:If a β₂ receptor is bound this will result in hyperpolarisation of the cell which will cause dilation of the bronchioles of the lung.

'''Dopamine''' is involved in motivation as well as love and addiction. It is effectively a 'reward system' for the brain. Dopamine also affects the way in which the basal ganglia of the brain affect our movements and a shortage of dopamine can result in diseases such as Parkinson's. Dopamine is the primary neuroendocrine regulato r of [[Lactation - Endocrine Control - Anatomy & Physiology|'''prolactin''']] from the anterior [[Pituitary Gland - Anatomy & Physiology|pituitary gland]]. It is thus often called prolactin-inhibiting hormone in reproduction. Dopamine produced by the [[Hypothalamus - Anatomy & Physiology|hypothalamus]] is secreted via the hypothalamo-hypophysal blood vessels which supply the pituitary gland. Secretion of prolactin via lactotrope cells within the pituitary is inhibited by dopamine.

'''Serotonin''' is involved in emotions, mood, sexuality, consciousness, sleep and thermoregulation. Serotonin is utilised by the central nervous system and the gastro-intestinal system. Serotonin has also been linked to mechanisms controlling pulmonary and cerebral vascular vasoconstriction.
