Other Hormone Communication Exchanges

The Thyroid Glands

The hormonal system’s other distribution centers include the thyroid. The thyroid gland regulates your body’s metabolism, so you can enjoy a healthy life. Thanks to thyroxin, a special hormone it produces that affects all the cells in the body, determines the amount of oxygen those cells will use.

For example, if thyroxin is given to a cell in which mitochondria are present, then its oxygen consumption and energy production rise. Insufficient thyroxin in the blood leads to a slowing of the metabolism and increased levels of water and sodium in the tissues. 55

The thyroid’s production and secretion of thyroxin again take place thanks to an interconnected system. Thyroxin’s secretion is brought about by another hormone, thyrotropin, secreted from the anterior lobe of the pituitary.

Calcitonin is yet another hormone secreted by the thyroid gland. Together with the parathormone (or PTH) secreted by the parathyroid gland, calcitonin plays an important role in regulating the body’s calcium-phosphate level. Regulation of calcium levels is of vital importance, since this substance is used in such essential processes as bone formation, the functioning of the muscular and nervous systems, blood clotting, and active carriage from the cell membrane. Therefore, a specific level of calcium needs to be maintained in the bloodstream. That explains why the bones act as a kind of bank, storing calcium. These two different hormones allow calcium to be “deposited” in or “withdrawn” from the bones. 56

The parathormone produced by the parathyroid gland, located above the thyroid, plays a role in helping calcium stored in the bones get returned to the blood. This hormone’s secretion is regulated without any direct influence from the pituitary or nervous system, but automatically, depending on the level of calcium in the bloodstream. This hormone identifies when the level of calcium in the blood has fallen and accelerates the passage of calcium from the bones. Then when the level of calcium in the blood exceeds a certain level, the thyroid secretes the hormone calcitonin, which causes excess calcium in the blood to pass into the bones for storage there. 57

If there is a lack—or excess—of this hormone of such great importance, what sort of problems arise?

In the case of too little parathormone, the level of calcium in the blood decreases, accompanied by contractions in the muscles, especially those of the hands and face. If this constriction occurs in the muscles of the windpipe, breathing is obstructed, which may lead to death. Too much of the hormone causes excessive calcium being released into the bloodstream from the bones, which become easily bent or broken. The kidneys try to expel the excess calcium from the blood, but these crystals of calcium can lead to kidney stones. 58

As these examples show, we humans can live healthily and comfortably, thanks to our hormonal system functioning fully. Indeed, just a small deficiency in the thyroid gland alone can lead to a great many diseases. So who has established and maintained such a perfect system? Who realizes which substances have decreased in the bloodstream, identifies the level of the deficiency and produces the necessary substances, knows what these substances must contain and keeps producing them for a long as required, to effect all the other organs in the body? Does the thyroid itself exhibit such a will? Such a possibility is quite impossible, of course. The thyroid gland is only a community of cells, in which it is impossible to seek anything possessed of consciousness.

Neither can we say that this will or intention belongs to the hormones. What we call a hormone is a collection of molecules. That being so, where must we look for that will?

The sole conclusion we encounter at this point is the fact of creation. All the glands in the body, all the elements comprising the hormonal system, the hormones they produce, the molecules within those hormones and the atoms constituting those molecules are all products of Allah’s incomparable creation.

The Importance of the Adrenal Glands

Adrenalin, one of the important hormones produced in the adrenals, serves a very interesting purpose, causing various sudden bodily changes in times of emergencies. These changes represent a kind of preparation in the face of abrupt danger. As an example, imagine someone exposed to imminent threat—who is attacked by an animal, for instance. In the seconds that follow, that individual’s body will have requirements very different from those prevailing under normal conditions. His muscles will need to move faster, his blood pressure to rise and the heart to beat faster. He will thus be able to run faster, flee quicker, or deal with the danger in a more powerful manner. But how is all this to happen?

When danger approaches, the body’s alarms are activated. The brain sends a fast command to the adrenal gland, whose cells go into action and swiftly release molecules of the hormone adrenalin. The adrenalin is released into the blood and distributed to the various regions of the body.

The adrenal gland and the sections in it are shown.
A) The outer part of the gland is the cortex, and the inner part the medulla.
The stimulation of and hormones secreted by these regions are different.
B) The regulation of the hormone secretion of the cortex part
of the gland takes place as follows:
the hypothalamus and the pituitary arrange for hormones
to reach the shell region of the adrenal gland with the blood,
and for the hormone cortisol to be secreted there.
This plays various important roles, such as increasing blood sugar levels
and arranging the storage of glycogen in the liver. Clearly,
the way the kidneys act to regulate the body’s activities with
a command from the brain cannot be carried out by the cells.
This is of course Allah’s incomparable creation. 
Signals from the cerebral center

The hormone adrenalin has one purpose: to place the entire body on action stations and allow the individual to become stronger, more resistant and faster.

The secreted adrenalin molecules adjust the veins, allowing more blood to reach vital organs in this case of emergency. Cells around the blood vessels leading to the heart, brain and muscles obey and cause the arteries to expand, so that more blood reaches those vital organs.

The adrenalin molecules also cause arteries going to those organs that will not be needed to contract, thus ensuring that less blood reaches them.

The effect of the adrenalin widens arteries leading to the heart, brain and muscles and also contracts those leading to the skin and the liver. Extra support is thus provided for the organs the body needs most. The vessels leading to the heart or brain never contract by mistake, nor do those going to the liver or skin contract in error. The adrenalin molecules know very well what they must do. The blood vessel cells obey them to the letter. The diameters of hundreds of vessels in your body, and how much blood they will deliver and where, are regulated by the mind of a hormone too small to be seen with the naked eye.

There is another reason behind less blood being pumped to the skin. In the event of injury, the risk of blood loss is minimized. The pallor of the face at times of extreme excitement is also due to less blood being pumped to the skin at that time.

Adrenalin molecules mean something different to every organ:

The adrenalin molecules that widen the blood vessels also accelerate the contractions of the heart muscles. The heart thus beats faster and provides the muscles with the blood they need for extra strength.

When the adrenalin molecule reaches the muscle cells, it permits them to contract more powerfully.

The adrenalin molecules instruct the liver cells to release more sugar into the bloodstream. The level of blood sugar rises, and the muscles are given the extra fuel they need.

As a result of all these special adjustments, a 100% increase in strength takes place. Thanks to the changes that adrenalin causes in the body, a person becomes able to think and make decisions more quickly, is able to fight more strongly and run faster, and also becomes more resistant.

Adrenalin molecules know very well what kind of bodily changes the body needs in times of danger. Moreover, the molecules prepare the body against danger in a most harmonious manner.

Every tissue and organ that the adrenalin reaches begins acting toward a common purpose. No organ acts outside of—or in conflict with—that common goal.

The reactions the body needs to make and the precautions that need to be taken in emergency situations have all been prepared, outside the person’s knowledge or control. The adrenalin hormone’s effects on the body once again prove that its workings have been created in a special manner to be compatible with one another.

HORMONES THAT REFUTE DARWINISM

Although you have never been aware of them, thousands of commands pass inside your body at every moment, making your life as convenient and easy as possible. 

For example, when you are excited or afraid, your nerve cells immediately stimulate the adrenalin glands at great speed; the signal reaches them without getting lost on the way. Receiving the message, the glands secrete the hormone adrenalin. This hormone is released into the bloodstream and effectively sets the whole body in a state of alarm. It stalls the actions of the digestive system and halts the digestive process, thus freeing an important quantity of blood to nourish the muscles. At the same time, the rhythm of the heart is accelerated. Blood pressure rises, and the sugar level in the blood goes up, providing extra energy for the muscles. The pupils expand, increasing the eyes’ sensitivity to light. When all of these effects are combined, a person becomes ready to perform better, whether that he chooses to flee, defend himself, or attack.

The nerve cells are structures consisting of inanimate, unconscious atoms. Yet they immediately understand the conditions required by the body and instantly send messages to the relevant body parts. The sites receiving that message also came into existence by the assembly of inanimate atoms. Nonetheless, they immediately understand the message and go into action to produce the requisite hormone, which travels through the whole body and places the relevant organs on alert. To imagine that such a conscious, planned, organized and target-directed system came about by chance is to turn one’s back on logic and common sense. By maintaining that all these systems and organs did in fact come into being accidentally, Darwinists place themselves in a laughable situation. 

Despite being an evolutionist and an atheist, Malcolm Muggeridge made the following admission concerning Darwinism’s position: 

I myself am convinced that the theory of evolution, especially the extent to which it’s been applied, will be one of the great jokes of the history books in the future. Posterity will marvel that such flimsy and dubious an hypothesis could be accepted with the incredible credulity that it has.(Malcolm Muggeridge, The End of Christendom, Grand Rapids: Eerdmans, 1980, p. 43.)

Glands That Create the Differences Between Men and Women

When a person reaches puberty, the pituitary realizes that certain changes need to be made in the body and sends a series of commands to the sex glands, or gonads. At this, a hormone secreted in the female sex glands (estrogen) matures the female body and regulates the development of the reproductive organs and bodily structure, while another hormone, progesterone, prepares her for pregnancy.

Testosterone, another hormone secreted in the male sex glands allows the male physical form to mature and regulates sexual development.

The hormones produced by the pituitary and thyroid glands in both male and female bodies possess pretty much the same characteristics. Once puberty has been attained, however, the gonads produce completely different hormones. When the body matures, the sex hormones that are never secreted during childhood go into operation in a particular order and at the appropriate time. How does this phenomenon take place?

A molecule in your body calculates the time that has passed, and goes into operation at a specified time. It is astonishing that an inert substance should calculate the passage of time and, furthermore, that it should go into operation at roughly the same age in all human beings. How does a hormone know about the passage of time? Such a thing is, of course, impossible. It is Allah, the hormones’ Creator, Who sets hormones into action at specific times. It is Allah Who stipulates when they will be secreted and when that process will stop. Allah is He who knows all forms of creation.
