The point of origin of the Muscle of Infraspinatus is the greater tubercle of the humerus.
What are the actions of Biceps brachii? Check all that apply.
Flexes elbow (forearm)
Medial rotation of humerus
Supination of forearm (radius/ulna) and glenohumeral joint
Abducts shoulder (humerus)
Name the point of insertion for the muscle Teres Minor.
Infraspinatous fossa of scapula
Greater tubercle of Humerus
Lesser tubercle of Humerus
Identify the point of origin and insertion for the Deltoid muscle.
O: Lesser tubercle of humerus
O: Clavicle: acromion process and spine of scapula
I: Clavicle; acromion process and spine of scapula
I: Deltoid tuberosity of Humerus
The primary action of the muscle is to flex the elbow.
The action of the Deltoid muscle is to rotate
adduct( rotate, abduct, supination, adduct ) the humerus; posterior
superifical( posterior, anterior, medial, superifical ) deltoid-extension of shoulder; inferior
adduction( inferior, lateral, anterior, adduction ) deltoid flexes shoulder.
The origin of Triceps brachii are long head from scapula, and medial heads from the humerus
Label the image of the scapula (anterior and posterior views) below. Determine where the the four muscles of the rotator cuff are located.
The point of insertion for the Flexor Carpi Ulnaris is the base of the 5th metacarpal.
What is the action of the Flexor Carpi Radials?
flexes and adducts wrist
flexes and abducts wrist

The is a ball-socket joint.
What muscles make up the forearm (antebrachium)? Check all that apply.
Flexor Carpi ulnaris
Flexor Carpi radialis
Extensor carpi ulnaris
Extensor carpi radialis longus & brevis
The point of insertion for the Extensor carpi ulnas is the epicondyle of the humerus, border of ulna.
What is the action of the Brachioradialis muscle?
acts with Flexor carpi ulnaris to adduct wrist
The point of insertion of the Flexor carpi radialis is the base of the 2nd and 5th metacarpals.
The point of origin of the Flexor carpi radials is the of humerus. The insertion point is the based of the metacarpals.
Flexor carpi ulnaris acts with to adduct wrist.
Extensor carpi radialis longus and brevis act with Flexor carpi radials to the wrist.
Please identity the point of origin of Extensor carpi radialis longus and brevis below.
base of 2nd metacarpal
base of 3rd metacarpal
medial epicondyle of humerus
lateral epicondyle of humerus
The point of insertion for Extensor carpi radialis longus
Extensor carpi radialis brevis( Extensor carpi radialis longus, Extensor carpi radialis brevis ) is the base of the 2nd metacarpal. The point of insertion for Extensor carpi radialis longus
Extensor carpi radialis brevis( Extensor carpi radialis longus, Extensor carpi radialis brevis ) is the base of the 3rd metacarpal.
Determine the points of origin and insertion for the muscle Brachioradialis.
