It consists of two lobes of differing embryonic origin, the anterior lobe (adenohypophysis), which secretes most of the hormones, and the posterior lobe (neurohypophysis), which stores and releases neurohormones that it receives from the hypothalamus. Called also glandula pituitaria [TA alternative] and pituitary body. hypophysial adj

Hypophysis, subdivided into its two lobes, the adenohypophysis and neurohypophysis.
