Answer
Posterior pituitary
Explanation
Solution
Secretion of posterior pituitary is under neurosecretory nerve axons. Neurosecretory neurons are glandular, unmyelinated secretory cells with two functions. One of which is to synthesize and release neurohormones either directly into the general circulation (as in the case of neurosecretory neurons of the pars nervosa) or into a portal system.
