BIO 201 Test 1 (chapters 1-4) UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Anatomy - CORRECT ANSWER - studies structure of body parts and how they relate to
one another
Gross Anatomy - CORRECT ANSWER - study of large structures
surface anatomy - CORRECT ANSWER - studies structures as they relate to the surface
cytology - CORRECT ANSWER - study of cells
histology - CORRECT ANSWER - study of tissues
embryology - CORRECT ANSWER - studies developmental changes that occur before
birth
chemical level - CORRECT ANSWER - atoms form to combine molecules
tissues - CORRECT ANSWER - groups of similar cells that have a common function
cellular level - CORRECT ANSWER - cells are made up of molecules
organ level - CORRECT ANSWER - organs are made up of different types of tissues
homeostasis - CORRECT ANSWER - point of dynamic (changing) equilibrium; body's
ability to maintain a relatively stable internal environment despite ever changing conditions
, set point - CORRECT ANSWER - level/range of "normal" for whatever variable is being
considered
ex: blood glucose levels
receptor - CORRECT ANSWER - sensor that monitors environment and responds to
changes by sending information to the control center
control center - CORRECT ANSWER - determines set point; analyzes input and
determines appropriate response
effector - CORRECT ANSWER - provides means for control center's response to the
stimulus
What is the correct order of the components of the loops for homeostasis? - CORRECT
ANSWER - stimulus, receptor, afferent pathway, control center, efferent pathway,
effector, response
Negative feedback - CORRECT ANSWER - once stimulus occurs, and the control center
and effector return the body to the normal position, stimuli stop as to not over-fix the problem
ex: blood glucose-once glucose levels return to normal, the stimulus for either raising blood
glucose or lowering it ends
Negative feedback is the most common occurrance of homeostatic balancing
Positive feedback - CORRECT ANSWER - happens in infrequent events that don't need
continual adjustment
