The correct Answer is:
To answer the question "A hormone secreted from pituitary but not synthesized by pituitary is:", we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Structure of the Pituitary Gland**: - The pituitary gland is divided into two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). 2. **Identify the Functions of Each Part**: - The anterior pituitary synthesizes and secretes several hormones, including growth hormone, thyroid-stimulating hormone, prolactin, adrenocorticotropic hormone, follicle-stimulating hormone, and luteinizing hormone. - The posterior pituitary does not synthesize hormones; instead, it stores and releases hormones produced by the hypothalamus. 3. **Focus on the Posterior Pituitary**: - The posterior pituitary secretes two main hormones: vasopressin (also known as antidiuretic hormone, ADH) and oxytocin. 4. **Identify the Source of Synthesis**: - Both vasopressin and oxytocin are synthesized in the hypothalamus and then transported to the posterior pituitary for storage and release. 5. **Conclusion**: - Since the question asks for a hormone that is secreted by the pituitary but not synthesized by it, the correct answer is **vasopressin** (option B). ### Final Answer: The hormone secreted from the pituitary but not synthesized by it is **vasopressin**. ---
