The posterior pituitary gland only produces two hormones. It produces antidiuretic hormone (vasopressin) and oxytocin.

What are the two sections of the pituitary?

The pituitary gland is divided into two sections: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). The anterior pituitary produces and releases hormones that regulate various physiological processes, while the posterior pituitary stores and releases hormones produced by the hypothalamus.


What is hypothalamus and the posterior pituitary are joined by?

The hypothalamus and the posterior pituitary are joined by the pituitary stalk, also known as the infundibulum. This structure allows for communication between the hypothalamus and the posterior pituitary gland, enabling the release of hormones like oxytocin and vasopressin into the bloodstream.


What is the function of the posterior pituitary gland?

The posterior pituitary is made up of axons belonging to cells called neurosecretory cells, whose cell bodies are in the hypothalamus. When these cell bodies are stimulated, the axons in the posterior pituitary releases their hormones into the blood stream. In a way, the posterior pituitary is an extension of the hypothalamus.


What pair of hormones are not synthesized in the anterior pituitary gland?

ADH or anti-diuretic hormone and oxytocin are synthesized by posterior pituitary and not anterior pituitary gland.


The hormones stored in the posterior pituitary are released only when triggered by the what?

The hormones stored in the posterior pituitary gland, such as oxytocin and vasopressin, are released in response to nerve signals from the hypothalamus. These hormones are only released when specific stimuli trigger their release, such as childbirth or changes in blood osmolarity.

How does the anterior and posterior pituitary differ?

The anterior pituitary produces and secretes its own hormones in response to releasing hormones from the hypothalamus, while the posterior pituitary stores and releases hormones produced by the hypothalamus. The anterior pituitary is derived from glandular tissue, while the posterior pituitary originates from neural tissue.


How the two hormones arrive in the posterior pituitary?

Oxytocin and vasopressin are synthesized in the hypothalamus and transported to the posterior pituitary through nerve fibers known as hypothalamic-hypophyseal tract. These hormones are then stored in the nerve terminals until they are released into the bloodstream in response to appropriate signals or stimuli.


What is the function of the posterior lobe of the pituitary gland?

The function of the posterior lobe of the pituitary gland is to store and secrete hormones that are produced by the brain. These hormones are oxytocin and antidiuretic hormone.


The posterior pituitary gland is not made of glandular tissue?

Correct, the posterior pituitary gland is mostly composed of nerve tissue, specifically axons and nerve endings. It stores and releases hormones produced by the hypothalamus, but it does not manufacture its own hormones like the anterior pituitary gland does.

Can the hypothalamus function without the pituitary?

No, because the hypothalamus manufactures the hormones for the posterior pituitary gland and it sends the instructions for the anterior pituitary gland to produce hormones.


What hormones are synthesized by the posterior pituitary gland?

The posterior pituitary gland stores and releases two hormones synthesized by the hypothalamus: oxytocin and vasopressin (antidiuretic hormone).


What are Oxytocin and ADH secreted by?

The posterior lobe of the pituitary gland in the brain.

What are the two lobes of the pituitary gland?

The pituitary gland is connected to the hypothalamus by a small stalk. The interaction between the nervous system and endocrine is evident in this hypothalamus-pitutary complex. The pituitary gland produces and stores hormones. The hypothalamus simulate the release of hormones by the pituitary gland by way of nerves.The pituitary gland consist of two lobes. The posterior lobe stores and releases hormones, such as ADH and oxytocin. The anterior lobe of the pituitary gland produces its own hormone. It is richly supplied with nerves from the hypothalamus.

The posterior pituitary is made up of axons belonging to cells called neurosecretory cells, whose cell bodies are in the hypothalamus. When these cell bodies are stimulated, the axons in the posterior pituitary releases their hormones into the blood stream. In a way, the posterior pituitary is an extension of the hypothalamus.
