SEROUS ACINUS – 4
At an even higher magnification of a pancreas section, you can better observe the of the serous acini.
Watch the acinus at the center of the image, highlighted by a green line. It is surrounded by parts of neighbouring acini.
See how its secretory cells stay very close together to form a small ovoid structure and to organize themselves into ana 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 as well of the other acinar cells. The lumens of the acini are not readibly seen, some are highlighted in green.
The nuclei have prominent nucleoli, a sign that the cells are actively synthesising of molecules, in this case mainly enzymes.
Besides the acini the pancreas contains little endocrine called islets of Langerhans or pancretic islands. They are placed between groups of acini and will be studied later in this Chapter.
