the study of the structure and function of the human body
Human anatomy and physiology
the scientific discipline that investigates the structure of the body
Anatomy
The word ________means to
dissect, or cut apart and separate, the parts of the body for study
Anatomy
- covers a wide range of studies, including the structure of body parts, their microscopic organization, and the processes by which they develop.
- examines the relationship between the structure of a body part and its function
Anatomy
Two basic approaches to the study of anatomy
systemic anatomy & regional anatomy
the study of the body by systems, such as the cardiovascular, nervous, skeletal, and muscular systems.
Systemic anatomy
the study of the organization of the body by areas.
Regional anatomy
Anatomists have two general ways to examine the internal structures of a living person:
- provide important information for diagnosing disease.
surface anatomy & anatomical imaging
the study of external features, such as bony projections, which serve as landmarks for locating deeper structures
Surface anatomy
involves the use of x-rays, ultrasound, magnetic resonance imaging (MRI), and other technologies to create pictures of internal structures, such as when determining if a bone is broken or a ligament is torn.
Anatomical imaging
The major goals for studying physiology are
(1) to understand and predict the body’s responses
to stimuli
(2) to understand how the body maintains internal conditions within a narrow range of values in the presence of continually changing internal and external environments.
the study of a specific organism, the human, whereas
“cellular physiology” and “systemic physiology” are subdivisions that emphasize specific organizational levels.
Human physiology
The body can be studied at six structural levels:
chemical, cell, tissue, organ, organ system, and organism
- The structural and functional characteristics of all organisms are determined by their chemical makeup
- level of organization involves how atoms, such as hydrogen and carbon, interact and combine into molecules.
Chemical Level
the basic structural and functional units of organisms,
such as plants and animals.
