Final answer:
The pituitary gland is responsible for producing hormones that regulate growth and directly activate the adrenal glands.
Step-by-step explanation:
The gland(s) producing hormones that regulate growth and also directly activate the adrenal glands is the pituitary gland. The pituitary gland, often referred to as the 'master gland' of the endocrine system, is responsible for controlling and influencing other endocrine glands. One of the hormones secreted by the pituitary is the adrenocorticotropic hormone (ACTH), which directly stimulates the adrenal glands. The anterior lobe of the pituitary gland produces various tropic hormones, such as the thyrotropic hormone that stimulates the thyroid gland. Additionally, the pituitary gland produces growth hormone, which influences growth and development throughout the body.
