Glands are the organs that produce hormones, saliva, tears, enzymes and many others in the body. GH, TSH and PRL are produced by the pituitary gland.
The pituitary gland is an organ that is vital for the regulation of the body's activities and functions. It is also called the master's glands as they majorly regulate the hormone secretions.
It secretes hormones related to reproduction, growth and development, milk secretion, tear formation and many others. It also regulates and commands other glands to release hormones.
It produces and releases growth hormone (GH) for growth and height, TSH for the production and secretion of the thyroxine, triiodothyronine from the thyroid gland, oxytocin for childbirth and prolactin for milk lactation.
Therefore, the pituitary gland produces GH, TSH, oxytocin and PRL.
