	(A) Hypothalamus
	(B) Anterior pituitary
	(C) Posterior pituitary
	(D) Pineal gland

(3) Gonadotropin releasing hormone (GnRH), released from the hypothalamus, induces the synthesis and release of the following hormones by the anterior pituitary gland:

	(B) Luteinizing hormone (LH)
	(C) Prolactin
	(D) Growth hormone (GH)
	(E) Thyroid stimulating hormone (TSH)

(4) This pattern of gonadotropin releasing hormone (GnRH) release from the hypothalamus is essential to properly trigger the start of puberty in males and females, as well as to establish regular menstrual cycles in females.

	(A) Constant rate of release
	(B) Pulsatile pattern of release

(5) During human puberty, the end of linear growth in long bones is caused by the closure of the epiphyseal plates of the long bones. This is due mainly to the action of this hormone (in both sexes):
