Corpora arenacea
Corpora arenacea, also known as brain sand, are calcified structures that appear in the pineal gland and other areas of the brain. These structures are composed of calcium phosphate, calcium carbonate, magnesium phosphate, and ammonium phosphate.
Overview[edit | edit source]
Corpora arenacea are small, calcified deposits that are found in the pineal gland and other parts of the brain. They are also known as brain sand or acervuli and are composed of calcium phosphate, calcium carbonate, magnesium phosphate, and ammonium phosphate.
Formation and Composition[edit | edit source]
The exact process of formation of corpora arenacea is not fully understood. However, it is believed that they are the result of age-related calcification of the pineal gland. The composition of these structures is primarily calcium phosphate and calcium carbonate, with smaller amounts of magnesium phosphate and ammonium phosphate.
Clinical Significance[edit | edit source]
While the presence of corpora arenacea is generally considered a normal part of aging, excessive amounts can be associated with certain medical conditions. For example, a high concentration of corpora arenacea has been observed in patients with Alzheimer's disease. However, it is unclear whether this is a cause or effect of the disease.
