Introduction to Anatomy.

-

                

Anatomy:

 

Origin:

        Anatomy is a combination of two words; a Greek" word ANA (apart) and "Latin" word TOMY (cut).

 

Definition:

        It is the branch of biological science that deals with the structure and form of animals. Anatomy includes the study of shape, weight, color, texture, and relative position of various parts and organs of the organisms when they are in a state of normal health.

 

Branches of Anatomy:

        The main branches of anatomy are:

1)Gross Anatomy/Macro Anatomy:

        It is the study of structures which can be dissected and seen with the help of the naked eye.

2)Histology/Micro Anatomy:

        The study of minute structures that are too small to be seen without a microscope.

3)Cytology/Ultrastructural Anatomy:

        It is the study of minute structures with even greater detail, with the help of an electron microscope.

4)Applied Anatomy:

        Study of the practical application of anatomical knowledge to the diagnosis and treatment.

5)Morbid Anatomy/Pathology:

        It is the study of the diseased structures of an organism.

6)Teratology:

       Teratology is the study of abnormal development of an individual.

7)Developmental Anatomy:

        The study of the development of an individual from a zygote to an adult.

8)Embryology:

      It is the study of structures from egg to birth.

9)Comparative Anatomy:

      It is the study of the comparison of the structures of different animals.

10)Morphological/Philosophical Anatomy:

       The study of generalization made on an outer form and inner structures.

11)Phylogeny:

      It is the study of the evolutionary history of species.

12)Special Anatomy:

     It is the study of the structure and form of a single type or specie.

 

Planes of the body:

Definition:

       A plane is an imaginary line along which any two points can be connected and cut in a straight line.

 

Types of planes:

1)Median Plane:

             The plane that divides the body longitudinally into left and right equal halves.

2)Sagittal Plane:

            The plane that divides the body into two unequal right and left halves, parallel to the median plane.

3)Dorsal Plane:

            A plane that runs at the right angle to the median and transverse planes and divides the body into dorsal and ventral halves.

4)Transverse Plane:

           The plane that is perpendicular to the long axis of the body. It is at a right angle to both dorsal and median planes. It cuts the body into cranial and caudal parts.

                                                       

Benefits of Anatomy:

  • It gives an idea of the shape, form, structure, and relative position of the various organs and tissues.
  • Anatomy helps in understanding the function of various parts, their correlation and coordination, and their physical and functional relationship.
  • When normal shape, structure, and function of organs are known, any change from this normal can be recognized with greater ease. Thus it helps in the diagnosis of the diseased state.
  • A good grasp of anatomy gives much help and confidence to a surgeon.
  • It facilitates the administration of drug efficiency.
  • It helps in devising the ways and means for the collection of different samples that are required for a definite diagnosis.
