Pancreas

 Islets of Langerhans are the lighter staining groupings of cells.  Pancreatic ducts are in the center and the edge.

 Islet of Langerhans which produce both   glucagon and insulin

Islet of Langerhans  produce both glucagon and insulin

http://w3.ouhsc.edu/histology/Text%20Sections/

The pancreas has both  endocrine and exocrine cells

Pancreatic ducts stain lighter and are sometimes confused with isles of Langerhans

http://www.lab.anhb.uwa.edu.au/mb140/CorePages/

The ducts have open lumens whereas the isle of Langerhans are just circular groupings of cells

 Colloid contains thyroglobulin and follicular cells  secrete thyroid hormones

Follicular cells secrete thyroid hormones.

 Colloid and follicles are divided by connective tissue and parafollicular cells

The parathyroid gland is made of with chief cells and oxyphil cells.

http://www.lab.anhb.uwa.edu.au/mb140/CorePages/

Oxyphil cells produce parathyroid hormone

Thyroid and Parathyroid

The thyroid has follicles and the parathyroid is made of  denser tissue.

 The anterior pituitary (adenohypophysis) is also know as the Pars distalis and the posterior pituitary (neurohypophysis) is also known as the Pars Nervosa

http://w3.ouhsc.edu/histology/Text%20Sections/

There is a division  between the anterior pituitary (adenohypophysis) or the pars distalis and the posterior pituitary (neurohypophysis) or  pars nervosa

The thymus gland releases thymopoietins and thymosin to activate T-cells.  It is usually considered an gland of the lymphatic system.  I
