Action

Nerve Supply

Anterior surface of scapula

Greater tubercle of humerus

Abducts the arm

Suprascapular nerve

SUPRASPINATUS FACTS

-The supraspinatus is the muscle that runs along the top of the shoulder.

-The distal supraspinatus tendon connects the supraspinatus to the upperarm bone, or humerus, and forms part of the rotator cuff, a group ofmuscles and tendons that support the shoulder.

-The other three muscles whose connections to the arm constitutethe rotator cuff are the subscapularis, which controls internal rotation; theteres minor, which controls external rotation; and the infraspinatus, whichassists the arm in elevating during external rotation.

-Supraspinatus muscle stabilizes the head of the arm bone in the shoulder

joint preventing it from slipping upwards during shoulder movements.

TRICEPS BRACHII

Origin

Insertion

Action

Nerve Supply

Tubercle below glenoid cavity and lateral an medial surfaces of humerus

Olecranon process of ulna

Extends elbow

Radial nerve

TRICEPS FACTS-They are named as triceps group of muscles, because it is not a single muscle.

-These muscles make up over two thirds of your upper arm and work with the biceps muscles.

-Triceps means three heads and that each of these heads (long, lateral and medial) performs a different function

-

-Anything that requires you to use straight arms generally means you are using your triceps.

-The most common triceps injury is a pull or rupture, this can occur during overexertion in sports or weight lifting.

DELTOID

Origin

Insertion

Action

Nerve Supply

Acromion Process, spine of the scapula, the clavicle

Deltoid tuberosity of humerus

Abducts, extends, and flexes arm

Axillary Nerve

DELTOID

DELTOID FACTS-The deltoid is broken up into three parts the front deltoid,the side deltoid, and the posterior

-Deltoids are one of the hardest muscles to develop whileworking out.

-Constantly being involved in upper body movement thedeltoid hardly gets and rest.

-The name deltoid was originally called the Deltoideus. Thisname came about by the shape of the Greek letter Deltawhich is a triangle.
