WebThe skin is innervated by two types of nerve fibers, sensory and autonomic. Nerve fibers innervating the skin originate from dorsal root ganglia nerve cell bodies of sensory nerves (Hsieh et al., 1997 ). At E13–E14 the sensory nerves elongate from the dorsal root ganglion and migrate toward the skin. At E15.5, nerve fibers are detected in the ...
