Anatomy of the Pituitary Gland The pituitary glands are made of the anterior lobe and posterior lobe. The anterior lobe produces and releases hormones. The posterior lobe does not produce hormones per se—this is done by nerve cells in the hypothalamus—but it does release them into the circulation.

How is the anterior pituitary gland different from the posterior pituitary gland?
The anterior pituitary receives signalling molecules from the hypothalamus, and in response, synthesizes and secretes seven hormones. The posterior pituitary does not produce any hormones of its own; instead, it stores and secretes two hormones made in the hypothalamus.
Which is a difference between the anterior pituitary and the posterior pituitary quizlet?
The anterior pituitary arises from a pouch that grows upward from the embryonic pharynx, while the posterior pituitary arises as a bud growing downward from the brain.
How do the cells of the anterior pituitary and posterior pituitary differ in appearance?
There are more cells in the anterior pituitary, so it usually stains darker. While the anterior pituitary (a) is made up almost entirely of cells, the posterior pituitary (p) contains few cells and a lot of nerve cell processes--the axons of hypothalamic neurons.
What is the main function of the posterior pituitary gland?
Posterior Pituitary Hormones
The primary function of the posterior pituitary is the transmission of hormones originating from neurons located in hypothalamic brain regions such as the supraoptic nucleus (SON) and paraventricular nucleus (PVN) for secretion directly into peripheral circulation.
What are the 7 hormones of the anterior pituitary gland?
The anterior pituitary gland produces six major hormones: (1) prolactin (PRL), (2) growth hormone (GH), (3) adrenocorticotropic hormone (ACTH), (4) luteinizing hormone (LH), (5) follicle-stimulating hormone (FSH), and (6) thyroid-stimulating hormone (TSH) (Table 401e-1).
Does the posterior pituitary produce hormones?
The posterior lobe of the pituitary produces only two hormones: Vasopressin. Oxytocin.
Why is the anterior pituitary called the master gland?
Anatomy of the pituitary gland
The pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain.
How is the posterior pituitary gland connected to the hypothalamus?
In contrast, the posterior lobe is connected to the hypothalamus by a bridge of nerve axons called the hypothalamic–hypophyseal tract, along which the hypothalamus sends hormones produced by hypothalamic nerve cell bodies to the posterior pituitary for storage and release into the circulation.
What hormone stimulates the kidneys to reabsorb water as urine is being formed?
Water levels in the body are controlled by antidiuretic hormone (ADH), which is produced in the hypothalamus and triggers the reabsorption of water by the kidneys.
Are the following hormones released by the anterior or posterior pituitary?

Where is the posterior pituitary located?
The posterior pituitary (neurohypophysis) is a downgrowth from the base of the brain and is connected with the hypothalamus by neurons.
