explain Pitutiary gland in detail
Answers
Pituitary gland:
the body’s master gland; located at the base of the brain and attached to the hypothalamus via a stalk called the pituitary stalk;
has two distinct regions: the anterior portion of the pituitary gland is regulated by releasing or release-inhibiting hormones produced by the hypothalamus,
and the posterior pituitary receives signals via neurosecretory cells to release hormones produced by the hypothalamus.
Hormones produced (or secreted) by the gland include:
Anterior pituitary:
the following hormones are produced by the anterior pituitary and released in response to hormone signals from the hypothalamus.
Growth hormone:
stimulates growth factors
Adrenocorticotropic hormone (ACTH):
simulates adrenal glands to secrete glucocorticoids such as cortisol
thyroid-stimulating hormone: stimulates thyroid gland to secrete thyroid hormones.
Follicle-stimulating hormone (FSH) and Luteinizing hormone (LH):
stimulates production of gametes and sex steroid hormones.
Prolactin:
stimulates mammary gland growth and milk production.
Posterior pituitary:
the following hormones are produced by the hypothalamus and stored in the posterior pituitary.

here is your answer...
The pituitary gland is a tiny organ, the size of a pea, found at the base of the brain. As the “master gland” of the body, it produces many hormones that travel throughout the body, directing certain processes or stimulating other glands to produce other hormones.The pituitary gland makes or stores many different hormones.
Symptoms of a pituitary gland:
Your pituitary gland is involved in a range of things, so any condition involving it can produce a diverse set of symptoms.
Make an appointment with your doctor if you regularly notice:
> headaches
>weakness or fatigue
>high blood pressure
>unexplained weight gain
>trouble sleeping
>changes in psychological state, including mood swings or depression
>memory loss
>reproductive issues, including infertility, erectile dysfunction, and irregular periods
>excessive or unusual hair growth
>lactating when you’re not nursing
Most of the conditions that cause these symptoms are easy to treat and manage once you determine the underlying cause.
Examples of pituitary gland disorders include:
>>Pituitary tumors. Pituitary tumors are usually noncancerous. However, they often interfere with the release of hormones. They can also press against other areas of your brain, leading to vision problems or headaches.
>>Hypopituitarism. This condition causes your pituitary gland to produce very little or none of one or more of its hormones. This can affect things like growth or reproductive system function.
>>Acromegaly. In this condition, your pituitary gland produces too much growth hormone. This can lead to excessive growth, especially of your hands and feet. It’s often associated with pituitary tumors.
>>Diabetes insipidus. This can be caused by a problem with the release of vasopressin. It’s usually due to a head injury, surgery, or a tumor. As a result, people with this condition pass large amounts of heavily diluted urine. They may also feel like they need to drink a lot of water or other fluids.
>>Cushing’s disease. The pituitary gland releases too much adrenocorticotropic hormone in people with this condition. This can lead to easy bruising, high blood pressure, weakness, and weight gain. It’s often caused by a tumor near or in the pituitary gland.
>>Hyperprolactinemia. In this condition, your blood contains an unusually high amount of prolactin. This can lead to infertility and a decreased sex drive.
>>Traumatic brain injury. This involves a sudden blow to your brain. Depending on the injury, it can sometimes damage your pituitary gland and cause problems with memory, communication, or behavior.
