Hypophysectomy is the surgical removal of the hypophysis (pituitary gland). Indeed, the nostril also opens into the hypophysis. When this plan does not fully work, Kilgore abducts Deadpool and extracts his hypophysis. The hypophysis will later give rise to the radicle and the root cap. The third domain, the "basal embryo domain," contains the hypophysis. The last of the suspensors at the end of the embryo is known as hypophysis. Hypophysis later gives rise to the radicle and root cap.
