BSC 2085 COMPREHENSIVE 2026 EXAM QUESTIONS
AND ANSWERS GRADED A+
✔✔Negative feedback - ✔✔allows for Dynamic Equilibrium within a limited range
around a Set Point
-body senses a change and "negates" or reverses it
-Loss of homeostatic control and causes illness or death
✔✔Homeostasis and Negative feedback involve three things, what are they? - ✔✔-
Receptor
-Integrating (control) center
-Effector
✔✔Receptor - ✔✔structure that senses change in the body (e.g. stretch receptors
above heart monitor blood pressure)
✔✔Integrating (control) center - ✔✔Conrtol center that processes the sensory
information, "makes a decision" and directs the response
(e.g. cardiac center of the brain)
✔✔Effector - ✔✔cell or organ that carries out the final corrective action to restore
homeostasis (e.g. the heart)
✔✔Positive feedback - ✔✔Rapid change
Self -Amplyfying cycle
-leads to greater change in teh same direction
-feedback loop is repeated- change produces more change
Can be Dangerous
EX: childbirth, runaway fever, blood clotting, protein digestions
✔✔Gradient - ✔✔difference in chemical concentration, charge, temperatuer, or
pressure between two points
✔✔T or F
Matter and Energy flow up gradients - ✔✔False
✔✔Chemicals flow ___________ the gradients - ✔✔down
✔✔Charged particles flow down __________________ gradients - ✔✔electrical
, ✔✔Heat flows down ___________________ gradients - ✔✔thermal
✔✔About _____% of our current medical terms come from 1,200 Greek and Latin roots
reflecting ancient past - ✔✔90
✔✔What is an eponym? - ✔✔when structures are named after people
✔✔Terminologia Anatomica (TA) - ✔✔-Provided Latin names and English equivalents
-adopted by anatomists in over 50 countries
✔✔Acronym - ✔✔PET <-
✔✔Scientific terms - ✔✔-root:core meaning
-Combining Vowels: join roots in word
-Prefix and Suffix: may modify meaning of a root word
✔✔plural fform of Cortex - ✔✔Cortices
✔✔Plural form of Corpus - ✔✔Corpora
✔✔Brachium - ✔✔arm
✔✔Brachii - ✔✔of the arm
✔✔ Anatomy - ✔✔study of structure
✔✔Physiology - ✔✔study of function
✔✔What are the several ways to examine the anatomy of a human body - ✔✔-
inspection
-palpation
-auscultation
-percussion
-dissection
✔✔Inspection - ✔✔looking at the body appearance, making diagnosis based on surface
appearance, involves touch and listening to body
✔✔Auscultation - ✔✔is listening to the natural sounds made by the body
-like the heart and lungs
✔✔Percussion - ✔✔examiner taps the body, feels for abnormal resistance, and listens
to the emitted sound for abnormalities such as pockets of fluids or air
