Question

A blow to the head may cause diabetes insipidus by ______. A blow to the head may cause diabetes insipidus by ______. triggering the hypersecretion of hypothalamic-inhibiting hormones triggering the hyposecretion of hypothalamic-inhibiting hormones interfering with the normal transmission of nerve impulses to the posterior pituitary interfering with the normal transmission of nerve impulses from the posterior pituitary

Answer 1

Answer: interfering with the normal transmission of nerve impulses to the posterior pituitary

Explanation: A blow to the head may cause diabetes insipidus by interfering with the normal transmission of nerve impulses to the posterior pituitary. Interfering with the normal transmission of ADH (antidiuretic hormone) to the posterior pituitary is done via the axons of the hypothalamic neurons. The disease is a rare one, characterized by the excretion of large amounts of severely diluted urine which cannot be reduced when fluid intake is reduced. It is generally related to a tumor or an insult to the pituitary gland, where the hormonal signals it gives to the kidneys break down, and the kidneys do not conserve water, but express the water as urine.
