sheaths that insulate axons in the peripheral nervous system.
