How does the posterior lobe of pituitary help in osmoregulation?

Text Solution

Verified by Experts

(a) Pituitary gland is commonly called "master gland" of the body because it regulates the activity of other endocrine glands such as adrenal gland, thyroid gland, testis and ovary
(b) The hypothalamus sends signals to the pituitary gland to release or inhibit pituitary hormone releasing factor production thus maintaining Homeostasis of the body.
(c) The posterior lobe of pituitary helps in osmoregulation by secreting the hormones namely vasopressin and oxytocin which increases tubular reabsorption of water in the nephrons.

    Read the given passage and answer the questions that follows: Rhodinus, a blood-sucking bug, shows five instars before it metamorphoses into an adult. It ahs a very long head with the brain located at tip and an organ called Corpora Cardiaca (C C) behind it. The hormone that ensures the continuum of the juvenile stages is called a juvenile hormone. Behind the head is a pro - thoracic gland, which gets triggered by the Pro - Thoracico - Tropic Hormone (PTTH) to release ecdysone required for molting into an adult. The following observations were made when the juveniles of this insect were subjected to various conditions : 1. Starved juveniles (any instar) when decapitated rarr remained juveniles and did not molt into adults. 2. Well-fed juveniles (any instar) when decapitated rarr molted into adults. 3. Starved juveniles (any instar) when partially decapitated to remove the brain cells rarr remained juveniles and did not molt into adults. 4. Well - fed juveniles (any instar) when partially deitated to remove the brain cells rarr did not molt into adults. If an unfed, completely decapitated, fth (final) instar juvenile is connected to a well-fed, decapitated fourth instar juvenile by a glass tube so that fluids can be exchanged, what whill be the expected result ?
