Study the given figure showing various human endocrine glands. Select the correct statement(s) regarding these.
(i) Gland P is stimulated to secrete its hormones by thyrotropin secreted by anterior lobe of pituitary gland.
(ii) Gland R is associated with the secretion of hormones corticosteroids, epinephrine and norepinephrine.
(iii) Glands T and U represent the sex glands, which are derived from the mesoderm of embryo.
(iv) Gland Q is derived from mesoderm of the embryo and its increased size results in ageing.
(v) Gland S secretes the hormone glucagon which stimulates the liver to convert glucose into glycogen.
