Pineal gland reticular fibres, light micrograph. The parenchyma of the adult pineal gland is often organized into rounded units surrounded by connective tissue septa. They are the (incorrectly) called lobules. Each lobule is surrounded by a basement membrane that separates it from the neighbouring connective tissue septum. Some of these septa show signs of fibrosis, with development of numerous collagen fibres that appear with a reddish-brown colour in the image. Parenchymal cells, pinealocytes and glial cells are located in the lobule. Silver method for demonstration of reticular fibres in paraffin sections.
