Test #1 - Class 1: Introduction to A&P, Directional and Regional terms Flashcards
Definition: Anatomy
The study of the structure of the human body.
Anatomy or structure often defines physiology.
Definition: Physiology

Anatomy or structure often defines physiology.
How many Levels of Organization?
6
Chemical Level
Takes various atoms and combines them together to make molecules.
Cellular Level
The combination of various molecules.
Tissue Level
Combining similar cells together to perform a function for the body.
Organ Level
Combination of two or more types of tissue together to perform a function for the body.
e.g. gall bladder, kidneys, heart
System Level
Combination of organs together to perform a function for the body.
Organism Level
The highest level of organization. The combination of all 11 organ systems working together to promote life.
What are the 6 Levels of Organization?
- Chemical; 2. Cellular; 3. Tissue; 4. Organ; 5. System; and 6. Organism
How many Necessary Life Functions?
8
What are the 8 Necessary Life Functions?
ESSAY QUESTION: BE ABLE TO LIST AND EXPLAIN THE 8 FUNCTIONS…
- Maintaining Boundaries; 2. Movement; 3. Responsiveness; 4. Digestion; 5. Metabolism; 6. Excretion; 7. Reproduction; and 8. Growth
Life Function: Maintaining Boundaries
We need to maintain a separation between the internal and external environment (skin).
Life Function: Movement
Skeletal muscles create movement (locomotion).
e.g. blood, O2, CO2, urine, feces, sweat
Life Function: Responsiveness
The body needs to be able to respond to a stimulus (nervous + endocrine).
Life Function: Digestion
Taking the food we eat and breaking it down into a form that can be used by the body.
Life Function: Metabolism
The sum of all cellular activity.
Life Function: Excretion
The elimination of waste.
Life Function: Reproduction
Survival of the species. Cells divide to produce daughter cells.
Life Function: Growth
By using the food we eat, we need our cells to grow. Growth must outpace destruction to maintain life.
Definition: Homeostasis
The body’s ability to maintain a stable internal balance within certain physiological limits.
Definition: Anatomical Position
Body standing erect, limbs extended, palms of the hands forward.
A universally agreed upon position of the human body which allows directional terms to be clear and consistent.
Directional Term: Prone
Face down
Directional Term: Supine
Face up
Directional Term: Superior (cranial, caphalad or rostral)
Closer to the head or higher (head & torso only)
Directional Term: Inferior (caudal)
Closer to the feet or lower (head & torso only)
Directional Term: Ventral (anterior)
More in front.
Anterior is preferred to ventral.
Directional Term: Dorsal (posterior)
More in back.
Posterior is preferred to dorsal.
Directional Term: Medial
More toward median plane (midline, center).
Directional Term: Lateral
Further away form median plane (midline, center).
Directional Term: Intermediate
Between 2 structures.
Directional Term: Proximal
Closer to where it attaches to body (extremities or limbs only)
Directional Term: Distal
Further away form where it attaches to body (extremities or limbs only)
Directional Term: Superficial (external)
Closer to the surface of the body.
Directional Term: Deep (internal)
Further away form the surface of the body.
