Back 1

This is the pituitary gland. We know this because it is split into two obvious parts. The posterior pituitary is on the left, and stains a relatively uniform bland color. The anterior pituitary is on the right, and stains in variegated colors, usually red, blue, and clear.

This is the pituitary gland. We know this because it is split into two obvious parts. The posterior pituitary is on the lower left, and stains a relatively uniform bland color. The anterior pituitary is on the top right, and stains in variegated colors, usually red, blue, and clear.

Back 3

This the anterior pituitary gland. We know this because it is "speckled" with lots of things (also, it usually stains in variegated red, blue, and clear coloration). The red cells are acidophils (which produce GH and Prolactin) the blue are basophils (which produce hormones that go to other glands - TSH, HGTH, FSH, and LH) and the clear or whitish are chromophobes, which produce no hormones.

This is the posterior pituitary gland. The cells are relatively uniform light redish-blue (called ptuicytes) and don't make any hormones.

The is the thyroid gland. You can see big rings of simple cubiodal epithelium; this is a distinctive look for thyroid slides. The rings are called follicles. Cells that make up the ring are called follicular cells (which make T3 and T4), cells between the rings are called parafollicular cells (which make calcitonin). The "goop" in the center of the ring, where there is no cell is called thyroglobulin.

This is the parathyroid gland. The key to identifying a parathyroid gland is the nearly uniformly distributed "dots". The parathyroid makes PTH, in the chief cells. The other cells present are oxyphylls (no visual identification for cell types).

This is the adrenal gland. It has clear layers or rings. The three layers, from the outer adrenal cortex to the inner medulla (4, "speed" produces epinephrine), left to right in this picture, are: Zona Glomerulosa (1, globy cells, "salt", produces aldosterones/mineralcorticoids), Zona Fasiculata (2, stringy cells, "sugar", produces hydrocortisone/glucocorticoids), Zona Reticularis (3, globy cells again, "sex", produces aldosterone, progesterone).

This is the pancreas. The identifying feature is the islets of Langerhans present (lighter or darker patches that look a bit like the slide has water spots on it). Both alpha cells (which produce glucagon) and beta cells (which produce insulin) are present in these islets of Langerhans. Cells outside the islets are called acanar or acini.
