* 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 - Reptiles|calcium]] and [[Phosphorus|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.
