PSIO 201 EXAM 3 STUDY LATEST EXAM
2025-2026 WITH ACTUAL QUESTIONS AND
CORRECT VERIFIED ANSWERS
three types of muscle
Ans: skeletal
cardiac
smooth
Q: basic function of muscle
Ans: generate tension
Q: functions of skeletal muscle
Ans: locomotion
facial expression
posture and body position
regulation of body temperature
,Q: voluntary contraction
Ans: requires nervous system input
some skeletal muscles are automatic, but we have the ability to
change their activity (ex: diaphragm)
Q: muscles pull or push? how do you predict the action
of a muscle?
Ans: pull
predict the action of a muscle based on location
Q: origin
Ans: the place where the muscle starts on a bone - stays
stationary
Q: insertion
,Ans: the place where the muscle ends on a bone - moves
toward the origin
Q: standard anatomical position movement
Ans: everything is extended except feet
Q: how to name a movement
Ans: action + name of segment that moves
ex: flexion of the forearm
Q: types of body movements
Ans: flexion/extension
abduction/adduction
Q: flexion/extension
, Ans: movement to reduce (flexion) or increase (extension) the
angle between articulating bones at a joint
typically occur along a sagittal plane (anterior/posterior)
Q: flexion/extension examples
Ans: elbow joint
knee joint
hip joint
shoulder joint
Q: abduction/adduction
