Cortisol secretion is closely regulated by ACTH, and plasma cortisol levels parallel those of ACTH. (oncohemakey.com)
Cortisol secretion is low in the late evening and continues to decline, so around 12.00-1.00 a.m. cortisol levels may be undetectable. (oncohemakey.com)
Cortisol secretion then gradually declines during the day, so values obtained later in the day are lower and at 4 p.m. are approximately half of morning values. (oncohemakey.com)
Responses to stress (e.g., surgery and hypoglycemia) originate in the central nervous system and increase hypothalamic CRH and thus pituitary ACTH secretion. (oncohemakey.com)
