BIO 201 TEST 1 (CHAPTERS 1-4) LATEST
2025 100% COMPLETE FULL LENGTH
TEST WITH ACCURATE ANSWERS
1. Anatomy ANS >>> studies structure of body parts and how they relate to one
another
2. Gross Anatomy ANS >>> study of large structures
3. surface anatomy ANS >>> studies structures as they relate to the surface
4. cytology ANS >>> study of cells
5. histology ANS >>> study of tissues
6. embryology ANS >>> studies developmental changes that occur before birth
7. chemical level ANS >>> atoms form to combine molecules
8. tissues ANS >>> groups of similar cells that have a common function
9. cellular level ANS >>> cells are made up of molecules
10. organ level ANS >>> organs are made up of different types of tissues
11. homeostasis ANS >>> point of dynamic (changing) equilibrium; body's ability to

, maintain a relatively stable internal environment despite ever changing conditions
12. set point ANS >>> level/range of "normal" for whatever variable is being
considered ex ANS >>> blood glucose levels
13. receptor ANS >>> sensor that monitors environment and responds to changes
by send- ing information to the control center
14. control center ANS >>> determines set point; analyzes input and determines
appropri- ate response
15. effector ANS >>> provides means for control center's response to the stimulus
16. What is the correct order of the components of the loops for homeosta-
sis? ANS >>> stimulus, receptor, afferent pathway, control center, efferent pathway,
effector, response
17. Negative feedback ANS >>> 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 ANS >>> 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
18. Positive feedback ANS >>> happens in infrequent events that don't need
continual adjustment
ex ANS >>> giving birth-oxytocin is released which causes contractions to intensify,
causing more oxytocin to be released, causing baby to eventually be expelled.
Once baby is born, the stimulus for oxytocin to be released is shut off
19. neural (nervous system control) ANS >>> quick, short lived, electrical
signals ex ANS >>> allows you to get out of the way of danger quickly
20. hormonal (endocrine control) ANS >>> chemicals sent out in blood stream;
slower process that takes multiple steps; effects are more widespread and longer
lasting
