Question:
Which of the following hormone is secreted by neurohypophysis of pituitary gland?
Which of the following hormone is secreted by neurohypophysis of pituitary gland?
Show Hint
Think of the Neurohypophysis as a storage and release site. The key hormones stored here are nonapeptides: Vasotocin (Vasopressin equivalent) and Isotocin (Oxytocin equivalent) in fishes.
Updated On: Aug 20, 2026
- Prolactin
- Somatotropin
- Vasopressin
- Gonadotropin hormone
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
The pituitary gland (hypophysis) is divided into the adenohypophysis (anterior pituitary) and the neurohypophysis (posterior pituitary).
Step 2: Detailed Explanation:
- Adenohypophysis: Synthesizes and secretes hormones like Prolactin, Somatotropin (growth hormone), and Gonadotropins (GtH-I and GtH-II).
- Neurohypophysis: Does not synthesize hormones itself, but stores and secretes hormones synthesized in the hypothalamus. These include Vasopressin (antidiuretic hormone) and Oxytocin (and their teleost equivalents, arginine vasotocin and isotocin).
Step 3: Final Answer:
The hormone secreted by the neurohypophysis is Vasopressin, corresponding to option (C).
