INTRODUCTION TO ANATOMY

The term "anatomy" comes from the Greek. anatome, which means “dissection”, “cutting apart”. The main method of investigation in anatomy is the preparation, i.e. dissection of an animal's body. Anatomy is the science of the form and structure of the organism in the process of its development and adaptation. 1) Idealistic stage – the era of the Ancient World and is associated with the names of the ancient Greek philosophers Plato (427-347 BC) and Aristotle (384-322 BC). 2) Descriptive stage – the Middle Ages, and its typical representatives were Pierre Belon (1517-1564), who tried to match the skeleton of a bird and a man; Thomas Willis (1622-1675) (the founder of comparative anatomy); Geoffrey St. Hilaire (1772- 1844. 3) Microscopic stage is associated with the discovery in 1665 of Robert Hooke in the structure of plants ”cell", later Marcello Malpighi (1628-1694), Anthony van Leeuwenhoek (1632-1723) described the cellular structure of animals. It gave rise to such sciences as "cytology" and "histology." 4) Evolutionary stage relates to the theory of Charles Darwin (1809-1882) on the ways of evolution of the animal world. 5) Experimental stage – the end of the 19th century and is associated with the works of PF Lesgaft (1837-1909) on the mutual dependence of form and function.

ANOMALY is an insignificant deviation from the generally accepted norm, which does not affect the function of the organ. RUDIMENT (Latin Rudimentum - the first principle) - simplified, underdeveloped structures that have lost their importance in the body in the process of phylogenesis. ATAVISM (Latin Atavus - the ancestor) is the appearance in some individuals of the organs that existed in distant ancestors and were lost in the process of evolution.

OBJECTS

  1. horse domestic (equus caballus);

GROUPS OF SYSTEMS AND APPARATUS

  1. The somatic group – form the walls of the body - soma (lat.soma)
  2. The visceral group – make up internal organs (Latin Viscera)
  3. The integrating group – ensure the integrity of the organism and its connection with the environment **BASIC LAWS OF BIOLOGICAL DEVELOPMENT
  4. The law of historical development.**
  • There is a constant differentiation of cells and tissues with their simultaneous integration. -Each organ has several functions, but one of them is the main one. -If you change the LIFE CONDITIONS, you can change the main function to a secondary one and vice versa. -In the body, there are always two opposing processes: progressive development and regressive development. -All changes in the body occur correlatively, i.e. changes in some bodies inevitably lead to changes in other bodies. 2) The law of the unity of the organism and environment. It is achieved in 4 ways: a) by aromorphosis; b) by idioadaptation; d) by general degeneration. **3) The law of the integrity and indivisibility of the organism
  1. The law of unity of form and function.
  2. The law of heredity and variability.
  3. The law of homologous series
  4. The law of saving material and space.
  5. The basic biogenetic law (Baer-Haeckel).**

GENERAL PRINCIPLES OF THE STRUCTURE OF THE ANIMAL BODY

  1. Bipolarity (uniaxiality) is the presence of two poles of the body: the head (cranial) and the caudal (caudal).
  2. Bilaterality (bilateral symmetry) is expressed in similarity in the structure of the right and left halves of the body, so most organs are paired (eyes, ears, lungs, kidneys, thoracic and pelvic limbs).
  3. Segmentarity (metamerism) - the adjacent parts of the body (segments) are close in structure.
  4. The law of tube construction. All the systems of the body develop in the form of tubes.
  5. Most unpaired organs are located along the main body axis.
