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

Thyroid Gland (Definition)

It is an endocrine gland which produces thyroxin hormone which controls the metabolism in every cell in the body.It produces 80 to 90%t4 and 10 to 20 %t3. These control rate of metabolism and affect the growth and rate of functions of many cells in the body it is ...Read more

How do I differentiate the mandibular gland and lymph node? Is the gland directly above the neck pulse the mandibular gland?

How do I differentiate the mandibular gland and lymph node? Is the gland directly above the neck pulse the mandibular gland?

It may be hard.: You should be checked, you may have a difficult time discerning between a lymph node or the submandibular gland. If you can simultaneously palpate with one hand the floor of your mouth and the other hand your neck on the same side. You may be able to compress the gland between the two hands. That is one way to feel the submandibular gland. But if you are worried get checked. ...Read more

How are the adrenal gland and the thyroid connected?

How are the adrenal gland and the thyroid connected?

MEN II or Graves dis: In multiple endocrine neoplasia type ii patients can have medullary thyroid cancer and adrenaline secreting tumors. This is a rare familial syndrome. Thyroid hormone excess (graves or hyperthyroidism) makes patients more responsive to their own adrenaline. This why hyperthyroid patients are started on inderal, (propranolol) a beta blocker. ...Read more

In hyperthyroidism, if part of the thyroid is removed, does this decrease the thyroid hormone in the body?

In hyperthyroidism, if part of the thyroid is removed, does this  decrease the thyroid hormone in the body?

Depends on the cause: Depends on cause. Surgery for hyperthyroidism is either graves or hot nodule. Removing hot nodule will normalize thyroid levels. Surgery for graves is a total thyroidectomy and will require thyroid hormone replacement. ...Read more

Could my hypothalamus be giving orders to the adrenals to produce a surge of cortisol in response to my myasthenia gravis?

Could my hypothalamus be giving orders to the adrenals to produce a surge of cortisol in response to my myasthenia gravis?

Yes: The hypothalamus will stimulate the adrenals when there is any physical, mental or emotional stress. If the myasthenia is symptomatic, that is a stress and could stimulate the hypothalamus. ...Read more

Why would the thymus gland be enlarged and attached to the breast bone in  adult?   This was found on CT scan following chest pain shortness of breath

Thoracic Surgeon.: An "enlarged" thymus gland "attached to breast bone" with chest pain and shortness of breath, needs to be evaluated by an endocrinologist and possibly by a thoracic surgeon, the sooner the better. ...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

Could a chest X-ray see if the were a tumor between the ribs or the upper part of kidneys adrenal glands or strictly just the lungs?

Could a  chest X-ray see if the were a tumor between the ribs or the upper part of kidneys adrenal glands or strictly just the lungs?

The chest x-ray: Cn be very useful in experienced hands, but it is being fossilized by those that make exclusive use of ct's. The kidney and adrenal are below the diaphragm, and are obscured by the liver on the right and heart and spleen on the left. It is remotely possible that a chest x-ray might see a mass below the diaphragm in the locations you inquired. ...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

What are the effects of gamma knife radiation to the cavernous sinus cavity & pituitary gland due to an invasive atch secreting tumor?

What are the effects of gamma knife radiation to the cavernous sinus cavity & pituitary gland due to an invasive atch secreting tumor?

Possible scarring: Pituitary adenomas are nearly always benign tumors, but can be quite locally destructive or infiltrative, making them difficult to remove from all of the nooks and crannies of the region. Radiation provides a way of controlling the growth. Cavernous sinus isn't usually affected, although rare thrombosis can be seen. ...Read more

Can you tell me how the hypothalamus control the production and release of hormones of the pituitary gland?

Can you tell me how the hypothalamus control the production and release of hormones of the pituitary gland?

Nerve tracts: There are a set of nerve tracts from the hypothalamus that release hormones into the pituitary blood supply. The hormones are called "releasing hormones", and they cause the pituitary to release hormone. Eg. Hypothalamic TRH (thyrotropin releasing hormone) causes the pituitary to release TSH (thyroid stimulating hormone). ...Read more

Could masturbation act on the body like stimulants in that it taxes the adrenal glands?

Could masturbation act on the body like stimulants in that it taxes the adrenal glands?

Says who?: Somebody is feeding you a line of pure rubbish. If this actually happened, we pathologists would see people sick or dead just from enjoying themselves. We don't. Look at these people finishing the boston marathon. If this amount of emotional and physical stress is survivable and healthy, then when you do by yourself is nothing. You're an adult. Be discerning. Best wishes. ...Read more
