Pars nervosa
Herring bodies are expanded axon terminals of supraoptic and paraventricular hypothalamic neurons. Herring bodies are primarily located in the pars nervosa and are filled with secretory granules containing the hormones vasopressin or oxytocin. Herring bodies are variously sized, eosinophilic, and oval to spherical in shape. 400x
