SEROUS ACINUS – 4
At an even higher magnification of a pancreas section, you can better observe the characteristics of the serous acini already pointed out in the previous pages.
Watch the acinus in the center of the image, highlighted by a green line. It is surrounded by parts of neighbouring acini.
See how the secretory cells come close together to form a small ovoid structure and to organize themselves into an acinus. Imagine that this structure is, in fact, three-dimensional.
The acinar cells are columnar or pyramidal. Some become highlighted by a black outline. Place and remove the mouse several times to recognize the shape of these and of the other cells present in the image.
The nuclei have prominent nucleoli, a sign that the cells are involved in synthesis of molecules, in this case mainly of proteins.
There are also other structures in the pancreas that are cordonal endocrine glands, called islets of Langerhans. These islets of cells are located inside the pancreas between the acini. These endocrine glands will be shown later in this Chapter.
