Fundamentals of Anatomy and Physiology, 11th Edition
TEST BANK by Frederic H Martini,
Describe the following terms and concepts as used in Anatomy and Physiology?
Radioisotopes - ANSWER:Unstable isotopes that decay and give off radiation in a
process called radioactivity
Ion - ANSWER:A charged particle with unequal number of protons and electrons
Ionization - ANSWER:Transfer of electrons from one atom to another
Anion - ANSWER:Net negative charge due to gain of electrons
Cation - ANSWER:Net positive charge due to loss of electrons
Gross Anatomy - ANSWER:The study of structures able to be seen with the naked
eye
Homeostasis - ANSWER:Maintenance of dynamic equilibrium within an organism's
internal environment
Negative Feedback - ANSWER:Feedback mechanism that maintains dynamic
equilibrium, like a thermostat
Positive Feedback - ANSWER:Self-amplifying process that leads to greater change in
the same direction
Vasoconstriction - ANSWER:Constriction of blood vessels, leading to shivering
Vasodilation - ANSWER:Dilation of blood vessels, leading to sweating
Concentration Gradient - ANSWER:Flow of chemicals from an area of higher
concentration to lower concentration
Thermal Gradient - ANSWER:Flow of heat from an area of higher temperature to
lower temperature
Histology - ANSWER:Microscopic anatomy, the study of tissues
Cytology - ANSWER:The study of structure and function of individual cells
Histopathology - ANSWER:Microscopic examination of tissue for diseases
Covalent Bonds - ANSWER:Strongest type of chemical bond where atoms share
electron pairs
