Urinary System. In the first part physiopathology considerations associated to morphological changes of renal parenchyma and lower urinary tract are treated. Then anomalies of development, regressive changes, inflammatory lesions and neoplasia of kidney and lower urinary tract are extensively discussed. Urolithiasis and hydronephrosis are also treated.

Hematopoietic System (IS). In the first a brief anatomical distribution of IS and turnover mechanisms of hematopoietic cells will be reviewed. After that, involution/regressive and reactive processes of the bone marrow and thymus will be treated.
Then the course will progress to the description of macroscopic pattern of regressive processes, vascular disorders, reactive hyperplasia, and inflammatory diseases of spleen and lymph nodes. When appropriate, inflammatory lesions of hematopoietic tissues will be included and discussed within systemic or multiorganic diseases. A session apart will be dedicated to neoplasia of hematopoietic tissues.
Central and Peripheral Nervous System (CNS - PNS). In the first part, basic lesions and histological patterns of the nervous tissue lesions will be treated. The criteria for CNS and PNS gross diagnosis will be made from them. In the second part of the course, we will proceed to illustrate histological and distribution patterns of lesions applied to different classes of neurological diseases, specifically referred to species: vascular, infectious/infective, traumatic, toxic-metabolic, neoplastic, and neurodegenerative diseases.
Muscle System (MS). Basic lesions referred to skeletal muscle will be treated. The criteria for gross anatomy diagnosis will be made from them and applied to the different classes of domestic animal myopathies. Then, lesions and their physiopathological implications will be discussed for infectious/inflammatory myopathies, metabolic/endocrine primary or secondary myopathies, hereditary myodystrophies, and neuromuscular transmission disorders.
Endocrine System (ES). The most common gross anatomy patterns for hypophysis, adrenal glands, chemoreceptor organs, thyroid and parathyroids, and endocrine pancreas occurring in development disorders, regressive and progressive processes, inflammatory and neoplastic diseases will be treated in domestic animals. A wide physiopathology discussion will be related with morphological disorders of endocrine glands.

Educational objectives
The course gives information necessary for a morphological and pathogenetic study of lesions. Moreover, it gives a diagnostic algorithm aimed to identify the cause/effect relationship, including physic and biological etiology agents, referred to different organs and systems. Finally, based on physiopathologic considerations, the course indicates prognostic evaluations referred to the pathological patterns.
The course is compliant with the teaching aims (SUA A4.a) and employment outlets (SUA A2.a) of the Degree Course referred to physiopathology, etiopathogenesis, diagnosis and therapy of the main diseases of domestic animals, alone or in group.

Teaching methods
Il corso è organizzato nel seguente modo:
- lezioni frontali in aula (45h) su tutti gli argomenti del corso
- esercitazioni Pratiche Comuni (11h) eseguite in sala anatomica (max 15 studenti suddivisi in gruppi da 4 studenti) alternate ad esercitazioni su quadri anatomopatologici illustrati mediante diapositive, attraverso discussione interattiva
- Clinical Rotation (9h) presso il Servizio di Patologia Veterinaria. Durante la Clinical Rotation lo studente sarà impegnato nell’esecuzione di necroscopie, compilazione del foglio di lavoro e diagnosi morfologica, trimming dei campioni anatomici, esecuzione di colorazioni istologiche e lettura di preparati istologici/citologici, a seconda delle attività di servizio.
Le attività pratiche svolte in Sala Settoria e nei laboratori del Servizio di Patologia Veterinaria sono regolate da procedure disponibili presso la pagina UniStudium del corso in questione. Il calendario delle attività teoriche e pratiche è disponibile sul sito web del dipartimento di Medicina Veterinaria nella sezione Didattica.
