Questions Fully Solved.
What 4 ways do you examine the body? - Answer Inspection, Palpation, Auscultation and
Percussion
Inspection - Answer Seeing the body
Palpation - Answer to examine by touch
Auscultation - Answer Listening with a stethoscope
Percussion - Answer taking hands and beating over certain parts of body
Medical Imaging - Answer methods of viewing the inside of the body without surgery, i.e.
radiology
Gross Anatomy - Answer Study of structures that can be seen with the naked eye
Histology - Answer the study of the microscopic structure of tissues
Histopathology - Answer microscopic examination of tissues for signs of disease
Cytology - Answer study of structure and function of cells
Ultrastructure - Answer fine detail, down to the molecular level, revealed by the electron
microscope
Subdisciplines of Physiology - Answer neurophysiology, endocrinology, pathophysiology
Neurophysiology - Answer physiology of the nervous system
,Hippocrates - Answer Father of medicine
Scientific Fact - Answer information that can be independently verified
Law of Nature - Answer a generalization about the predictable ways in which matter and
energy behave
Theory - Answer explanatory statement or set of statements derived from facts, laws and
confirmed hypotheses
Bipedalism - Answer the ability to walk upright on two legs
The Hierarchy of Complexity - Answer Organ system-organs-tissues-cells-organelles-molecules-
atoms
situs invertus - Answer heart is on the opposite side
Organization - Answer living things exhibit a higher level of organization than nonliving things
Cellular Composition - Answer living matter is always compartmentalized into one or more
cells
Metabolism - Answer internal chemical reactions; the sum of all biochemical events that occur
in the body
Responsiveness - Answer ability to sense and react to stimuli (irritability or excitability)
Movement - Answer of organism and/or of substances within the organism
Characteristics of life - Answer organization, cellular composition, metabolism, responsiveness
and movement, homeostasis, development, reproduction, evolution
, Physiological Variation - Answer Sex, age, diet, weight, physical activity, genetics and
environment
Feedback Loops - Answer biological mechanisms where homeostasis is maintained
Homeostasis in Body Temperature - Answer -If too warm, vessels dilate in the skin and
sweating begins (heat-losing mechanism)
-If too cold, vessels in the skin constrict and shivering begins (heat-gaining mechanism)
Negative Feedback - Answer a mechanism of response in which a stimulus initiates reactions
that reduce the stimulus
Receptor - Answer structure that senses change in the body
Integrating (control) Center - Answer control center that processes the sensory information,
"makes a decision," and directs the response
Effector - Answer cell or organ that carries out the final corrective action to restore
homeostasis
Positive Feedback - Answer Self-amplifying cycle where the feedback loop is repeated. Normal
way of producing rapid changes. Can sometimes be dangerous. ex. childbirth
Gradient - Answer a difference in chemical concentration, charge, temperature, or pressure
between two points. Chemicals flow down concentration gradients. Charged particles flow
down electrical gradients. Heat flows down thermal gradients.
CT Scan - Answer computed tomography scan
MRI - Answer magnetic resonance imaging
PET scan - Answer a visual display of brain activity that detects where a radioactive form of
glucose goes while the brain performs a given task
