Explanation- The pineal gland is a small pinecone-shaped mass of glandular tissue found just posterior to the thalamus of the brain. The pineal gland produces the hormone melatonin that helps to regulate the human sleep-wake cycle known as the circadian rhythm.

The 2 main thyroid hormones are T3 (triiodothyronine) and T4 (thyroxine or tetraiodothyronine). T3 and T4 regulate your body’s temperature, metabolism and heart rate. The amount of thyroid hormones secreted is controlled by another hormone, called thyroid stimulating hormone (TSH), which is released from the pituitary gland in your brain.

Ovary gland main hormones are—estrogen and progesterone.

Medulla cells secretes catecholamines epinephrine, norepinephrine, and dopamine.
