Anterior Pituitary Hormone

Endocrine System consists a variety of glands
Ductless is what they are, for they have no tubules to pass
Secreting hormones is its main function
To regulate the body in progress to prevent any obstruction

Master gland is what they call it
May also be hypophysis if you want to sound like a geek
The pituitary is the gland that I am referring       
In this poem, anterior part of it is what you would be learning

Anterior pituitary, also known as adenohypophysis
Where stress, growth and reproduction are its major gist
It’s bigger than the posterior if I would like to discern
Regulates physiological processes are its primary concern

Hypothalamus has the power over the anterior
Acts like a chief in sending stimulus to the supervisor
Wherein, release of hormones is definitely rapid
To the target organs that needs it exactly

Have you ever thought why others are small?
Seems like a kid but the features are old
It’s because of GSH that should promote growth
Has a failure known as hyposecretion

3, T4 and Calcitonin are discharged by the Thyroid Gland
This is not a part of the Anterior Pituitary but I would like to add
For they are correlated to one another in this special function
The negative feedback is the process that I would love to mention

When Hypothalamus secretes TRH, the pituitary will be whipped
TSH will now be freed and send signal to thyroid in just a one click
From the time this happens, TH won’t hesitate to be secreted
To avoid hormonal imbalance, negative feedback must be completed

Once there is sufficient TH, Thyroid gland will now act
Let Hypothalamus know that enough has been construct
So, no TRH and TSH will be able to stimulate the secretion of TH
And the whole body is now in cloud nine and harmony

Bulging eyes, excessive sweating and weight loss
Hyperthyroidism is the most common cause
You may have developed Grave’s disease as you may know
Or for layman’s term, TSH secretion went too low

ACTH is another hormone that will be produced
Stimulation of adrenal cortex  is the primary purpose
To secrete glucocorticoids, mineralocorticoids and androgen for males
While, estrogen is also made to help the mom in giving birth

When the mom is still in the stage of pregnancy
Prolactin is produce and acts already
Preparing the breast for future milk production
To nourish the baby when introduced to the new world

LSH and FSH are the perfect duo
Acting on gonads of our dear sisters and bro
Stimulates production of progesterone, estrogen and testosterone
For a baby to come and be born

All of these are nice to know
To educate us of how our body works
All praises to God is all I want to give
To what He have done to you and me
