Slide 1: Pituitary, saggital section, cat, H&E. Shows structural relationships of the anterior and posterior pituitary with the stalk and hypothalmus. The space in the anterior lobe between the pars distalis and pars intermedia represents a remnant of Rathke's pouch which would not be seen in a human pituitary. The space in the pars nervosa and infundibular stalk would also not appear in a human pituitary. Note the cellular nature of pars distalis, the fibrous appearance of pars nervosa, and the small follicles in the pars tuberalis (around top of infundibular stalk) and in the pars intermedia.
