  2. Neurosecretion - Wikipedia

    en.wikipedia.org/wiki/Neurosecretion

    As more became known about neurosecretory cells, the difference between the actions of nerve communication and endocrine hormone release become less clear. Like the average neuron, these cells conduct electrical impulses along the axon but unlike these neurons, neurosecretion produces neurohormones that are released into the body’s circulation.

  3. Magnocellular neurosecretory cell - Wikipedia

    en.wikipedia.org/wiki/Magnocellular...

    Magnocellular neurosecretory cells in rats (where these neurons have been most extensively studied) in general have a single long varicose axon, which projects to the posterior pituitary. Each axon gives rise to about 10,000 neurosecretory terminals and many axon swellings that store very large numbers of hormone-containing vesicles. [3]

  4. Parvocellular neurosecretory cell - Wikipedia

    en.wikipedia.org/wiki/Parvocellular...

    Parvocellular neurosecretory cells are small neurons that produce hypothalamic releasing and inhibiting hormones. The cell bodies of these neurons are located in various nuclei of the hypothalamus or in closely related areas of the basal brain, mainly in the medial zone of the hypothalamus.

  5. Herring bodies - Wikipedia

    en.wikipedia.org/wiki/Herring_bodies

    Herring bodies or neurosecretory bodies are structures found in the posterior pituitary. They represent the terminal end of the axons from the hypothalamus , and hormones are temporarily stored in these locations.

  6. Supraoptic nucleus - Wikipedia

    en.wikipedia.org/wiki/Supraoptic_nucleus

    Each neuron in the nucleus has one long axon that projects to the posterior pituitary gland, where it gives rise to about 10,000 neurosecretory nerve terminals. The magnocellular neurons are electrically excitable: In response to afferent stimuli from other neurons, they generate action potentials, which propagate down the axons. When an action ...

  7. Paraventricular nucleus of hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Paraventricular_nucleus_of...

    The axons of the parvocellular neurosecretory neurons of the PVN project to the median eminence, a neurohemal organ at the base of the brain, where their neurosecretory nerve terminals release their hormones at the primary capillary plexus of the hypophyseal portal system. The median eminence contains fiber terminals from many hypothalamic ...

  8. Neurohypophysial hormone - Wikipedia

    en.wikipedia.org/wiki/Neurohypophysial_hormone

    Most of the circulating oxytocin and vasopressin hormones are synthesized in magnocellular neurosecretory cells of the supraoptic nucleus and paraventricular nucleus of the hypothalamus. They are then transported in neurosecretory granules along axons within the hypothalamo-neurohypophysial tract by axoplasmic flow to axon terminals forming the ...

  9. Posterior pituitary - Wikipedia

    en.wikipedia.org/wiki/Posterior_pituitary

    The posterior pituitary consists mainly of neuronal projections of magnocellular neurosecretory cells extending from the supraoptic and paraventricular nuclei of the hypothalamus. These axons store and release neurohypophysial hormones oxytocin and vasopressin into the neurohypophyseal capillaries, from there they get into the systemic ...
