Term
Negative Feedback System
Definition
Produces a response that reverses or counteracts the original stimulus (frequent monitoring-body gets hot, cools down)
Term
Positive Feedback System
Definition
Produces a response that enhances or intensifies the original stimulus (ovulation, blood coagulation)
Term
Disorder
Definition
Any abnormality of a structure or function
Term
Disease
Definition
A specific illness characterized by certain signs or symptoms
Term

Definition
Science that deals with the why, when, and where diseases occur and how they are transmitted
Term
Diagnosis
Definition
The science or skill of distinguishing between different disorders or diseases
Term
Symptoms
Definition
Subjective changes that are not apparent to the observer (headache)
Term
Signs
Definition
Objective changes in a patient that can be observed and measured (fever)
Term
Anatomical Position
Definition
Standard position of the body that allows consistent anatomical references for the observer- patient stands erect with feet flat on the floor and directed forward and the arms are placed at the sides with the palms turned forward
