Endocrine glands are glands that secrete their product (hormones) directly into the blood rather than through a duct. This group contains the glands of the Endocrine system. The main Endocrine glands include the pituitary gland, the pancreas, the gonads, the thyroid gland and the adrenal glands. Other organs which are not so well known for their endocrine activity include the stomach, which produces such hormones as ghrelin.
the others who have answered this are partially wrong. though there is a medulla in the brain (medulla oblongata), there is another one associated with the endocrine system. the adrenal glands are split into the adrenal medulla and the adrenal cortex. the adrenal medulla produces epinephrine and norepinepherine.
