Introduction:
Endocrine glands are collections of specialised cells that
synthesise and store their secretions, and release them directly into
the blood stream. They are sensing and signaling devices located in the
extracellular fluid compartments and are capable of responding to changes
in the environment in order to maintain homeostasis.
The endocrine organs are small compared with other organs,
widely distributed, and connected with one another via the bloodstream.
Many diseaseS of the endocrine glands are characterised
by dramatic functional disturbances and characteristic clinicopathologic
alterations affecting one or several body systems. The affected animal
can be presented because of changes that primarily involve the skin (hair
loss caused by hyperthyroidism), nervous system (seizures caused by hyperinsulinism),
urinary system (polyuria caused by diabetes mellitus, diabetes insipidus
and hyperadrenocorticism)or skeletal system (fractures induced by hyperparathyroidism).
