Terms to Know
  • Adrenal Cortex

    The outer covering of the adrenal gland that secretes hormones that regulate body mineral levels, metabolism and aid in the production of sex hormones.

  • Adrenal Medulla

    The adrenal medulla releases hormones called catecholamines (adrenaline) that elevate our metabolism in response to stress. The adrenal medulla is controlled by the sympathetic nervous system (SNS).

  • Epinephrine

    Classified as a catecholamine (adrenaline) and is secreted from the adrenal medulla; epinephrine is found in higher amounts in the blood than its counterpart norepinephrine.

  • Glucocorticoids

    Hormones that affect glucose metabolism of the body, the most abundant one being cortisol a.k.a. the stress hormone.

  • Gluconeogenesis

    The process of converting amino acids and lipids into glucose, this process takes place in the liver.

  • Hypoglycemia

    The clinical term for low blood sugar.

  • Mineralcorticoids

    Hormones that maintain mineral homeostasis; aldosterone is a hormone that stimulates the kidneys to retain sodium.

  • Norepinephrine

    Classified as a catecholamine (adrenaline) and is secreted from the adrenal medulla; norepinephrine is found in lower amounts in the blood than its counterpart epinephrine.
