Summary Introduction

Introduction:

The pituitary consists of the anterior pituitary and posterior pituitary, which differ by their origin and functions. The anterior lobe or adenohypophysis of the pituitary is derived from the invagination of the oral ectoderm. Based on nerve signals, the hypothalamus secretes hormones, which stimulate or inhibit the production of hormones by the anterior pituitary. The anterior pituitary synthesizes and secretes endocrine hormones such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), prolactin, growth hormone (GH), and thyroid-stimulating hormone (TSH). The anterior pituitary hormones regulate metabolism, growth, and reproduction and also regulate other endocrine glands and tissues.
