| Other hormones that influence blood sugar levels are cortisol, growth hormone and catecholamines. |
| The tyrosine derivatives are the thyroid hormones, and the catecholamines which are produced in the medulla of the adrenal glands. |
| Kubby's tumour releases, in excess quantities, hormones normally found in the adrenal gland that are called catecholamines. |
| Cocaine blocks the reuptake of catecholamines presynaptically. |
| Dopamine is the most abundant chemical in a class of neurotransmitters called catecholamines. |
| Activation of the adrenergic system triggers the release of catecholamines, which stimulate contractility, heart rate, and blood pressure. |
