What kind of tissue is posterior pituitary?
The posterior pituitary gland is composed of nervous tissue. It stores and releases hormones produced by the hypothalamus, such as oxytocin and vasopressin, into the bloodstream.
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).
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.
What are the main differences between the posterior and anterior pituitary glands in terms of their functions and hormone secretion?
The main differences between the posterior and anterior pituitary glands are in their functions and hormone secretion. The posterior pituitary mainly stores and releases hormones produced by the hypothalamus, such as oxytocin and vasopressin, while the anterior pituitary produces and releases its own hormones, including growth hormone, thyroid-stimulating hormone, and adrenocorticotropic hormone.
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.
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.

The anterior pituitary is derived from glandular tissue, while the posterior pituitary originates from neural tissue.
Does the posterior pituitary gland synthesize oxytocin?
No, the posterior pituitary gland does not synthesize oxytocin. Instead, it stores and releases oxytocin, which is produced in the hypothalamus and transported to the posterior pituitary gland for storage and eventual release in response to certain stimuli.
Does the pituitary gland have glandular and neural tissue?
Yes, the pituitary gland is composed of both glandular and neural tissue. The anterior pituitary is primarily glandular and produces and releases hormones, while the posterior pituitary is neural tissue that stores and releases hormones produced by the hypothalamus.

Is the posterior pituitary gland a true endocrine gland?
Yes, the posterior pituitary gland is considered a true endocrine gland because it produces and releases hormones into the bloodstream. It stores and releases hormones such as oxytocin and antidiuretic hormone that are produced by the hypothalamus.
Does the posterior pituitary gland respond to the gonadotropin-releasing hormone?
No, the posterior pituitary gland does not respond to gonadotropin-releasing hormone (GnRH). The posterior pituitary mainly secretes oxytocin and vasopressin, which are produced in the hypothalamus and stored in the posterior pituitary before being released into the bloodstream. GnRH primarily acts on the anterior pituitary gland to regulate the release of gonadotropins like luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Where is the posterior pituitary gland located?
The posterior pituitary is located in a portion of the sphenoid bone called the sella turcica. It is attached to the anterior pituitary gland by the pars intermedia which is a thin layer of endocrine tissue. The posterior pituitary is actually just an extension of the neural tissue that composes the hypothalamus.
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.
