Peptide hormones can easily diffuse into the cell membrane. Free hormones (without a carrier) are rapidly removed from the extracellular fluid.

Growth hormone is the hormone of darkness. While, Melatonin is activated por if the person is asleep.

Hormones can stimulate protein production, Hormones can stop protein production.

All adenohypophysis hormones stimulate a single organ tissue. Adenohypophysis also produces the hormone "Thyrotrophs","

Someof the T3 are converted to T4 in the kidneys. One important component for thyroid hormone production is the iodine.

Catecholamines stimulate the "Flight or Fight' response. Catecholamines also stimulates the feeling of pleasure."

One of the main function of Cortisol is to make more glucose by stimulating hunger. Another function of cortisol is for catabolism of proteins in all cells of the body.

Prolactin just like Oxytocin stimulates contraction of muscles during delivery, Oxytocin can also directly stimulate production of sex hormones.

Oxytocin is the main hormone for lactation. While the Prolactin is the main hormone for lactation.

Hormones can be activated at a certain time of the day. They can also be point activated anytime when the need arises.

The Vasopressin stimulates reabsorption of water from the kidneys specifically from the collecting ducts and the bladder to conserve body water. The Vasopressin is produced by the posterior pituitary gland.

The only thing that stands in the way for a drug to become a poison is "Dose". Antibiotics are administered in a timely manner.

The reason why antibiotic resistant organisms exist is due to the incorrect compliance and discontinued compliance of people to antibiotics. Antibiotics ca affect the nearby tissues surrounding the target organ

Methotrexate is a antineoplastic drug that inhibits kreb cycle. Ibuprofen is an anti-inflammatory drug.- First statement is correct

Drug distribution and drug removal from the body are both an important factor in TDM. Intake of two different drugs at the same time might cause a therapeutic failure.

. Intramuscular injections are the most common route for vaccines. It differs from subcutaneous injection by its angle, where IM uses a 45 degree angle and subcutaneous uses a 90 degree angle

The difference between the highest to lowest effective doses is called the pot Therapeutic range. And the lowest concentration of the drug obtained during dosing is referred as "trough".

Citrated plasma can be a specimen for TDM. Pills are easily absorbed by the GIT.

. Class Ill cardio active drugs are Calcium channel blockers. While, Class I are beta receptor blocker

Lipid hormones can easily get into the cytoplasm and bind to receptor proteins found in the cytosol. Sex hormones are lipid hormones and their precursor is cholesterol.

The 2nd dose of a drug is given during the peak of the first dose. The following doses after the second dose are each administered during the peak of the dose they follow

The main component of thyroid stimulating hormone is iodine. T3 is more biologically active than T4

Intravenous route of drugs does not require hepatic alterations of the drug. It gives a 100% bioavailability fraction.

. Drug metabolites can be excreted via the skin thru sweat. And, Can also be excreted via the lungs via lung fluid.

The Growth hormone-releasing hormone has many target tissues including point the bones for growth is synthesized and secreted by the hypothalamus.

Lipid hormones can easily get into the cytoplasm and bind to receptor proteins found in the cytosol. Sex hormones are lipid hormones and their precursor is cholesterol

Drugs can be difficult to measure since its concentration varies in the body. Its half-life and clearance also will vary."

For an accurate information regarding the timing, ask the patient directly on what time did he/she took the drug. Usually, if you want to measure a drug at its peak, you collect the specimen 1 hour after administration.

Binding of drug to a protein prolongs its half-life. A water soluble drug easily enters the cell membrane.

Ointments are administered by applying directly to the skin. Drugs absorbed by the skin are easily filtered by the kidneys.

There would be a lesser bioavailability for patients with malabsorption. While, the drug concentration in the body will be diminished in people with kidney disease.

The drug can be passed on to the infant via placenta passage of the drug. The drug is subject to renal filtration first before it will ever be altered in the liver."

The drug is broken down to its metabolites. The metabolites then goes to the target tissue or organ and exerts its effects."

Inflammation in the GIT can affect drug absorption. It can also increase the drug filtration.

Injections as route of administration gives the drug its full bioavailability. One of the factors for rapid drug action is its fat solubility.

Unbound drugs are spent rapidly. While all free drugs are bound to carrier proteins.

The total drug is composed of Free drug and the bound drug. While, drugs can be measured by measuring its metabolites.

Therapeutic drug monitoring is an area in laboratory medicine that ensures that a given drug dosage produce a minimal therapeutic effect and a maximal toxic adverse effects. It also ensures that the drug is life saving in serious situations.

Thyroid stimulating hormone is a hormone that stimulates TSH production. TSH is a single test for screening thyroid problems.

. Antidiuretic hormone are activated due to low extra-cellular fluid volume. It is also activated if there is a low RBC volume

Prolactin just like Oxytocin stimulates contraction of muscles during delivery. Oxytocin can also directly stimulate production of sex hormones.

The cortisol provides the liver amino acid from the breakdown of plasma proteins in all areas of the body. Cortisol also functions to slow down immune response and degree of inflammation.

1000ug of dexamethasone is administered. Blood collection for the dexamethasone suppression test is done at 9-10am.

Measuring the testosterone is one of the approaches to check male infertility. It can be accompanied by semenalysis procedure."

Aldosterone stimulates the kidney to reabsorb water. It has the same function with anti-diuretic hormone

Dopamine is not only produced in the adrenal medulla. Norepinephrine is from epinephrine.

Catecholamines stimulate the "Flight or Fight response. Catecholamines also stimulates the feeling of pleasure.

. The adrenal medulla is subdivided into three layers. Adrenal glands are a butterfly shaped glands above the kidneys.

The hypophysis is the largest portion of the pituitary gland. The posterior pituitary gland have specific specialized cells that produces specific hormones.

Both the Hormone of Darkness and Ascorbic acid are anti-oxidants. the precursor of Melatonin is somatostatin.

Hormones can be activated at a certain time of the day. They can also be activated anytime when the need arises.

The thyroglobulin houses the newly made thyroid hormones TRH directly releases TSH

Tyrosine is one of the precursor amino acids for Thyroid hormones and Catecholamines. Tyrosine combines with iodine for thyroid hormone formation

. Catecholamines are way more fast acting than mineralocort colds and glucocorticoids. Catecholamines would take minutes to take effect while mineralocorticoids and glucocorticoids would take days.

Aldosterone stimulates the kidney to reabsorb water, it has the same function with anti duretic hormone. - First statements correct

. Some of the conversion of T3 to T4 happens in the tissues outside the thyroid gland. Reverse 13 is a hormone with no significant biological use.

The main focus of the function of thyroid hormones is on metabolism Abnormal physical exam can be a reason to check thyroid hormone levels.

The main disorders of thyroid gland are autoiminune. Women above 35 years old are recommended to screen thyroid hormone levels

Most of the thyroxine is bound to a carrier protein. Proalbumin is one of the carriers of thyroid hormones

Free T4 means that the thyroxine is unbound. Thyroid hormones can be measure using radioimmunoassay.

Thyroid ultrasound is used to determine if there is a thyroid gland enlargement. It is also used to guide physicians on removing thyroid gland.

T3 and T4 are produced by the thyroid gland. Some 13 are indirectly produced by other tissues

FSH and LH are examples of Gonadotropin releasing hormones. Both FSH and LH are synthesized and released from the adenohypophysis.

Triodothyronine is the precursor of thyroxine. Thyroxine is the main Thyroid hormone

Monodeiodination is the process of removing one iodine from the T4. This process forms the T3"
