Question

Quizplus · Accepted Answer

The pituitary gland is composed of two lobes, the anterior lobe (or adenohypophysis) and the posterior lobe (or neurohypophysis). These two lobes arise from different embryological tissues (the anterior lobe develops from an outpocketing of the roof of the mouth, while the posterior lobe develops from neural tissue). The two lobes are connected to each other by a thin stalk of tissue called the infundibulum, but not by direct neural connections. The posterior lobe produces and secretes two hormones (oxytocin and vasopressin), while the anterior lobe produces and secretes several hormones. The anterior lobe is not the same thing as the neurohypophysis.
