Endocrine glands
- By comparison to mammals the thyroids and parathyroids of lizards may have different morphology. The thyroids are involved in control of ecdysis but the parathyroids have a similar role to the parathyroids of mammals. The thyroids may be single, bilobed or paired and the parathyroids are paired.
- The adrenals are paired and located in the mesorchium or mesovarian and must be avoided during neutering.
- The pancreas is usually attached to the duodenum and may be pale pink in colour. It contains alpha and beta cells that produce glucagon and insulin. The cells are not grouped into islets and diabetes appears to be relatively rare. It is both an endocrine and exocrine organ.
