Attachment
This specific anatomical location is on the scapula where the subscapularis originates.
What is the subscapular fossa?
This is primarily responsible for this motion this rotator cuff muscles rotates the arm away from the body's midline.
What is external rotation?
These two lateral lumbricals two and three are innervated by this specific nerve.
What is the Median nerve?
Positioned above Latissimus Dorsi this muscle is often called lat's little helper located on the back of the shoulder joint.
What is the Teres Major?
This bony structure is on the lateral third of the clavicle serving as the origin for the anterior deltoid.
What is the clavicle?
With the superior nuchal line this bony landmark is at the back of the skull its main origin point is for the upper trapezius.
What is the external occipital protuberance?
The lateral and medial heads only act on the elbow the specific head of the triceps acts to extend and adduct the shoulder.
What is the long head?
This Pectoral nerve primarily supplies the clavicular head of the Pectoralis Major.
What is the Lateral pectoral nerve?
This muscle flexes the fifth digit, located lateral to the abductor digiti minimi and medial of the opponens digiti minimi.
What is the Flexor digiti minimi brevis manus?
A large thick connective tissue layer in the lower back acts as the major attachment point for Latissimus Dorsi.
What is the Thoracolumbar fascia?
This specific distal attachment site is on the digits for the extensor digitorum tendons.
What are the bases of the middle and distal phalanges?
When doing push ups the triceps acts as this type of muscle providing the main force for extending the elbow.
What is the antagonist/ prime mover?
The Palmaris longus receives spinal segment innervation from C6 to the thoracic level.
What is T1?
Levator scapulae is located deep into the large superficial muscle of the upper back.
What is the Trapezius?
Together two heads of Biceps Brachii originate on this bone.
What is the Scapula?
other than biceps brachii the brachialis does not attach to this bone located in the forearm becoming a pure elbow flexor.
What is the radius?
This muscle is along with the extensor carpi ulnaris working together to achieve this specific motion towards the pinky side.
What is ulnar deviation?
This is often considered a weak flexor/adductor the primary function of this slender muscle to stabilize this joint.
What is the Glenohumeral joint/ shoulder joint?
Supraspinatus tendon inserts onto specific superior bony landmark on the head of the humerus.
What is the Greater Tubercle/ facet?
Brachialis originates from this specific distal portion of the anterior humerus.
What is the distal half?
The rhomboid major contracts it performs this specific movement on the scapula opposite from upper rotation.
What is downward rotation?
These fibers of the deltoid act to horizontally abduct the shoulder.
What are the posterior fibers?
The ulnar nerve palsy causes weakness in these muscles that are responsible for Dorsal abduction.
What are the Dorsal interossei?
The deep ulnar head of pronator teres arises from this bony structure.
Rhomboid Major originates on the vertebrae, rhomboid Minor originates on the vertebrae and this ligament.
What is the Nuchal ligament?
