Some glands have a well defined, lobular structure, strands of connective tissue separating the groups of parenchymal cells. The pineal gland or epiphysis cerebri is a small neurosecretory organ in the brain containing secretory neurons (pinealocytes), interstitial glial cells, and axons that communicate with other parts of the brain. The lumen is occluded except at the base of where the evagination started.
