Muscle Action 1
This muscle attaches at superior angle of the scapula and performs scapular elevation only
What is levator scapula?
The axis that pairs with the frontal plane
What is sagittal axis?
This type of contraction occurs when decelerating or lowering a weight
What is an eccentric contraction?
This muscle's main action is extension of the 5th digit
What is extensor digiti minimi?
This joint performs flexion/extension, radial/ulnar deviation
This is the first muscle in the rotator cuff "SITS" acronym
What is supraspinatus?
The plane and axis corresponding with opening a doorknob
What is transverse plane and vertical axis?
Located in the muscle belly, this structure senses the amount a muscle is stretching
What is muscle spindle?
This rotator cuff muscle performs internal rotation
What is subscapularis?
What type of joint is the CMC joint of the thumb?
What is a saddle joint?
Actions include forearm pronation, forearm supination, elbow flexion
What is brachioradialis?
The plane associated with the action of the levator scapula
What is the frontal plane?
The number of degrees of freedom found at the glen-numeral joint
What is 3?
Common action among serratus anterior, lower trapezius, and upper trapezius
What is scapular upward rotation?
This form of scapular tilt occurs during shoulder flexion
What is posterior tilt?
Action that is common to latissimus dorsi, teres major, subscapularis, and pectoralis major
What is internal rotation?
The most functional plane of the shoulder/shoulder girdle
You step on a nail so your body reflexively flexes your hip to remove your foot from the sharp object. This nerve sensed the danger and sent information to your brain
What is afferent nerve?
This scapular movement is associated with the action of the subscapularis
What is protraction?
What is the carrying angle?
The muscle of the shoulder girdle that performs elevation, upward rotation, and retraction
What is middle trapezius?
The plane and axis of the shoulder associated with the "pressing up" phase of a bench press
What is sagittal plane and frontal axis
Ability of a muscle to be passively stretched beyond its normal resting length
What is extensibility?
This muscle would be considered the antagonist to the pronator teres
What is the supinator?
This carpal bone is the most proximal, lateral of all carpal bones
What is the scaphoid?
