LaNenitafb8712
The pineal gland contains a number of peptides, including GnRH, TRH, and vasotocin, along with a number of important neurotransmitters such as somatostatin, norepinephrine, serotonin, and histamine but the most important hormone is the melatonin

What is the smallest system in the body?
There is little attention given to the Carotid Body but it is the smallest organ at the size of a grain of rice. The pineal gland--it's 8mm long in human bodies. It's located above the superior colliculus and behind and beneath the stria medullaris. It's also a part of the epithalamus. An organ is a complex structure formed by 2 or more tissues. If we use this definition, then a corpuscle of touch (Meissner's corpuscle) would be an organ and much, much smaller than the pineal gland. A corpuscle of touch consists of nerve endings (dendrites) and a connective tissue covering. Another candidate for the smallest organ would be a taste bud, but I think corpuscles of touch would be smaller. A more appropriate question might be, "What is the smallest organ that is part of the gross anatomy of the human body." The pineal gland might be the correct answer for this.

What is the smallest living thing in your body?
The pineal gland (also called the pineal body or epiphysis, is also called third eye) is a small endocrine (smallest)gland located in the brain. It is located near the center of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join.

Smallest part of your body?
That question should probably be more limited, something like, what is the smallest bone in the human body (one of the inner ear bones), or what is the smallest organ (possibly the pineal gland) rather than what is the smallest part, because everything in the universe is ultimately made of the same small parts, which are sub-atomic particles. From the perspective of a physicist, a quark would be the smallest part.
