Description
Animal bodies represent one of the more complex and perfect systems of nature but despite its complexity and functionality, the control of its basic functions is performed by only two systems: the nervous system and the endocrine system. Reproduction, gestation, muscle contraction, nutrient digestion and absorption, hydroelectrolytic balance, haematopoiesis and so many other bodily functions, are directly or indirectly controlled by these systems. In a simplistic way, we can say that the nervous system is responsible for rapid organic activities, while the endocrine system is responsible for a slower, more durable activity, the metabolic functions of the organism. The endocrine system is essential for growth and development, sexual function, reproductive processes and metabolism.
In the present work the authors describe the main endocrine glands in the dog, namely anterior and posterior pituitary gland, thyroid, parathyroid, pancreas and adrenal glands, referring their location, macroscopic and histologic features, using original figures. Main endocrine hormones and hormonal functions will also be addressed in a simple, straightforward and original manner, using cutting-edge, innovative schemes that will contribute for an easy and direct understanding of the complex endocrine mechanisms.
The endocrine system is often subjected to pathological changes. Improving knowledge in the field of endocrinology will allow for a better clinical approach to animal patients, enhancing, without doubt, the provision of better medical veterinary care and its advancement towards excellence.
