Explanation:

Cortisol is a hormone, not a neurotransmitter. The adrenal glands release cortisol in response to stress. The pancreas releases insulin and glucagon. The pituitary gland releases hormones like growth hormone and ACTH (which signals the adrenal glands to release cortisol, but the cortisol itself comes from the adrenals). The thyroid gland releases thyroid hormones like thyroxine.

Answer:

A hormone released by the adrenal glands in response to stress.
