True

Medial epicondylitis is also known as golfer's elbow.

True

Of all the movements possible in the joints of the body, flexion/extension is the most commonly occurring.

True

One of the functions of the supraspinatus muscle is to stabilize the humeral head in the glenoid fossa.

True

Positioning the forearm in pronation reduces the effectiveness of the bicep brachialis in flexing the elbow.

True

Skeletal muscles are responsible for movement of he body as a whole and movement with each of the joints of the body.

True

Some circumstances exist where movement is improved is improved when the body tends to be unbalanced.

True

Statics is he study of systems that are in constant state of motion.

True

The actions of serratus anterior include abduction and upward rotation.

True

The coracoclavicular ligament is particularly important in providing stability to the acromioclacicular joint

True

The insertion of he pectoralis major muscle is the flat tendon 2-3 inches wide to the outer lip o the intertubercular groove of the humerus.

True

The insertion of the triceps brachii muscle is the olecranon process of the ulna.

True

The medial border of the scapula above the scapular spine is the insertion point of the levator scapulae

True

The most palpable shoulder girdle muscle is the trapezius.

True

The origin of the subclavious is the superior aspect of the first rib at is junction with its costal cartilage.

True

The radial collateral ligament provides lateral stability to the elbow and is a rarely injured

True

The rotator cuff muscle group includes the subscapularis, supraspinatus, infraspinatus, and teres minor muscles

True

The serratus anterior performs abduction in the transverse plane.

True

The term "intrinsic" usually pertains to muscles within or belonging solely to the body part upon which they act.

True

The trapezius can perform adduction in the transverse plane when activated.

True

There are two major types of fiber arrangements. which are parallel and pennate.

True

When attempting extreme external rotation the total shoulder range of motion is enhanced by scapula adduction.

True

When performing a pushup the bicep brachii is considered to e an antagonist muscle.

True

While in the anatomical position the radius is medial with respect to the ulna.

False

The pectoralis minor can perform adduction, downward rotation, or depression when activated.

False

The resistance arm is the distance between the axis and the point of lever application.

False

The shape of bones does not limit movement.

False

The stability of the glenohumeral joint is enhanced by its significant mobility.

False

The synergist muscle of an activity is considered to be the primary mover.

False

The term "extensibility" refers to the ability of a muscle to return to its original length following stretching.

False

There are approximately 522 muscles in the human body.

False

Velocity is how fast an object is moving, or the distance an object travels I a specific amount of time.

False

Aging induces a progressive increase of collagen in bone that results in an increase in brittleness.

False

Assuming that the bat speed and pitched ball velocity were the same, the ball hit with the middle of the bat would travel further than the ball hit with the larger end of the bat.

False

Eccentric muscle "actions" result from isometric muscle contractions.

False

Fusiform muscle fiber arrangement results in a circular pattern.

False

Isokinetic muscle contraction involve a dynamic movement where in he speed of movement is a variable.

False

Movement at the elbow by the forearm away from the shoulder is accurately described by the term " flexion".

False

Osteoclasts are specialized cells that form and resorb new bone.

False

Posterior dislocations occur frequently at the glenohumeral joint.

False

Supination refers to internal rotary movements of the radius on the ulna.

False

The coracobrachialis muscle inserts on the coracoid process.

False

The elbow joint is a hinge-type joint that allows for internal and external rotation.

False

The insertion of the deltoid muscle is the humeral tuberosity on the lateral humerus.

False

The insertion of the pectoralis minor is the coranoid process of the scapula

False
