pineal body
Noun: A small, pinecone-shaped endocrine gland located in the brain. It is situated near the center of the brain, beneath the posterior part of the corpus callosum. Its primary function is the secretion of the hormone melatonin, which helps regulate sleep-wake cycles (circadian rhythms).
The term "pineal body" is used in anatomical, biological, and medical contexts to refer specifically to this gland. It is often discussed in relation to sleep, biological rhythms, and endocrine function. * The pineal body is sometimes called the "third eye" in philosophical and metaphysical traditions due to its central location and light-sensitive function in some species. * A tumor affecting the pineal body can disrupt normal sleep patterns. * Researchers studied the effect of light exposure on the pineal body's melatonin production.

- Epiphysis cerebri: This is the formal anatomical Latin name for the structure.
- Pineal gland (n): The most common contemporary term for the pineal body.
- Melatonin (n): The primary hormone secreted by the pineal body/gland.
