The anterior pituitary contains the '''pars distalis''', and the '''pars tuberalis'''. This part of the pituitary gland is controlled by ''releasing factors'' from the [[Hypothalamus - Anatomy & Physiology|hypothalamus]]. These factors reach the anterior pituitary via the '''hypophyseal portal system''', venous channels allowing direct passage between the hypothalamus and the pituitary gland. The anterior pituitary gland secretes two types of hormone:

The '''pars distalis''' contains five cell types which produce six hormones. '''Somatotropes''' and '''lactotropes''' are ''acidophillic''. '''Corticotropes, thyrotropes''' and '''gonadotropes''' are ''basophillic''.
