===Pituitary Gland===
<FlashCard questions="10">
|q1=Describe the location of the Pituitary Gland.
|a1=The pituitary gland, or hypophysis lies within a bony cavity, the Sella Turcica, in the base of the skull just ventral to the hypothalamus. It lies between the more rostral Optic Chiasma, and the more caudal Mammillary Bodies.

|a2=
*A. Pars Tuberalis
*B. Pars Distalis
*C. Pars Intermedia
*D. Pars Nervosa
