Cardiac muscle, like skeletal …Striated (skeletal) muscles throughout the body arise within paraxial mesoderm, which is located in close apposition to the embryonic brain and spinal cord. Exceptions to this are the avian striated ciliary muscle that is of neural crest origin, and possibly the striated muscles of the esophageal wall; however, both of these are involuntary.Cardiac muscle is a type of tissue that develops from the mesoderm during embryonic development. It develops from the cells of the primitive heart tube, aligns into chain like arrays, and has the same arrangement of its contractile filaments as seen in skeletal muscle. As the name suggests, cardiac muscle is only found in the heart.
