Questions with Answers
Anatomy - -Study of structure
-Physiology - -Study of function
-6 levels of organization - -Atomic, cellular, tissue, organ, organ system, organism
-Tissue definition - -Groups of cells with a primary function
-Organ definition - -Groups of cells with many functions
-Organism definition - -Multiple organ systems working together to maintain the life form
-Homeostasis - -levels of organization working together to create a stable environment
-Receptor - -Senses a stimulus
-Control Center - -Received information from the receptor and processes the stimulus
-Effector - -Responds to the control center's indication
-Feedback Mechanisms - -The control of biological reactions by the end product of those
reactants (Positive and Negative)
-Negative Feedback - -Stimulus produces a response that negates the original stimulus
(Ex- Dog barks, we yell, dog stops barking)
-Positive Feedback - -Stimulus produces a response that enhances the original stimulus
(Ex- Get a cut, blood clots, blood keeps clotting until the cut is sealed)
-Anatomical Landmarks definition - -Palpable structures that are universal landmarks for
identification or areas of interest/injury
-Abdominopelvic Regions - -
-Abdominopelvic Quadrants - -
-Anatomical Directions - -directional terms used for identification purposes
-Transverse Plane - -Divides superior and inferior
-Frontal Plane - -Divides anterior and posterior
, -Saggital plane - -Divides left and right
-Body Cavities - -Chambers lined by serous membranes
-Ventral Body Cavities - -Thoracic (Holds upper cavities including L& R Pleural,
Mediastinum, and Pericardial) and Abdominopelvic (holds inferior cavities including pelvic
and abdominal)
-Visceral - -Close to
-Parietal - -Far from
-Peritoneum - -Lining of the abdominal cavity
-Pericardium - -Lining of the pericardial cavity
-Matter - -Anything that has mass and takes up space
-Mass - -The amount of matter in an object
-Weight - -A measure of the force of gravity on an object
-Elements - -The simplest chemical substance
-Atoms - -smallest unit of matter
-Protons - -Positively charged subatomic particles found in the nucleus of an atom
-Neutrons - -Uncharged subatomic particle; found in the atomic nucleus
-Electrons - -Negatively charged subatomic particles found in the electron cloud
-Mass Number - -mass of an atom equal to the number of protons + the number of
neutrons
-Atomic Mass/Weight - -Actual mass of an atom written below the element on the periodic
table
-Atomic Number - -Defines the element and describes the number of protons
-Isotopes - -The varied atomic forms of an element
-Half-Life - -Length of time required for half of the radioactive atoms in a sample to decay
-Valance Electrons - -The electrons in the outermost shell of an atom
