Because insulin receptors have been desensitized to insulin, the addition of more insulin will not have any effect. This is why Type II Diabetes is much more difficult to treat than Type I. The recommended course of action for individuals with Type II diabetes is to eat healthy and exercise.

The adrenal gland is almost certainly responsible for your reaction, as this gland contains the adrenal medulla, which is capable of releasing epinephrine. During stressful situations, the sympathetic nervous system triggers the fight-or-flight response. During this response, sympathetic nerves stimulate the adrenal medulla, which then releases epinephrine. Epinephrine raises blood sugar levels and increases blood pressure, brain oxygen consumption, and heart rate. It prepares an individual to either fight a threat (such as a dog), or run away from it.

The anterior pituitary is capable of releasing a number of hormones including growth hormone, thyroid-stimulating hormone, and prolactin.

The pineal gland is involved in biorhythms and sleep patterns. 

The adrenal cortex is stimulated by adrenocorticotropic hormone and releases corticosteroids in response to long-term stress, such as sleep or food deprivation.

The anterior pituitary is responsible for releasing a large number of hormones; however, oxytocin is released by the posterior pituitary. Two of oxytocin's most important functions include stimulating uterus contractions and stimulating milk production by the mammary glands. 

Prolactin stimulates milk release from the mammary glands.

Thyroid-stimulating hormone stimulates the release of hormones from the thyroid gland.

Growth hormone stimulates the growth of bones and stimulates the liver to release insulin-like growth factors.

It is important to note that at least one hormone from the hypothalamus is used to regulate each of the hormones released by the anterior pituitary—for example, the anterior pituitary gland will only release prolactin if the hypothalamus releases prolactin-releasing hormone. 

A hormone is a chemical formed in one organ and carried by the blood to stimulate or inhibit the function of another organ.

Enzymes are protein molecules that carry out catalytic functions. Electrolytes are simply ions dissolved in solution. Second messengers are relay molecules between a signal and its ultimate effect, such as the molecules that carry signals from the cell membrane to the nucleus to affect transcription. Platelets are cell fragments in the blood that help form clots to heal injuries.

The hormones secreted by the pituitary gland are FLAT PEG: Follicle-stimulating hormone, luteinizing hormone, adrenocorticotropic hormone, thyroid-stimulating hormone, prolactin, endorphins, and growth hormone. Testosterone is produced in the testes in males, and in the adrenal gland in both males and females. Insulin is produced by the pancreas. Estrogen is produced by the ovaries in females, and in the adrenal gland in both males and females.
