What are the functions of the endocrine system?
The endocrine system is one of the most important systems that govern the body. Acting with the nervous system, it helps coordinate and integrate the activity of the body's cells.
It consists the glands that produce the hormones.
The major functions of the endocrine system are:
~it regulates the metabolic functions of the body
~regulates the rate of chemical reactions in various cells
~influences the ability of substances to transport themselves through cell membranes
The endocrine system main function is to create and make work the glands.
The endocrine system produces chemicals that control many of the body's daily activities. The endocrine system also regulates long-term changes such as growth and development.
The thyroid is a gland situated in the neck area that secretes hormones. Thyroxin is a hormone that is released by the thyroid gland, along with iodothyronin and calcitonin.
Who invented Synthroid thyroid medicine?
Synthroid is currently manufactured by Abbott Laboratories but was originally isolated by Mayo Clinic. Currently there are generic products on the market that are made by various manufacturers as well
Why are there different hormones in men and women?
because they need different for different parts of a male and female's body.
Adrenaline and noradrenaline hormones are secreted in stress conditions. During this the blood vessels dilates and the heart rate increases. BUT actually the function of both the hormone is synergistic in raising the blood pressure. These also release glucose from liver and reinforce the effects of sympathetic system. In the absence of these hormones, the stress conditions are diminished.
List the cardinal symptoms of diabetes mellitus?
Diabetes Mellitus comes in two common forms, Insulin-Dependent Diabetes Mellitus (or Type 1 Diabetes) and Non-Insulin-Dependent Diabetes Mellitues (Type 2 Diabetes). (There is also Gestational Diabetes which occurs during pregnancy).
Type 1 diabetes is an autoimmune disease mainly found in children. In this type of diabetes the child's immune system attacks insulin producing cells found in the pancreas. Insulin is a hormone that raises blood sugar.
Type 2 diabetes is due to diet and age. This form of diabetes is traditionally found in older individuals, but we often hear about the rise of diabetes in younger people. In this case the body is worn down and organs, especially the pancreas and liver, are not able to regulate blood sugar as effectively.
The symptoms of both forms of diabetes are the same. The person will experience excessive thirst and hunger, weight loss, frequent urination, and fatigue. The excessive thirst is due to dehydration. The blood glucose (sugar) is increased and the individual will have a high amount of glucose in their urine (giving it a sweet smell) causing them to loose more water. Glucose in the urine can also cause more bladder infections. Due to the high amounts of blood sugar they may experience blurry vision and lethargy.
Where is thyroid stimulating hormone TSH synthesized?
it is produced in the anterior pituitary gland, which stimulates the release of thyroxine form the thyroid gland
What does the endocrine system release in the blood stream?
Endocrine glands release hormones. These chemical messengers control body processes.
Where are your endocrine glands?
Your endocrine gland is consist of a system of glands with the main glands called the pituitary gland, pancreas, ovaries and testes, thyroid gland, and the adrenal glands.
How do substances made by endocrine glands get to other parts of the body?
endocrine glands reach their target organs because the secretion go directly to the bloodstream unlike exocrine glands that have ducts, endocrine glands secretes hormones that mix with the blood

What is the danger of having high blood calcium levels?
Hypercalcemia, high amounts of calcium in the blood, has symptoms such as nausea, vomiting, bone pain, dementia, and weakness.
Hypercalcemia is commonly caused by improper function of the parathyroid glands.
How do the endocrine glands affect growth and development?
It produces hormones that help us to grow and develop.
Which endocrine gland produces the hormone ADH?
It is called antidiuretic hormone.It controls the urine volume mainly
What are Two hormones produced by the endocrine system?
The Pituitary gland "the master gland" produces: FSH, LH, ACTH, TH, Prolatin, GH, Oxytocin, ADH and MSH.
There are many more hormones produced by the endocrine system, these are the ones produced from the "master gland"
What hormone is released into the blood when the body loses fluid?
When your body loses fluids it alters your blood pressure sending signals to your brain telling it that your BP is too low. This sends off signals to your body to try and compensate. ADH (anti-diuretic hormone) is released and prevents fluid to be excreted by the kidneys into your urine. This raises the blood pressure back up by increasing the water within it. This doesn't increase your RBCs or platelets but it just allows your blood volume to remain at a relatively normal level.
It's the anti-diuretic hormone.
What hormones does the pituitary gland release to control other endocrine glands?
The anterior pituitary synthesizes and secretes the following important endocrine hormones:
Adrenocorticotropic hormone (ACTH), release under influence of hypothalamic Corticotropin Releasing Hormone (CRH).
Thyroid-stimulating hormone (TSH), release under influence of hypothalamic Thyrotropin Releasing Hormone (TRH).
Growth hormone (also referred to as 'Human Growth Hormone', 'HGH' or 'GH' or somatotropin), release under influence of hypothalamic Growth Hormone Releasing Hormone (GHRH); inhibited by hypothalamic Somatostatin.
Prolactin (PRL), also known as 'Luteotropic' hormone (LTH), release under influence of multiple hypothalamic Prolactin Releasing Factors (PRH).
The two 'Gonadotropins';
Luteinizing hormone (also referred to as 'Lutropin' or 'LH', or in males, 'Interstitial Cell Stimulating Hormone' (ICSH)), and
Follicle stimulating hormone (FSH), both released under influence of Gonadotropin Releasing Hormone (GnRH).
and;
melanocyte-stimulating hormones (MSH's) or "intermedins" as these are released by the pars intermedia which is "the middle part"; adjacent to the posterior pituitary lobe, pars intermedia is a specific part developed from the anterior pituitary lobe.
The posterior pituitary stores and releases:
Oxytocin, most of which is released from the paraventricular nucleus in the hypothalamus
Antidiuretic hormone (ADH, also known as vasopressin and AVP, arginine vasopressin), the majority of which is released from the supraoptic nucleus in the hypothalamus
Do you have to reset your hypothalamus gland with medications?
No; normal, healthy individuals without a disease affecting their hypothalamus do not need to "reset" their hypothalamus with medications. Only in certain disease states do patients need to take medications to alter the function of the hypothalamus.
The hypothalamus has exquisite control over many regulatory functions of the body. These include hunger, day/night cycles, basal metabolic rate, growth, fertility, pregnancy, sexual behavior, temperature, etc. In most individuals, the hypothalamus does a marvelously good job at regulating these functions without any need for medication. In fact, trying to "reset" the hypothalamus with medications when it isn't necessary can actually lead to more harm than good.
What are the hormones released by the adrenal gland?
the medulla- adrenaline (epinephrine), noradrenadaline(norepinephrine), dopamine cotex- three layers, zona glomerulosa- aldosterone zona fasiculata- glucocorticoids like cortisol zona reticuaris- adrogens like testosterone
Adrenal hormones: Cortisol, norepinephrine and epinephrine.
What is the inner portion of the adrenal gland is the?
The adrenal medulla is the inner portion of the adrenal gland.
Is the ovary an endocrine gland?
It is both, actually.
A gland is an organ that secretes a substance. In the case of the ovary, it secretes estrogen and progesterone in response to FSH and LH from the pituitary.
As an organ, the ovary produces the hormones above (glandular function), but also houses and matures the ova responsible for reproduction.
