In the HE stained specimens,ghd hair straightener, the cells were round or irregular shape. Nuclear large, round, irregular or lobulated, light color, prominent nucleoli. Weakly basophilic cytoplasm containing a small amount of lipid droplets. In the silver stained specimens, the pineal cells of irregular shape, with projections of varying lengths, protruding end of the enlargement, often beyond perivascular. Electron microscope, the cytoplasm has rough endoplasmic reticulum, Golgi complex and small round secretory granules, granules containing melatonin (melatonin).

Membrane often associated with nerve endings synapse ; near synapses in the pineal cell synapses were seen with the Ministry of synapses with high electron density from the middle of the small rod-like structure and its surrounding vesicles,cheap ghd australia, whose function is unclear. Fewer glial cells, located between the pineal gland cells. In the HE stained specimens, cell body is small, irregular, small nuclei, stained dark. Cells cheap ugg boots protruding ends attached to the pineal gland cells or out into the perivascular space. Electron microscope, the cytoplasm is rich in rough endoplasmic reticulum, free ribosomes and microfilaments and so on.

Composed primarily of calcium phosphate and calcium carbonate. Brain sand usually appear after puberty,ghd sale, the amount increases with age. The functional significance of brain sand unclear, some people think. The number of brain sand secrete hormones may reflect the activities of the past. Mainly from the pre- pineal sympathetic nerve fibers after steadily, mainly limited to perivascular nerve endings gap between the small ends pineal cells, some with cell synapse. Pineal gland function is not yet understood. Generally, the human pineal gland can synthesize, secrete a variety of biological glue and peptides, mainly to regulate the secretion of nerve and reproductive function, and this adjustment has a strong biological rhythm, and the intensity of light.
