Pituitary

redbell

Of endocrine system
That shapes the basis ;
Regulates homeostasis .In streaming blood
The hormones flood,
Responding to stimuli
Of functions gone awry .

Take the hypophysis :

Undergrowth
Of the hypothalamus
On infundibulum,
A pendulous bell
Beneath the third ventricle—

Antidiuretic, oxytocin,
Growth hormone and prolactin :

How much one pees,
How tall one stands,
The birth of babies,
And the milk they demand .

Dominant this
Dichotomous gland
Weighing just grams .

Neonate
