Animal anatomy, histology, pathological anatomy

Internal inspection.To open cavities and remove organs, the animal corpse is placed in a dorsal position. For these purposes, after removing the skin, the muscles connecting the shoulder blades to the chest and the pelvic limbs to the body of the animal are cut, the hip joints are opened and the corpse is fixed in the dorsal position. The abdominal cavity is opened and examined (in the middle and posterior thirds of the cavity there are loops of the small intestine, the diaphragm is at the level of the 7th rib). Then the organs of the chest cavity and neck are opened and examined. The chest cavity is opened with costal scissors along the osteochondral joints, separating the breast bone.
The organs of the oral cavity, neck, chest, abdominal and pelvic cavities are removed as a single complex, preserving the anatomical connections between them (according to G.V. Shor’s method) or, in necessary cases (in particular, when dissecting large animals) with partial dissection of the organ complexes, taking into account the anatomy – physiological and systemic connections.


Necropsy of rabbits
Rabbits belong to the class of mammals, the order Lagomorpha. Many breeds of rabbits have been bred for meat, fur, and fluff (white giant, Angora rabbit, etc.).


OPTION TECHNIQUE
The rabbit's corpse is strengthened in the dorsal position. Remove the skin. External examination during the opening of body cavities is carried out in the usual manner.



Fig. 315. Position of the abdominal organs of the rabbit.

The spleen is separated together with the omentum from the stomach, two ligatures are placed on the esophagus at the entrance to the stomach, the esophagus is cut between the ligatures, as well as two ligaments connecting the stomach with the diaphragm and the liver.

The stomach is separated along with the small and large intestines.
Other organs are removed in the usual way.
Pay attention to diseases that are often found in rabbits (viral rhinitis, eimeriosis, myxomatosis, spirochetosis, toxoplasmosis, pasteurellosis, staphylococcosis, necrobacteriosis, tympany, corynebacteriosis, tularemia, pneumonia, gastroenteritis, nutritional dystrophy, etc.).
