Final answer:
Hormone synthesis and release are controlled by humoral, hormonal, and nervous system stimulation. Humoral stimulation responds to changes in blood constituents, hormonal stimulation is a result of one hormone influencing another's release, and nervous system stimulation involves direct neural influence on hormone release. The option involving bacterial release is incorrect.
Step-by-step explanation:
The ways to control hormone synthesis and release are through humoral stimulation, hormonal stimulation, and nervous system stimulation. Humoral stimulation involves changes in extracellular fluids, such as blood or ion concentrations, that trigger hormone release. Hormonal stimulation occurs when one hormone signals the release of another hormone, such as the anterior pituitary releasing thyroid-stimulating hormone (TSH) which then stimulates the thyroid gland to produce T3 and T4. Nervous system stimulation is when the nervous system directly signals endocrine glands to release hormones, like in the case of stress causing the adrenal medulla to release epinephrine and norepinephrine.
C. Bacterial release is not a recognized mechanism for the control of hormone synthesis and release in the human endocrine system.
