  2. Posterior pituitary - Wikipedia

    en.wikipedia.org/wiki/Posterior_pituitary

    The posterior pituitary is not glandular as is the anterior pituitary. Instead, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary, and serve as a site for the secretion of neurohypophysial hormones ( oxytocin and vasopressin ) directly into the blood. [ 2 ]

  3. Pituicyte - Wikipedia

    en.wikipedia.org/wiki/Pituicyte

    They may be mistaken for the much more common pituitary adenoma, as well as craniopharyngioma and meningioma. Symptoms from the mass effect of the tumor usually include vision disorders, and less often headaches, hypopituitarism (decreased function of the pituitary gland), fatigue, and decreased libido.

  4. 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. They are neurosecretory terminals. [1]

  5. Supraoptic nucleus - Wikipedia

    en.wikipedia.org/wiki/Supraoptic_nucleus

    The oxytocin and vasopressin that is released at the posterior pituitary gland enters the blood, and cannot re-enter the brain because the blood–brain barrier does not allow oxytocin and vasopressin through, but the oxytocin and vasopressin that is released from dendrites acts within the brain. Oxytocin neurons themselves express oxytocin ...

  6. Autoimmune hypophysitis - Wikipedia

    en.wikipedia.org/wiki/Autoimmune_hypophysitis

    Autoimmune hypophysitis can lead to deficiencies in one or more pituitary hormones, causing central diabetes insipidus if the posterior pituitary gland is affected as well as central adrenal insufficiency and central hypothyroidism if the anterior pituitary gland is affected. [1] The symptoms depend on what part of the pituitary is affected.

  7. Magnocellular neurosecretory cell - Wikipedia

    en.wikipedia.org/wiki/Magnocellular_neuro...

    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 ]

  8. Inferior hypophysial artery - Wikipedia

    en.wikipedia.org/wiki/Inferior_hypophysial_artery

    The inferior hypophysial artery is a branch of the cavernous carotid artery, itself from the internal carotid artery. [1] [2] Alternatively, it may arise from the meningohypophyseal artery. [3]

  9. Pituicytoma - Wikipedia

    en.wikipedia.org/wiki/Pituicytoma

    It grows at the base of the brain from the pituitary gland. This tumor is thought to be derived from the parenchymal cells of the posterior lobe of the pituitary gland, called pituicytes. Some researchers [1] believe that they arise from the folliculostellate cells in the anterior lobe of the pituitary. As such, it is a low-grade glioma.
