Question:
Which hypothalamic hormones directly act on kidney tubules and uterus respectively?
Which hypothalamic hormones directly act on kidney tubules and uterus respectively?
Show Hint
ADH (vasopressin) acts on the kidney and oxytocin acts on the uterus.
Updated On: Nov 13, 2026
- Vasopressin and GnRH
- Vasopressin and Adreno Corticotropin releasing hormone.
- Vasopressin and oxytocin
- Oxytocin and Adreno corticotropin releasing hormone
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
The hypothalamus makes vasopressin (ADH) and oxytocin, which are released through the posterior pituitary.
Step 2: Kidney Action
Vasopressin acts on the distal tubules and collecting ducts of the kidney and increases water reabsorption.
Step 3: Uterus Action
Oxytocin makes the smooth muscles of the uterus contract during childbirth.
So the pair is vasopressin and oxytocin.
Final Answer:
Vasopressin acts on kidney tubules and oxytocin acts on the uterus. \[ \boxed{\text{(C) }\text{Vasopressin and oxytocin}} \]
