The incorrect statement is option 'A': Hypothalamus is exocrine Glands.

The hypothalamus is a small but crucial part of the brain that plays a significant role in regulating various bodily functions. It is located just above the pituitary gland at the base of the brain. While the hypothalamus does not directly function as an exocrine gland, it does have a complex relationship with the pituitary gland and plays a vital role in regulating the release of hormones.

The correct statements are:

b) Hypothalamus affects the release of hormones from the pituitary:
The hypothalamus acts as a link between the nervous system and the endocrine system. It produces and releases various hormones that control the secretion of hormones from the pituitary gland. These hormones are called releasing hormones or inhibiting hormones and include substances like thyrotropin-releasing hormone (TRH), corticotropin-releasing hormone (CRH), and gonadotropin-releasing hormone (GnRH). The hypothalamus releases these hormones into the hypothalamic-pituitary portal system, a network of blood vessels that connects the hypothalamus and the pituitary gland. This system allows the hypothalamus to directly influence the release of hormones from the pituitary gland.

c) Pituitary Gland is also called the Master Gland:
The pituitary gland, often referred to as the "master gland," is a small pea-sized gland located at the base of the brain, just below the hypothalamus. It is called the master gland because it controls and regulates the functions of many other endocrine glands in the body. The pituitary gland produces and releases several important hormones that play a critical role in growth, metabolism, reproduction, stress response, and other bodily functions. It receives signals from the hypothalamus and responds by releasing appropriate hormones into the bloodstream, which then act on target organs or other endocrine glands to regulate their activities.

d) None of the above:
This statement is incorrect because, as explained above, option 'A' is the incorrect statement. Both options 'B' and 'C' are correct. The hypothalamus does affect the release of hormones from the pituitary gland, and the pituitary gland is often referred to as the master gland due to its regulatory role in the endocrine system.

Therefore, the correct answer is option 'A': Hypothalamus is exocrine Glands.
