Endocrine System

usually an infection, swollen glands are your body's lymphatic system trying to fight off an infection.

Most often, the patient is given the radioactive substance in the form of a tasteless liquid or capsule. It may be injected into a vein (intravenously) in some instances.

When an individual touches a hot stove, the nervous system responds immediately by sending sensory signals from the skin to the spinal cord and brain, triggering a reflex action to withdraw the hand quickly. Simultaneously, the endocrine system may release adrenaline (epinephrine) from the adrenal glands, which prepares the body for a "fight or flight" response, increasing heart rate and enhancing alertness. This coordinated response helps protect the body from injury and prepares it to react to potential danger.

it is called an emergency hormone because during emergencies and when a person feels excited. It is secreted and therefore adrenaline rush happens, which refers to an activity of the adrenal gland in a fight-or-flight response, when it is releasing adrenaline (epinephrine).

Hyperthyroidism causes the metabolism to be unnaturally high. You can think of it like a car with the gas pedal pushed down to the floor. Just as a car will use extra gas when it is driven like that, your body will use extra calories trying to keep up with the needs of your thyroid hormone driven cells. Weight loss is very typical in hyperthyroid patients.

I know it sounds silly, but have you checked the furnace filter? Most problems start with a dirty filter. People dont change them often enough. You may also be experiencing a pluged capillary tube, dirty condencing coil, dirty evaporator coil, bad reed valves, ect.

Thyroid hormone increases the rate at which you use energy. It is one of the factors that affect metabolism.

They are called parathyroids and there are four. They are imbedded in the back quadrants of the thyroid gland. Parathyroids produce parathormone (PTH) which increases Calcium in the blood.

yes ofcourse you can get pregnant but u will have to take some medicines which will raise your progesrone level and iT WILL RAISE SOOOOOO FAST SO DONT WORRY SWEETY I WAS IN THE SAME BOAT AND NOW EVERYTHING IS OK AND WISH U LOTS OF BABY DUST.MAI

Eye drop forms of beta blockers, such as timolol (Timoptic), used to treat glaucoma.

Yes it is true that if you push your toung back you trigger the spit gland, but you have to puch it back a certain way.

you can get sick from not taking your thyroid medicine but you cant die from it.

it has things that are cool with extreme sports and bikes

Absolutely, get to your Dr. or get a better Dr.

The pituitary gland helps regulate the release gonadotropins. It also regulates melanocyte-stimulating hormones that produce the melanin for body pigmentation.

It is a mistake. The isthmus of the thyroid gland is a thin bridge across the trachea, linking the right and left lobes. It occasionally also gives rise to the pyramidal lobe, a normal variant of thyroid anatomy. The adjectival form of isthmus is isthmic, so a nodule in the thyroid isthmus is an isthmic nodule, not an isthmal nodule.

TSH stands for Thyroid Stimulating hormone it is secreted from the pituitary gland (which is an endocrine gland ) directly into the blood , circulates in the blood till it reaches the thyroid gland where it is picked by certain receptors and cause thyroid gland to secrete thyroid hormone which is of two types T3 and T4

ok, well its very simple, the gland called numeristine is what contains most of the iodine although some is contained in the well butox!

Gradients,streams and regulations

Electrical gradients--- b/w positive and negative charges, means they like to hold each other to make equilibrium.

eg. ICF with K ions, ICF try to keep K ions inside the cells, As cell is negatively charged and K ions are positively charged.

Concentration gradients--- b/w higher and lower concentration, means they try to maintain same concentration b/w each other.

eg. Osmosis and diffusion,

in osmosis fluid (solvent) moves from higher concentration to lower concentration of solvent through semipermeable membrane.or solvent moves to high solute concentration.

In diffusion solute particles moves from high solute concentration to low solute concentration.

Pressure gradients--- b/w higher and lower pressure, means they try to maintain same pressure b/w each other.

Eg. Beginning of the expiration alveolar pressure is 1mmHg and atm pressure is 0, so in expiration air moves from high pressure to low pressure, ultimately out of body and expiration takes place.

Or inflated balloon has much higher pressure than room pressure, by laplace law less the radius more the pressure, means pressure is inverse to radius so when you leak the balloon air moves from balloon ( higher pressure) to room(low pressure.)

Down gradient---- same as down stream, no need of energy. Natural ways in which all gradients work.

Up gradient--- opposite to down gradient and same as up-stream, needs energy. Against the gradients or natural processes.

Down stream---- simply it means in the direction of flow, or in a natural way as all gradients works. it does not need energy. In other words we can say it's a passive transport.

With an example suppose you swim in a river in the direction of water flow. You do not have to consume your energy because you are in down stream.

Up stream---- simple it directly inverse to down stream, you need energy. In medical view we need ATP to proceed it. Eg. Na/K pump.

Or swim in opposite direction of water flow you can imagine how much energy you will have to spend on it.

Down regulation--- this concept may disrupts you until you are familiar with feedback mechanisms. Down regulation-regulation of anything in order to down. When concentration of any molecules has increased than normal in the ECF then it sends signal to hypothalamus to bring it back to normal or decrease it. It's also a maintaining mechanism in our body.

Eg. When in the blood there is increased level of T3 and T4 , through the signal pathways TSH is decreased in order to drop the level of T3 and T4 or to diminish the production of these. Finally body is trying to maintain equilibrium.

It is more used in pharmacology and biochem.

In other words is same as negative feedback mechanism in endocrine system.

eg. When in the blood there is increased level of T3 and T4 , through the signal pathways TSH is decreased in order to drop the level of T3 and T4 or to diminish the production of these. Finally body is trying to maintain equilibrium.

Up regulation---- just opposite to down regulation. Same as positive feed back mechanism. When something has decresed it will be increased through up-regulation process.

Same example of T3,T4 &TSH can be used to understand it in opposite phenomena.

No, it's GABA transaminase antagonist.

The thyroid is a butterfly shaped gland in the front of your neck. The thyroid gland secretes hormones the body needs to function. Thyroid disorders are not contagious diseases. Hypothyroidism means not enough of the hormones are made and released. Hyperthyroidism means the gland secretes too much of the hormones. Thyroid problems are not something you "catch" from someone else.

No. Why the heck would you want to, anyway? Last time I checked, babies aren't born from the NASAL canal!

The antidote is Terbutaline.

Calcium gluconate is the antidote for magnesium sulfate.

The hypothalamus is a collection of specialized cells that is located in the lower central part of the brain, is the primary link between the endocrine and nervous systems. Nerve cells in the hypothalamus control the pituitary gland by producing chemicals that either stimulate or suppress hormone secretions from the pituitary.

Although it is no bigger than a pea, the pituitary gland, located at the base of the brain just beneath the hypothalamus, is considered the most important part of the endocrine system. It's often called the "master gland" because it makes hormones that control several other endocrine glands. The production and secretion of pituitary hormones can be influenced by factors such as emotions and seasonal changes. To accomplish this, the hypothalamus relays information sensed by the brain (such as environmental temperature, light exposure patterns, and feelings) to the pituitary.
