Classification of Domestic Animal Anatomy

Mainly engaged in the study of gross anatomy. Generally, according to the organ function, it is divided into systems such as coat, movement, digestion, respiratory (livestock), urinary, reproductive, cardiovascular, endocrine, nervous and sensory organs and described, so it is also called systemic anatomy or narrative anatomy. On the basis of systematic anatomy, a comprehensive description of the comprehensive relationship between all the structures of various parts of the body from the outside to the inside is called regional anatomy. Describing the anatomy of specific parts and providing theoretical knowledge for internal medicine, surgery and diagnosis is called applied anatomy. Other branches include experimental anatomy, neuroanatomy, theoretical anatomy, functional anatomy, X-ray anatomy and surface anatomy. Body surface anatomy studies the projection position of various organs and internal organs on the animal body surface, also known as projection anatomy. The study of the three-dimensional structure of organs between gross anatomy and microscopic anatomy is called macro-microanatomy. The commonly used research method of livestock anatomy is to use knives, scissors, tweezers, saws, etc. to cut livestock carcasses and observe them with the naked eye or with the help of a magnifying glass. The pipeline system in the corpse can be filled with colored liquid injection, or the organs and tissues of the corpse can be made transparent before observation; it can also be filled with acid- and alkali-resistant substances such as rosin wax and plastic, and the mold can be studied after corrosion. In addition to observing bones in the body, X-ray photography can also be used with various contrast agents to observe joint cavities, blood vessels or lymphatic vessels. Neuroanatomy can use special methods, such as neuritis method, horseradish peroxidase (HRP) method, etc., to trace nerve fibers and their interconnections.
