Does anyone know if blood vessels contain nerve tissue?

  • body structures - ,

    Since headaches result from changes in cerebral blood vessels, I assume it is likely that at least these vessels either contain nerve tissue or stimulate nerve tissue surrounding them. I do know that nerves in the autonomic system are responsible for constricting or dilating blood vessels.

    However, this is not my area of expertise.

    I hope this helps. Thanks for asking.
