Wonder fills the air as I hear the word Pituitary..

Then it whispered to me, "Selina, please google me.."

But then I started to shiver, I was frightened..

Sweaty palms and senses heightened..

"Oh God, please help me!" words I uttered on bended knees..

Confusion sinks in, fright started to ease..

Is this dementia or some kind of disease?

Did it just speak to me or was it just the breeze?

I sat down confused and turned to my PC..

Clicked on a page and I was like "OH EM GEE!"

The pituitary is no larger than a pea!

I scrolled down and it explained further to me..

Two parts it is comprised of, posterior and anterior

Awestruck and inquisitive, I said “what are they for?”

Vasopressin and Oxytocin secreted by posterior..

Anterior lobe I will elucidate furthermore..

Adenohypophysis, a name it is better known,

Marveling eyes dilated, dexterity honed,

Information overload as I sighed and moaned..

Now I will tell you about its hormones..

Growth hormone (GH) also known as somatotropin,

Peaks greatest at puberty, with age, slowly declining..

Its deficiency will cause dwarfism..

Excessive production leads to acgromegaly or gigantism..

Thyrotrophs secrete Thyroid-stimulating hormone (TSH)..

Thyrotropin-releasing hormone (TRH) is what causes its stimulation..

Inhibition is caused by the arrival of somatostatin..

Also known as thyrotropin, did you know it's a glycoprotein?

Do I have to further enlighten you about what it does?

I reckon it is a little bit too obvious..

But for you, if its function is unbeknownst,

It stimulates the thyroid gland to produce its hormones..

Prolactin is secreted by lactotrophs of the pituitary..

Its levels kept low by dopamine, which is inhibitory..

Responsible for initiation and maintenance of lactation..

Its secretion, as I read on, is in a circadian fashion..

Pituitary necrosis or infarction is seen with its deficiency..

For women, so is menstrual disorders and infertility..

Hyperprolactinemia leads to inhibition of GnRH secretion..

Which also results to infertility and sexual dysfunction..

My head is throbbing, I can feel the stabbing pain..

My heart is pounding, juices leaking out of my brain..

I think I am losing my grip on reality again..

As I took a sigh of relief, I closed my eyes and counted to ten..

Secreted by gonadotrophs is the Leutenizing hormone (LH)..

Stimulation of Leydig cells in the testes to produce testosterone..

In the middle of the menstrual cycle, prompts the ovulation..

Are you sick of the rhyming? It then produces progesterone..

Follicle-stimulating hormone (FSH) is next on the list..

Are you aware that without this you and I would not exist?

In females, it acts upon the follicle to release estrogen..

I may be hyperventilating, I think I need some oxygen..

In males, it stimulates the production of the sperm..

Yes, the little things that swim around and squirm..

Deficiency of FSH may halt spermatogenesis..

And in females, failure of ovulation by the ovaries..

The corticotrophs secrete Pro-opiomelanocortin (POMC)..

Which then forms the last hormone, Adrenocorticotropin(ACTH)..

Acts upon the cells of the Adrenal cortex and stimulates it..

Am I boring you? I promise you this is the last bit..

Cushing's disease, result of overproduction of Adenocorticotropin..

Insufficient amount leads to hypopituitarism..

I am sure you enjoyed the rhyming trend..

But I am certain you are ecstatic that this is the END.. :)

HAPPY READING ! Hope you enjoyed the poem.. :) ( I swear I worked hard on it..:P )

I was very hesitant about making a blog so I waited until the last minute to do it.. I have no idea what to write but there's just one thing that's been bothering me.. I had trouble sleeping.. I couldn't eat.. I was so frustrated! Can you guess what it is? Yeah! I'm really worried about which template to use! There's just so many of them! Different designs. So many colors! I cannot pick just one! HAHA.. :) Kidding aside, I'm worried about how I'm going to start this blog.


For the average people, when they hear the ENDOCRINE SYSTEM and ENDOCRINOLOGY, they immediately associate it with hormones, growth, metabolism, glands, and development. But let’s run away from mediocrity and think deeper and more creatively..

Have you ever wondered, what turns you on? What makes your breasts grow? Have you asked the question why is she taller than me? Why does this girl have a mustache? Why is she so moody? And what causes a guy’s erection?

YES, endocrinology answers all of these questions...

Endocrinology is not just a boring branch of biology and medicine dealing with the endocrine system. It doesn't just tackle specific gland secretions called hormones which initiate biochemical reactions responsible for homeostasis. It doesn't just talk about the enzymes that hastens or catalyzes reactions. It also answers questions of how and why. It gives us the reasons for physiological changes in our body.

It is wonderful to study Endocrinology because it gives us a cause and effect relationship about things that are happening in our body. So, it’s not true that men grow taller because of circumcision. Neither does masturbation for those who are wondering. ;)

Now who's ready to hear about the fun stuff???

We have these so called endocrine glands.. And these are the amazing little buggers responsible for the production and secretion of our hormones.. Maybe I can compare them to the gears of a well-oiled machine.. :) Gears are interdependent on one another.. They would not work without the other.. And the machine would not function as well as it should be if its parts are not working properly..

Now let me introduce you to the endocrine glands.. :)) (drum roll please!)

  • Hypothalamus
  • Pituitary Gland
  • Thyroid Gland
  • Parathyroid Glands
  • Adrenal Gland
  • Pineal Gland
  • Pancreas
  • Reproductive Glands or Gonads
Are you bored yet? If you are, I think it's time to watch a little video.. :)

Isn't learning fun? :)) And I'm pretty sure that the video made you smile.. endoCRIIIINNNNEEE :) Credits to Rajshrikids for the video..

If you wanna learn more about the endocrine glands (and I'm sure you do because you like wasting your time reading my stupendous blog), I've explained them further here.. :)) enjoy!


Being a full-fledged party animal, Britney Spears' song "Toxic" is what comes to my mind when I hear the word.. "With a taste of your lips I'm on a ride.. You're toxic, I'm slipping under.. With a taste of your poison paradise.. I'm addicted to you don't you know that you're toxic?" I'm sure you were singing along with me and shaking what your mama gave you as you were reading the lyrics to the song.. HAHA.. :))

But eventually, my scientific instinct kicks in.. Oh! Yeah! It's the study of the adverse effects of chemicals on living organisms..

When is enough, enough? (I know it's redundant but I'm trying to make a point here so bear with me..) How much is too much? How plenty is a spoonful? How huge is a huge amount? And how minute is minute? LOL.. Wasn't that fun? :)

Anywhoooooo, To simplify the definition, Toxicology is a branch of science which studies our physical limit, resistance and tolerance to different chemicals and substances.. :)
"All substances are poisons - the difference is in the dose"


Drug Testing

Now who could forget this scene? My heart literally stopped beating when my dear Edward Cullen said these lines.. "Your scent is like a drug to me, you're like my own personal brand of heroin." (Twilight fans screaming in the background) WOAH! I've watched it like 5 times before I posted it here and it gave me goosebumps every time I hit play.. :) My arrector pili muscles would not behave! :) (yes, I listened during Anatomy class)

Is it too obvious that I'm way too excited for Breaking dawn to come out? hahaha! Sorry if I sidetracked you readers (if there are any :/ )

Drug testing is usually done to check for illegal drug abuse by employees (before an offer of employment or random drug testing after hire) and also for students (before admission to a university).. A drug test can also be utilized to assess possible accidental or intentional overdose, monitoring compliance with a rehabilitation program and to determine presence or absence of drugs involving medico-legal purposes.. Oh BTW, medico-legal purposes, for those whose noses are oozing with blood, has something to do with forensics.. YUP, the cool stuff we watch on CSI, NCIS, Criminal Minds, Bones, etc.. :)))

Urine specimens, venous blood, saliva and even strands of hair can be used for drug testing.. Isn't that just astounding? Admit it.. The advances in technology nowadays are so marvelous that even small samples taken from your fingernails may be used to conduct a drug test..

If the test is used as a way of screening, illegal drugs, prescription drugs and alcohol can also be detected.. Here's a list of commonly abused and commonly tested substances:

  • Cocaine
  • Amphetamines
  • Heroin
  • Morphine
  • Phencyclidine (PCP) (aka angel dust)
  • Alcohol
  • Benzodiazepines
  • Hydromorphone
  • Tetrahydrocannabinol (THC) (the active ingredient in Marijuana)
  • Propoxyphene
  • Methadone
  • Codeine
  • Barbiturates
  • Antidepressants
Guys that's all for now.. Keep reading my blog.. And please vote for me :))
