Flashcards in Chapter 1.2 Definition of Anatomy Deck (28):

Anatomy is

The study of structure


The word anatomy is derived from Greek and means

To cut apart


Anatomists which are scientists who study anatomy, examine

The relationships among parts of the body as well as the structure of individual organs


Physiology is the

Scientific discipline that studies the function of body structures


The discipline of anatomy is a broad field that can be divided into two general categories which are?

Microscopic anatomy and Gross Anatomy


Microscopic Anatomy examines

Structures that cannot be observed by the unaided eye


The microscope has evolved from the

Primitive form first developed in the seventeenth century to a modern microscope


Specialized subdivisions of microscopic anatomy are defined by

The dimensional range of the material being examined


What are some examples of microscopic anatomy

1.) Cytology: Cellular anatomy, is the study of single body cells and their internal structures
2.) Histology: Is the study of tissues. It takes a wider approach to microscopic anatomy by examining how groups of specialized cells and their products function for a common purpose


Gross Anatomy is

Also called macroscopic anatomy which investigates the structure and relationships of large body parts that are visible to the unaided eye, such as the intestines, stomach, brain, heart, and kidneys


In macroscopic investigations, preserved specimens or their parts are often

Cut open (dissected) for examination


Name the several approaches to gross anatomy

1) Comparative anatomy
2) Developmental anatomy
3) Embryology
4) Regional anatomy
5) Surface anatomy
6) Systemic anatomy


Name the several specialized branches of anatomy that focus on the diagnosis of medical conditions or the advancement of basic scientific research

1) Pathologic anatomy
2) Radiographic anatomy
3) Surgical anatomy


Comparative anatomy examines

The similarities and differences in the anatomy of species


Developmental anatomy investigates

The changes in structure within an individual from conception through maturity


Embryology is

Concerned specifically with developmental changes occurring prior to birth


Regional anatomy examines

All the structures in a particular region of the body as one complete unit


Give an example of regional anatomy

The skin, connective tissue and fat, bones, muscles, nerves and blood vessels of the neck


Surface anatomy examines

Both superficial anatomic markings and internal body structures as they relate to the skin covering them


Who uses surface anatomy

Health care providers use surface features to identify and locate specific bony processes as joints as well as to obtain a pulse or a blood sample from a patient


Systemic anatomy studies

The gross anatomy of each system in the body


Give an example of systemic anatomy

Studying the urinary system would involve examining the kidneys, where urine is formed, along with the organs of urine transport (ureters and urethra) and storage (urinary bladder)


What are the several specialized branches of anatomy that focus on the diagnosis of medical conditions or the advancement of basic scientific research?

1) Pathologic anatomy
2) Radiographic anatomy
3) Surgical anatomy


Describe Pathologic anatomy

It examines all anatomic changes resulting from disease


Describe Radiographic anatomy

It studies the relationships among internal structures that may be visualized by specific scanning procedures, such as ultrasound, magnetic resonance imaging (MRI), or x-ray


Describe Surgical anatomy

It investigates the anatomic landmarks used before and after surgery


Give an example of surgical anatomy

Prior to back surgery, the location of the L4 vertebra is precisely identified by drawing an imaginary line between the hip bones. The intersection of this line with the vertebral column shows the location of L4


Anatomic studies are ongoing, and the success of the discipline depends upon the

Precise observation, thorough description, and correct use of terminology
