English: Fig. 3.1 Position of the parathyroid glands
This is a composite picture of all the glands found in 25 cadavers "plotted on a thyroid
gland of average size and shape. The upper brackets indicate approximately the upper,
middle and lower thirds of the thyroid; the lower bracket the space below the
thyroid gland, the numbers giving the counts of the parathyroids within each
bracket. The parathyroids are represented as if the thyroid were transparent.
An attempt has been made to indicate the parathyroids which might be called
'superior parathyroids' in outline and 'inferior parathyroids' in black. Those glands
which could not be classified either by location or by being one of a pair are cross-
hatched" (Heinbach 1933).
