The release of hormones by the posterior pituitary is the result of what process?

A) Releasing hormones from the hypothalamus directs the production and release of oxytocin from the posterior pituitary.
B) Neurosecretory cells of the hypothalamus directly release hormones into blood vessels within the posterior pituitary.
