• vesicles
  • It then travels down the axon of that cell, which terminates in the posterior pituitary, and is released from vesicles into the circulation in response to extracellular fluid hypertonicity (hyperosmolality). (wikipedia.org)
  • stalk
  • Infundibular stalk Also known as the infundibulum or pituitary stalk, the infundibular stalk bridges the hypothalamic and hypophyseal systems. (wikipedia.org)
  • The median eminence is part of the inferior boundary of the hypothalamus in the human brain that is attached to the infundibulum (a.k.a. the pituitary stalk). (wikipedia.org)
  • thyrotropin
  • One example of abnormal stimulation that leads to endocrine hyperfunction is Graves disease , which is characterized by the production of antibodies that bind to and stimulate the receptors for thyrotropin in the thyroid gland . (britannica.com)
  • abnormal
  • If venous congestion is the primary cause of pituitary gland enlargement in cases of dural arteriovenous fistulas (AVFs), other abnormal pituitary findings may be detectable on MR images. (ajnr.org)
  • If we think of the venous congestion as the primary cause of the pituitary gland enlargement, other additional abnormal findings in the pituitary gland could possibly be detected on MR images. (ajnr.org)
  • secondary
  • In contrast, patients diagnosed with secondary parathyroid hyperplasia have decreased serum calcium concentrations, resulting in stimulation of the parathyroid glands to produce more parathormone in an attempt to restore serum calcium concentrations to normal. (britannica.com)
  • cells
  • In some instances, some of the cells of a hyperplastic gland undergo a series of transformations that results in the formation of a tumour . (britannica.com)
  • body
  • It is released from the posterior pituitary in response to hypertonicity and causes the kidneys to reabsorb solute-free water and return it to the circulation from the tubules of the nephron, thus returning the tonicity of the body fluids toward normal. (wikipedia.org)
