Answer:
The correct answer is the third option - endocrine signaling.
Explanation:
The endocrine signaling takes place when endocrine cell organs or glands release hormones that flow through the bloodstream and that act on distantly located target cells in the body. The endocrine system includes several glands that release or secretes different hormones.
The pituitary gland transfers signals to other endocrine glands to release or inhibit their hormone production according to the brain signals. The adrenocorticotropic hormone (ACTH) is released by the anterior pituitary gland that stimulates cortisol release in the adrenal glands in stressed conditions.
