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

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

Mild enlargement of the right thyroid lobe without discrete nodules. There is a homogeneous appearance to the echotexture of the thyroid gland. ????

Mild enlargement of the right thyroid lobe without discrete nodules. There is a homogeneous appearance to the echotexture of the thyroid gland.  ????

Lobe enlarged: This should be of no significance if your thyroid hormone levels are all normal. There are no suspicious findings of benign or malignant growths. If you have further concerns a thyroidologist or endocrinologist would be best qualified to evaluate and advise you. ...Read more

Describe the normal action of the gland in hyperthyroidism?

Describe the normal action of the gland in hyperthyroidism?

Multiple organs...: The thyroid hormones secreted by the gland affects almost every system, including basal metabolism, skin, heart, brain, bowel. The thyroid gland is controlled by a part of the pituitary/hypothalamus gland in the brain in a feedback mechanism (as with all glands). Increased thyroid hormone can be associated with 'poppy' eyes, racy pulse, moist skin, perspiring, diarrhea. See prior answer. ...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 is the function of the adrenal gland in the body?

What is the function of the adrenal gland in the body?

Endocrine gland: The adrenal glands sit on top of the kidneys and their main function is to make hormones. The adrenal glands make hormones in response to stress (cortisol, epinephrine), hormones that affect kidney function and blood pressure (aldosterone), and sex hormones (androgens). These hormones circulate all around the body to affect the target organs and tissues. ...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

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

What's the thyroid vs. The parathyroid?

What's the thyroid vs. The parathyroid?

Anatomy: The thyroid gland is a major regulator of many functions of the body by producing thyroid hormones. It sits in the lower neck on both sides. The parathyroid glands regulate calcium metabolism. There are 4 of them and they lie behind (and often in contact with) the thyroid. ...Read more

Does the removal of thyroid nodes effects on the function of the brain?

Does the removal of thyroid nodes effects on the function of the brain?

Please define: Hi. There are thyroid nodules and lymph nodes, but not "thyroid nodes". However, removal of neither thyroid nodules nor lymph nodes will affect the function of the brain. Frankly that's kind of an off the wall question. Is there something particular you're thinking of? Good luck! ...Read more

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

What is the effect of HGH on the pituitary gland?

Negative feedback: The pituitary gland secretes many hormones and releasing factors, including growth hormone. Taking human growth hormone means that your internal servo control mechanism will be shut off. The pituitary cells will react as if they have made enough hormone, and so stop secreting. This may obligate you to continue replacement therapy, unless you already have a deficiency of growth hormone. ...Read more
