Question

Quizplus · Accepted Answer

Serotonin is a neurotransmitter. Neurotransmitters are chemical messengers within the brain that allow communication between nerve cells. Serotonin is involved in regulating mood, stress and anxiety, sleep, overall happiness, and appetite. Low serotonin levels have been linked to depression.
Dopamine is a neurotransmitter that is involved in regulating motivation, euphoria (pleasure), and fine motor function (the coordination of small muscle movements).
Antidiretic hormone (also called vasopressin) is involved in regulating urine output and maintaining osmolarity (the electrolyte-water ratio in your body).
Oxytocin is involved in stimulating the uterine muscles to contract during childbirth and promoting lactation.
NOTE 1: Oxytocin and antidiuretic hormone are both hormones and are not neurotransmitters. They are both produced by the hypothalamus gland and stored in the posterior pituitary gland for later release.
NOTE 2: Neurotransmitters are different from hormones because hormones are secreted by endocrine glands directly into the blood, whereas neurotransmitters are messages between nerve cells in the brain.
