Microstructural aspect of pineal body: pinealocytes population

Haemangiopericytoma of the pineal body.

The pinealocytes of the human pineal gland: A light and electron microscopic study.

The pinealocytes of the pineal gland of children and adults were studied at both light and electron microscopic levels. The pinealocytes were classified into light and dark pinealocytes on the basis of their shape, nuclear infolding, cytoplasmic contents and staining density. The light pinealocytes outnumber the dark pinealocytes and both of them have thin processes. The light pinealocytes have...

Modulation of Pineal Melatonin Synthesis by Glutamate Involves Paracrine Interactions between Pinealocytes and Astrocytes through NF-κB Activation

The glutamatergic modulation of melatonin synthesis is well known, along with the importance of astrocytes in mediating glutamatergic signaling in the central nervous system. Pinealocytes and astrocytes are the main cell types in the pineal gland. The objective of this work was to investigate the interactions between astrocytes and pinealocytes as a part of the glutamate inhibitory effect on me...

Studies on the function of the pineal body.

The pineal body was for a long time looked upon as a functionless remnant and from a phylogenetical point of view was accepted as a rudiment of the third eye, which is, at the present time, only found in hatteria punctata. As far as is known an epiphysis is present in all ver tebrates with the exception of mixinoids and crocodilia. In man the pineal body is pear shaped, lies just beneath the sp...
