Does the anterior and posterior pituitary actually synthesize any hormones? Or do they simply release what's made from the hypothalamus? That is to say: are all hormones released by the anterior or posterior pituitary gland actually made in the hypothalamus?

Posterior pituitary doesn't synthesize its own hormones.

Anterior pituitary does. FSH, LH, ACTH, TSH, growth hormone, and prolactin are made there

you need to know this for the MCAT now?

always needed to know the common hormones..

FLAT PhG = synthesized in anterior pituitary when stimulated by the hypothalamus

Oxytocin and ADH (Vasopressin) are synthesized in the hypothalamus but released from the posterior pituitary

Okay, thanks. So just the posteriors are synthesized in the hypothalamus. Thanks!

This maybe a little extra information past necessary MCAT knowledge but, the alternative names for anterior and posterior pituitary help me remember this stuff.

Anterior - ADENOhypophysis: Adeno means gland, implying that this portion synthesizes and secretes its own hormones.

Posterior - NEUROhypophysis: Neuro refers to the synthesis of the hormones from a neural component (hypothalamus) and nerve controlled release from the posterior pituitary.

Hypophysis gland is another name for the entire pituitary.
