POTENTIAL PHGY 215 FINAL SHORT
EXAM 2025/2026 QUESTIONS AND
ANSWERS 100% PASS
Identify and describe the basis of muscular contraction at the level of the sarcomere, muscle
unit, and whole muscle to explain different ways skeletal muscles contract - ANS -stretching
and shortening
-actin-myosin cross bridges, sarcomere shortening
-twitch and motor unit summation
-action potentials brought down to t-tubules, SR delivers ca +2 and atp to thin and thick
filaments
Differentiate between types of skeletal muscle fibres and draw connections between their
unique features and functions within the body. - ANS Myofibrils, sarcomere
Explain the main processes involved in voluntary and involuntary motor control to determine
how damage to structures and/or pathways would affect movement - ANS -voluntary:
smooth and cardiac muscles
-involuntary: skeletal muscles
Compare and contrast the features of skeletal, smooth, and cardiac muscle to understand
important structure-function relationships - ANS -smooth muscles found in vessels, constant
contraction helps fluid move along pathways
