Identify the differences between the posterior pituitary and the anterior pituitary. (Select all that apply.) -The posterior pituitary's release of hormones is controlled by releasing hormones, whereas the anterior pituitary's release of hormones is controlled by negative feedback. -The posterior pituitary does not produce the hormones it releases, whereas the anterior pituitary produces the hormones that it releases. -The posterior pituitary releases steroid hormones, whereas the anterior pituitary releases amine hormones. -The posterior pituitary releases oxytocin and vasopressin, whereas the anterior pituitary releases tropic hormones.
