adrenal gland: an endocrine gland located immediately above the kidney. It consists of two portions: a cortex and a medulla. The cortex produces and secretes steroidal hormones, among them cortisol (a glucocorticoid), and weakly active sex hormones. The medulla produces epinephrine and norepinephrine (adrenaline and noradrenaline), catecholamines augmenting sympathetic nervous system arousal.
