Review of the Arm Muscle Model

Presentation transcript:

Biceps brachii Flex the elbow

Triceps brachii Extends arm

Brachioradialis Flexes elbow Supinates and pronates!

Coracobrachialis Adduct

Brachialis Flexes arm

Pectoralis major

Pronator Teres

Palmaris longus Wrist flexor Sometimes absent

Supinator

Levator scapulae What do you think it is responsible for?

Deltoid Abducts the arm

Rhomboid major Retracts scapula toward vertebral column

Rhomboid Minor Retracts scapula

Latissimus dorsi

Trapezius Moves the shoulder -Retracts -Depresses

Teres major and minor Adductor of humerus Medial rotates humerus

Serratus anterior “Boxer’s muscle” Protraction of scapula

Supraspinatus Abducts arm

Infraspinatus Rotates shoulder Abducts arm

Intercostals Help facilitate breathing
