The Pituitary Gland and Hypothalamus Biology Diagrams The hypothalamus-pituitary complex can be thought of as the "command center" of the endocrine system. This complex secretes several hormones that directly produce responses in target tissues, as well as hormones that regulate the synthesis and secretion of hormones of other glands.
Adrenocorticotropic Hormone (ACTH) The major role of ACTH is to stimulate the formation of steroid hormones in the adrenal gland, such as cortisol. Corticotrophs are cells that produce ACTH and make up 10% to 20% of the anterior lobe. Cortisol secretion is regulated by the hypothalamic-pituitary-adrenal axis.
Pituitary Gland: What It Is, Function & Anatomy Biology Diagrams
The hormones secreted by the pituitary gland are vital regulators of most of the other endocrine glands. In addition, some hormones directly control the function of specific organs.
What is Pituitary Gland? Definition of Pituitary Gland. The pituitary gland is an endocrine gland that works to maintain cellular homeostasis in the body by the release of different hormones.. The pituitary gland is also called the master gland as it regulates the working and secretion of other endocrine glands. The pituitary hormones are special chemical messengers that are produced by the pituitary gland, also known as "the master gland of the body." The hormones are peptides or glycoproteins in nature and play a vital role in regulating the functions of other endocrine glands. The anterior pituitary hormones are produced by five different endocrine cell types (somatotropes, gonadotropes
Definition, Anatomy, Hormones, & Disorders - Britannica Biology Diagrams
The pituitary gland consists of an anterior and posterior lobe, with each lobe secreting different hormones in response to signals from the hypothalamus. The hypothalamus is a neuroendocrine structure within the diencephalon, positioned anteriorly and inferiorly to the thalamus (Figure 11). Hormone Secretion by the Anterior Pituitary .
