CSP: pituitary hormone that stimulates the secretion of adrenal cortical steroids and induces growth of the adrenal cortex.,MSH: An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).,NCI: A hormone made in the pituitary gland. ACTH acts on the outer part of the adrenal gland to control its release of corticosteroid hormones. More ACTH is made during times of stress.,NCI: A hormone secreted by the anterior portion of the pituitary gland and regulates hormone, primarily cortisol, secreted by the adrenal gland.
