What are the 3 types of inclusions? What makes them inclusions?
1. Fat droplet- found in adipocytes, adrenal cortex cells, liver cells.
2. Glycogen granules- storage sites for glucose found mainly in the liver cells
3. Lipofucin granules- in aged, non-dividing cells like neurons and muscle cells. usually golden brown in colors and can be membrane bound because they start as lysosomes but cannot break down any more.
An inclusion is something in the cell usually non-membrane bound with the exception of lipofuscin granules that have no function in the cell and are accumulated metabolites.
