Q

Pineal gland

A

A small endocrine gland in the brain of most vertebrates. The pineal gland produces melatonin, a serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. The shape of the gland resembles a pine cone, which gives it its name. The pineal gland is located near the center of the brain, between the two hemispheres, tucked in a groove where the two halves of the thalamus join.
