Summary Introduction

Introduction:

The posterior pituitary or posterior lobe is an extension of the hypothalamus nervous tissues, and it is not a true gland. The hypothalamus communicates with the posterior pituitary through hypothalamo-hypophyseal tract. The posterior pituitary hormones namely antidiuretic hormone (ADH) and oxytocin are synthesized by neurosecretory cells located in the hypothalamus. Then, these hormones travel and store in the posterior pituitary. The posterior pituitary hormones will be released when they receive the response or signals from the hypothalamus. The posterior pituitary hormones regulate water retention by the kidney and reproduction.
