What happens if posterior pituitary is damaged?
Posterior pituitary injury results in loss of hypothalamic control of Antidiuretic Hormone (ADH) release. This can result in: Excess release or Syndrome of Inappropriate Antidiuretic Hormone (SIADH) with low sodium levels (hyponatraemia).
What causes posterior pituitary?
Ectopic posterior pituitary is associated with the under-production of growth hormone and in some cases with the under-production of all pituitary hormones (panhypopituitarism). It can be associated with other pituitary conditions, including septo-optic dysplasia and Kallmann syndrome.
What diseases are associated with the pituitary gland?
Pituitary tumors causing hormonal excess are called functioning pituitary tumors. Acromegaly, Cushing’s disease and prolactinomas are the most common.
What happens if your pituitary gland isn’t working properly?
For example, if the pituitary gland does not produce enough growth hormone in a child, they may have a permanently short stature. If it doesn’t produce enough follicle-stimulating hormone or luteinizing hormone, it might cause problems with sexual function, menstruation, and fertility.
What stimulates the release of ADH from the posterior pituitary gland?
In response to high blood osmolarity, which can occur during dehydration or following a very salty meal, the osmoreceptors signal the posterior pituitary to release antidiuretic hormone (ADH).
What are the functions of posterior pituitary gland?
Posterior pituitary: The back portion of the pituitary, a small gland in the head called the master gland. The posterior pituitary secretes the hormone oxytocin which increases uterine contractions and antidiuretic hormone (ADH) which increases reabsorption of water by the tubules of the kidney.
What hormones come from posterior pituitary?
The posterior lobe produces two hormones, vasopressin and oxytocin. These hormones are released when the hypothalamus sends messages to the pituitary gland through nerve cells. Vasopressin is also known as antidiuretic hormone (ADH).
What is unique about the posterior pituitary?
The posterior pituitary is derived from the hypothalamus and is distinct from the more fleshy, vascularized anterior lobe. … The pars nervosa, also called the neural lobe or posterior lobe, constitutes the majority of the posterior pituitary and is the storage site of oxytocin and vasopressin.
Why posterior pituitary is called Neurohypophysis?
The posterior pituitary is nervous tissue, hence the name neurohypophysis. It originates as an outgrowth from the diencephalic region that will become the hypothalamus. The neurohypophysis consists of the terminals of axons extending down through the stalk from cell bodies in the hypothalamus.

Is there a blood test for pituitary function?
Blood tests help doctors detect many hormonal abnormalities associated with pituitary tumors. For example, a blood test can reveal high levels of the hormone prolactin, which occurs in a condition called hyperprolactinemia. This can indicate the presence of a pituitary tumor called a prolactinoma.
How do you fix a pituitary gland problem?
