Pineal Gland Structure
The pineal gland is located at the geometric center of the human brain. The pineal gland is uniquely isolated from the blood-brain barrier system, so it receives a higher percentage of blood flow than any other part of the body, except the kidneys. The pineal gland is also known as the glandula pinealis, pineal body, epiphysis cerebri, epiphysis, conarium or the “third eye”. Moreover, the pineal gland is considered by many to be our biological Third Eye, the “Seat of the Soul,” or the “Epicenter of Enlightenment.” The upper portion of the pineal body is the optic, or eye. This is referred to as the All-Seeing eye. It is likened to the flame of a candle, which relates to the Bilblical reference of the candle which gives light to the whole house. This parable can be interpreted as the pineal being the source of illumination of the body.
The pineal gland is our masculine spiritual organ. The lower portions of this organ are named corpora quadrigemina, which is Latin for “quadruplet bodies.” The copora quadrigemina are the four colliculi—two inferior and two superior, also known as two nates (buttocks) and two testes (testicles).
The pineal gland’s function in the body is not clearly understood by neuroscientists. Nonetheless, here is a brief summary of some known functions. The pineal gland modulates our wake-sleep patterns and circadian rhythms as well as photoperiodic/seasonal functions. The pineal gland also plays a role in regulating female reproduction and sexual maturation.
