Naming Muscles Direction of Fibres 1. Rectus (straight) ex: rectus abdominus 2. Transverse (across) ex: transverse abdominus 3. Oblique (diagonally) ex: obliques

Naming Muscles Location 1. Pectoralis (chest) ex: pectoralis major & minor 2. Gluteus (buttock)

Naming Muscles Location 1. Pectoralis (chest) ex: pectoralis major & minor 2. Gluteus (buttock) ex: gluteus maximus, medius & minimus 3. Brachii (arm) ex: biceps & triceps brachii 4. Supra- (above) ex: supraspinatus 5. Infra- (below) ex: infraspinatus 6. Sub- (under or beneath) ex: subscapularis 7. Lateralis (lateral) ex: vastus lateralis

Naming Muscles Number of Origins 1. Biceps (two heads) ex: biceps brachii 2. Triceps

Naming Muscles Number of Origins 1. Biceps (two heads) ex: biceps brachii 2. Triceps (three heads) ex: triceps brachii 3. Quadriceps (four heads) ex: quadriceps femoris

Naming Muscles Origin and Insertion 1. Sternocleidomastoid • origin on the sternum and clavicle,

Naming Muscles Origin and Insertion 1. Sternocleidomastoid • origin on the sternum and clavicle, insertion on the mastoid process 2. Brachioradialis • origin on the brachium or arm insertion on the radius).

Naming Muscles Action 1. Abductor moves parts of the body away from parts nearby

Naming Muscles Action 1. Abductor moves parts of the body away from parts nearby ex: abductor pollicis abductor digiti minimi • 2. Adductor 3. Flexor • moves parts of the body toward parts nearby ex: adductor longus, brevis & magnus • causes a joint to bend, decreasing joint angle ex: flexor carpi radialis flexor hallicus longus 4. Extensor • causes a joint to straighten ex: extensor carpi ulnaris extensor indicis 5. Levator • lifts a structure ex: lavator scapulae

Muscle Groupings Rotator Cuff Four muscles that extend from the scapula to the humerus

Muscle Groupings Rotator Cuff Four muscles that extend from the scapula to the humerus wrapping around the shoulder joint, holding it in place S. I. T. S. 1. 2. 3. 4. Supraspinatus Infraspinatus Teres Minor Subscapularis

Muscle Groupings Gluteal Muscles • Originate on the pelvic girdle and insert on the femur 1. Gluteus Maximus 2. Gluteus Medius 3. Gluteus Minimus

Muscle Groupings Quadriceps Femoris • The large muscle group, consisting of four separate muscles,

Muscle Groupings Quadriceps Femoris • The large muscle group, consisting of four separate muscles, that cover the front and the sides of the thigh • All quadriceps muscles join distally via the patellar tendon, but have their own origins • They are extensors of the knee 1. Rectus Femoris 2. Vastus Lateralis 3. Vastus Intermedius 4. Vastus Medialis

Muscle Groupings Hamstring Muscles • Originate on the pelvis & insert on the tibia

Muscle Groupings Hamstring Muscles • Originate on the pelvis & insert on the tibia or fibula • They are flexors of the knee 1. Biceps femoris 2. Semimembranosus 3. Semitendanosus
