* By comparison to mammals the '''thyroids and parathyroids''' of lizards may have different morphology. The thyroids are involved in control of [[Lizard Shedding|ecdysis]] but the parathyroids have a similar role to the parathyroids of mammals (control of plasma calcium and phosphorus levels). The thyroids vary with the species and may be single, bilobed or paired and the parathyroids are paired. Nutritional and renal secondary hyperparathyroidism are commonly diagnosed diseases in captive reptiles.

* The '''adrenals''' are paired and located in the mesorchium or mesovarium and must be avoided during neutering.
