Adrenaline (epinephrine) and noradrenaline. They also produce androgens in their innermost cortical layer. The adrenal glands also affect kidney function through the secretion of aldosterone. Aldosterone affect the absorption of sodium.
The brain triggers the adrenals to produce hormones. This causes the gonads to produce testosterone in boys and estrogen in girls.

The pituitary gland starts puberty. This signals the testies and adrenals to produce more hormones.
Both the thyroid and adrenals produce hormones that affect heart rate.
Firstly, the brain triggers the pituitary triggers the adrenals to produce a lot of hormone. The testis and ovaries produce their hormones. This causes various physical changes to take place in the body.

The other way around. The pituitary is in charge. But there is feedback : adrenals to hypothalamus to pituitary to adrenals.
The scientific reason is that the brain directs the gonads and other adrenals to produce large amount of hormones. This causes various physical and emotional changes.
These are glands.
adrenals
Adrenals.
Adrenal glands produce hormones such as estrogen, progesterone, steroids, cortisol, and cortisone, and chemicals such as adrenalin (epinephrine), norepinephrine, and dopamine. When the glands produce more or less hormones than required by the body, disease conditions may occur.
