QUESTIONS AND CORRECT DETAILED ANSWERS
Three types of muscle
Ans: skeletal
cardiac
smooth
Quiz basic function of muscle
Ans: generate tension
Quiz functions of skeletal muscle
Ans: locomotion
facial expression
posture and body position
regulation of body temperature
Quiz voluntary contraction
Ans: requires nervous system input
some skeletal muscles are automatic, but we have the ability to change their activity
(ex: diaphragm)
Quiz muscles pull or push? how do you predict the action of a muscle?
Ans: pull
predict the action of a muscle based on location
Quiz origin
,Ans: the place where the muscle starts on a bone - stays stationary
Quiz insertion
Ans: the place where the muscle ends on a bone - moves toward the origin
Quiz standard anatomical position movement
Ans: everything is extended except feet
Quiz how to name a movement
Ans: action + name of segment that moves
ex: flexion of the forearm
Quiz types of body movements
Ans: flexion/extension
abduction/adduction
Quiz 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)
Quiz flexion/extension examples
Ans: elbow joint
knee joint
hip joint
shoulder joint
Quiz abduction/adduction
Ans: movement away or toward the longitudinal axis (or midline)
typically occur along a frontal plane in reference to the midline of the body
Quiz reverse muscle action (RMA)
Ans: when the insertion is anchored, the origin moves towards the insertion
ex: pull-ups
Quiz classifying a muscles based on action
, Ans: agonist
antagonist
synergist (includes fixator)
Quiz agonist
Ans: muscle primarily responsible for the movement (aka prime mover)
Quiz antagonist
Ans: muscle which opposes the action of the agonist
Quiz synergist
Ans: assists the agonist in making the action more efficient
Quiz fixator
Ans: special synergists which help to prevent movement at the muscle origin
Quiz classification of muscles based on action example: abduction of the arm
Ans: agonist: deltoid
antagonist: latissimus dorsi
synergist: supraspinatus
fixator: trapezius
Quiz leverage
Ans: lever = rigid bar = bone
fulcrum = fixed point around which the rigid bar (bone) moves = joint
Quiz how do muscles apply to leverage?
Ans: muscles act to facilitate movement at a fulcrum by exerting force on the lever
Quiz example of lever systems
Ans: first class levers
second class levers
third class levers
Quiz first class levers
Ans: not common
Quiz second class levers
Ans: not common
