Pituitary gland is one of God miracles, it weighs approximately 0.5kg (small chic-pea has the same weight). Although pituitary gland is a small gland, it secretes several main hormones into blood stream  and it  carries instruction to other endocrine glands in order to stimulate them to release their hormones into blood stream.

In a state of anger, pituitary secretes a hormone that stimulates Adrenal gland to release Adrenalin hormone into blood and that hormone  produces about amazing chemical , biological and physiological changes; it prepares the body a if it were about to face   satanic powers as a response to threat sign resulting from  (anger) state. Adrenal gland secretes also cortical hormones such as Cortisol to prepare the body biologically to defend its self against psychological exhaustion.

If a person undergoes  these feelings for  a long time , hormones secretion will increase resulting in damaging chemical changes; these are :body tissues damaging, secreting  Glucose into urine…. And in the course of time , it might cause (Diabetes) , moreover  Cholesterol increases gradually in blood with the result of a potential  Angina Pectoris, Atherosclerosis (Hardening of the inner lining (intima) of arteries. ) in addition to many other serious serious diseases such as    (psychosomatic) diseases.

Containing anger , forgiveness and avoiding tension is the correct ways to release the damaging psychosomatic powers which damage you.   It is the shining way towards the sentimental stability , the psychological security and the spiritual happiness

Pituitary Gland  Position

Pituitary gland localizes in the frontal base part of the brain and is connected to the Hypothalamus- a region between the palate  and the brain

base, which is secure place . It is an important gland; it secretes many essential hormones, it is the master  of several other endocrine glands, because its  hormones are the essential regulators and the main effectors of endocrine glands.

Microscopic Structure of Pituitary Gland

It consists of tow lobes that structurally and functionally differ from each other

1. Anterior Lobe (Adenohypophysis) which consists of epithelial cells.

2. Posterior Lobe (Neurohypophysis) which consists of para-neurons.

Hormones secreted from the anterior lobe can be classified into two groups:

a. Hormones that  affect body tissues directly.

b. Hormones that affect other endocrine glands and stimulate them to release their hormones.

Common Pituitary Gland Hormones

Growth Hormone (GH): This is responsible for tissues and organs growth. Its main function is to stimulate cells to the produce protein required for tissues formation.

Anterior Pituitary

This part consists of terminal anterior lobe and mid lobe. The anterior lobe produces at least six protein hormones in spite of its small magnitude (volume).

1. Thyroid Stimulating Hormone (TSH) regulates thyroid gland hormonal secretion.

2. Adrenocorticotropic Hormone (ACTH) stimulates adrenal cortex.

3. Two of stimulating hormones are called Gonadotrropic Hormones because they affect gonads: the first one is Follicle Stimulating Hormone (FSH).

4. The second one is Luteinizing Hormone (LH) which stimulates connective  cells.

5. Prolactin (PRL) stimulates milk production from mammary glands in females. It also has other roles in primitive vertebrates.

6. Growth Hormone (GH) is responsible for structural formation such as bone elongation, proteins precipitation in muscles and body formation.

In primitive vertebrates, mid lobe releases Melatonin that Stimulates a hormone (MSH) that controls black stain (pigment) diffusion inside the cells containing pigments in order to enable those cells to match animal habitation more  successfully.

In mammals and birds, posterior lobe produces Melatonin stimulating Hormone (MSH) rather than mid lobe which doesn’t exist in birds and some of mammals. It seems that (MSH) has a minor role in dying in case of endothermic animals although it causes skin darkening when it is inoculated into blood stream.

Pituitary is controlled by the hypothalamus; a portion of brain that  attaches nervous control systems to endocrine glands.

Pituitary gland has mainly a regulatory function as it secretes the harmones of gigantism and dwarfism , the hormones that stimulate the reproductive glands , Oxytocin (OT).( A hormone useful in promoting   delivery.) and urine diuresis –suppressing Hormone 

Posterior Pituitary

Posterior lobe of pituitary isn’t true endocrine gland, it is the centre of storing and releasing the hormones produced in the hypothalamus ,which produces two hormones that are chemically similar. These are :

a. Oxytocin (OT).( A hormone useful in promoting contractions of the uterus at the time of delivery; also stimulates milk production during lactation.)

b. Vasopressin. (An agent which causes constriction of blood vessels  .)

Both of hormones are polypeptides contain eight amino acids that are  called (Octa Peptides) and they are fastest hormones whereas they can bring about response within  seconds of their release.

Oxytocin has two reproductive functions in mature females of mammals. It stimulates smooth muscles of uterus to contract during delivery . This hormone (ISF) is used to help woman undergoing  difficulties during delivery and to stop bleeding after delivery. It also releases milk from mammary glands in response to nursing (suckling). This hormone also exists in males but its function is unknown.

Vasopressin affects kidney to restrict urine excretion (conserves water in the kidney), hence it is called Antidiuritic Hormone (ADH). There is a minor function of this hormone; it contracts smooth muscles of arteries so that it raises blood pressure.

Dear Muslim brother,

have you seen the amazing ingenuity in a half gram-weighed gland??

Where the so-called scientists to ponder over God miracles that cripple human brain??

  After preceding review, we should bow to God, the Absolute Creator. God is the creator , who figures and invents.

  {These are God creatures, who else could create thing}
