Corpora amylacea
Corpora Amylacea
Corpora Amylacea (pronunciation: /kɔːrˈpoʊrə æmɪˈleɪsiːə/), also known as corpora arenacea or brain sand, are small, round, hyaline masses found in various parts of the body, particularly in the central nervous system and in the prostate gland.
Etymology
The term "corpora amylacea" is derived from the Latin corpora, meaning "bodies", and amylacea, meaning "starchy". This refers to their appearance under a microscope, which is similar to that of starch granules.
Description
Corpora amylacea are typically 10-50 micrometers in diameter and are composed of a dense core surrounded by concentric layers. They are often found in the brain, spinal cord, pineal gland, lungs, and prostate gland. Their exact function is not well understood, but they are believed to be a product of normal aging and are more common in older individuals.
