What is a hyperfunctioning adenoma of the adrenal gland?

What is a hyperfunctioning adenoma of the adrenal gland?

Secretory: An adrenal adenoma usually does not produce the usual adrenal hormones (corticosteroids or mineralocorticoids) but if does, it is called hyperfunctioning. ...Read more

Pituitary Gland (Definition)

The pituitary is the source of several hormonal stimulation pathways, such as acth to stimulate the adrenal gland, TSH for the thyroid, but the posterior aspect deals with fluid and ...Read more

Does the adrenal gland affect the thyroid gland?

Does the adrenal gland affect the thyroid gland?

No: Both are stimulated by the anterior pituitary (tsh and acth), but don't necessarily affect each other;. ...Read more

Which organs do the pituitary gland influence?

Many: Breast, adrenal glands, thyroid glands, ovaries and testes, and kidneys, bones muscles, metabolism of the whole body blood pressure control and others. ...Read more

A deficiency in the release of vasopressin (antidiuretic hormone) by the posterior pituitary gland. Why?

A deficiency in the release of vasopressin (antidiuretic hormone) by the posterior pituitary gland. Why?

Possibly infarction: Possibly a tumor or something else. Lack of blood supply to the pituitary gland or a pituitary tumor may change the secretions of adh (vasopressin). However, there are other causes also, such as pregnancy that can cause this area to be infarcted (loss of blood supply). ...Read more

Can you explain the regulation of adrenal cortex function by the way of the pituitary gland stimulation of the adrena?

Can you explain the regulation of adrenal cortex function by the way of the pituitary gland stimulation of the adrena?

Feedforward/feedback: Hi. Hypothalamus important, but to keep it simple, pituitary ACTH stimulates the adrenal cortex to make cortisol. Cortisol negatively feeds back to suppress pituitary ACTH. If cortisol falls or a big stress is encountered, ACTH goes up and stimulates more cortisol production. The pituitary "sees" the increase in cortisol, and cuts back on ACTH to keep cortisol in appropriate range. Diurnal pattern ...Read more

Describe the function of the adrenal gland?

Describe the function of the adrenal gland?

Multifunctional: Very briefly, the adrenal gland can be divided between the cortex and medulla. The cortex makes a variety of hormones which control salt balance, cortisol, and androgens. The medulla primarily secretes norepinephrine and epinephrine. Functions of medulla and cortex are completely different as are the way their hormones are made and how they work. ...Read more

What can cause hyperplasia of the pituitary gland?

What can cause hyperplasia of the pituitary gland?

Pituitary: Are you reading a path report? Hyperplasia means proliferation of cells. Pituitary cells can do this for many reasons. Normal physiology, eg. lactating, pregnancy, growth spurt during teens. If you are hypothyroid, your pituitary will increase TSH -cells. Abnormal hormone production (prolactin, ACTH, GH) would involve hyperplasia. The path report must be correlated with the overall picture. ...Read more

What parts of the adrenal gland are controled by the pituitary gland? I read that there are three parts of the adrenal gland.

What parts of the adrenal gland are controled by the pituitary gland? I read that there are three parts of the adrenal gland.

The adrenal: cortex, or outer portion, is mostly controlled by the pituitary, and predominately produces cortisone, aldosterone and some sex hormones. The inner portion, or medulla, is regulated by blood pressure, nervous stimulation, emotions, etc. and produces epinephrine, norepinephrine and some other lesser hormones. ...Read more

Whats the role of the pituitary hormone follicle-stimulating hormone in males?

Whats the role of the pituitary hormone follicle-stimulating hormone in males?

Puberty & fertility: Regulates pubertal development & overall growth plus essential for fertility & sperm production.Fsh "matures" sperm producing cells in the testes. These cells, called spermatogonia, are stimulated to undergo meiotic division.This causes the full complement of 23 pairs chromosomes to split into 23 single chromosomes for the sperm nucleus.One of which is either an x or a y which determine fetal sex. ...Read more

Could you please describe hyperfunctioning adenoma of the adrenal gland?

Could you please describe hyperfunctioning adenoma of the adrenal gland?

Secreting hormones: Adrenal glands often get nodules/lumps/adenomas. They don't always secrete excess hormone. When they do, they can secrete aldosterone, norepinephrine, or cortisol. Each causes a syndrome: aldosteronoma, pheochromocytoma, cushing's. All include hypertension. If you have this, you should be seeing an endocrinologist. ...Read more

Cushing's syndrome: is pituitary gland removal the best form of treatment?

Cushing's syndrome: is pituitary gland removal the best form of treatment?

Cushing's Disease: Hi. Cushing's Disease is the pituitary tumor cause of Cushing's Syndrome (which can also be due to adrenal tumors, various cancers, or exogenous glucocorticoids). So for Cushing's Disease, yes, the first approach is almost always pituitary surgery (taking not whole gland, but only the tumor). Subsequent treatment depends on success of surgery, but can be more surgery, radiation, medications. ...Read more

What are the symptoms of kidney cysts or adrenal gland tumors?

What are the symptoms of kidney cysts or adrenal gland tumors?

Most times no sympto: Kidney cysts have no symptoms and are benign adrenal tumors most of the time are symptomless and non cancerous.Rarely there is adrenal cortex carcinoma and need treatment, it is quite rare.Can cause pain, treatment may include surgery, chemotherapy and/or radiation. ...Read more

Cortisol suppresses release of acth from the anterior lobe of the pituitary, what to do?

Cortisol suppresses release of acth from the anterior lobe of the pituitary, what to do?

Normal: Hi. Yes, that's the normal endocrine feedback loop to prevent the pituitary from secreting too much ACTH. What do you mean, "what to do"? I believe you WANT normal function. You haven't indicated any problem. Here's to your healthy, normal hypothalamic-pituitary-adrenal axis! ...Read more

Is the thyroxine balancing my pituitary gland?

Is the thyroxine balancing my pituitary gland?

Sort of: Thyroxine is made by the thyroid gland. Basically, the pituitary gland communicates with the thyroid gland via tsh, and the resulting secretion of normal concentrations of thyroxine in turn keep TSH in the normal range. The pituitary gland, however, secretes many more hormones aside from tsh. ...Read more

How harmful is cancer of the pituitary gland?

How harmful is cancer of the pituitary gland?

Extremely rare: However, any cancer that isn't treated by surgery, radiation or chemotherapy will eventually kill the person who has it. A pituitary adenoma and a craniopharyngioma (a dangerous benign tumor that arises near the pituitary) are both to be distinguished from cancer but both need to be managed. ...Read more

What hormone is released from the pituitary gland in females?

Many hormones: Lh (leutinizing hormone); fsh (follicular stim hormone); gh (growth hormone); TSH (thyroid stim hormone); acth (adrenocorticotropic hormone); prolactin. The posterior pituitary makes oxytocin and vasopressin. Men have the same hormones in pituitary; just different responses from the gonads. ...Read more
