where is the pineal gland located in the body
Pineal gland The pineal gland is a small endocrine gland in the brain of animals with backbones. The pineal gland produces melatonin, a serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. The shape and size of the gland resemble a pine cone from which it derived its name.[1] The pineal gland is located in the epithalamus, near the center of the brain, between the two hemispheres, tucked in a groove where the two halves of the thalamus join.[2][3] It is also called the conarium, kÃ´narion or epiphysis cerebri. The pineal gland is included among a group of specialized neuroendocrine brain structures called the circumventricular organs.[4]
