Developing Pituitary - Human Embryo Carnegie stage 22

Human embryo Week 8, Carnegie stage 22
inset bottom right shows the complete head cross-section and approximate level of the plane.
- note the sphenoid "saddle" - only cartilage at this stage.
- trigeminal ganglia (CN V) and internal carotid arteries lateral to pituitary in complete head cross-section.
orientation - ventral is bottom of image, dorsal is top.
inset cross-section scale bar 1 mm.
measured regions are shown in microns.
neurohypophysis (posterior pituitary) containing hypothalamic recess.
adenohypophysis (anterior pituitary) containing developing blood vessels of local circulation.
