It is sometimes called adenohypophysis because it is more of a gland than anything else: the posterior pituitary. This gland arises from an outgrowth of ectoderm at the base of the hypothalamus. It is sometimes called the neurohypophysis because is arises from neurological tissue. There is no relationship between the posterior and anterior pituitary. The hyophyseal fossa has two parts, the tuberculum sellae in the front and the dorsal sellae, that create the turke"s saddle. The inferior hypophyseal artery travels to the posterior of the pituitary before exiting through the posterior hypophyseal veins. Explain the pituitary at embryonic development: between 5 to 16 weeks, two pouches will begin to from: at the top, a neurohypophyseal bud will form, and at the bottom,
