Question | Answer |
Arrangement of Fascicles | Parallel, Convergent, Circular, Unipennate, Bipennate, Multipennate. |
Parallel Fascicles | Long axis run parallel. Ex. Rectus abdominis, Sartorius. |
Convergent Fascicles | Broad origin, converge towards insertion. Ex. Pectoralis major. |
Circular Fascicles | Concentric rings. Ex. Obicularis oris, Obicularis oculi. |
Pennate Fascicles | Short and obliquely attached. Unipennate: Extensor digitorum. Bipennate: Rectus femoris. Fibers come off both sides of the tendon. Multipennate: deltoid. |
Naming Muscles | Action: supinator. Body Region: Rectus femoris. Attachments: sternocleidomastoid. Orientation: external abdominal oblique. Shape/size: Gluteus maximus. #of Attachments: Triceps brachii |
Brachial Muscles (4) Name, Origin, Insertion | BICEPS BRACHII, Supraglenoid tubercle, coracoid pro, Radial tuberosity. BRACHIALIS, shaft -humerus, Coranoid pro. BRACHIORADIALIS, lateral supracondylar ridge, styloid pro-radius. TRICEPS BRACHII, infraglenoid tubercle & shaft of humerus, olecranon pro |
Tendon | Continuation of endomysium, perimysium, and epimysium. |
Rotator Cuff Muscles (4) Name, Origin, Insertion SITS muscles! | SUPRASPINATUS, supraspinous fossa, greater tubercle. INFRASPINATUS, infraspinous fossa, greater tubercle. TERES MINOR, lateral border of scapula, greater tubercle. SUBSCAPULARIS, subscapular fossa, lesser tubercle. |
Intertubercular Groove Muscles (3) | Pectoralis Major, Teres Major, Latissimus dorsi. "2 majors and a mus." |
Pectoralis Major O & I | O: Clavicle, sternum, ribs 2-6 I: Intertubercular groove |
Teres Major O | O: Lateral border & inferior angle of scapula I: Intertubercular groove |
Latsissimus dorsi O | O: Spinous processes of T7-T12, ribs 8-12, iliac crest, thoracolumbar fascia I: Intertubercular groove |
Quadriceps Muscles (4) | Rectus femoris, Vastus lateralis, Vastus intermedius, Vastus medialis. |
Rectus femoris O | O: Anterior inferior iliac spine I: Tibial tuberosity |
Vastus lateralis O | O: Greater trochanter & linea aspera I: Tibial tuberosity |
Vastus intermedius O | O: Shaft of femur I: Tibial tuberosity |
Vastus medialis | O: linea aspera & intertorchanteric line I: Tibial tuberosity |
Hamstring Muscles (3) Origins and Insertions | BICEPS FEMORIS, Ischial tuberosity & linea aspera, Head of fibula. SEMIMEMBRANOSUS, Ischial tuberosity, Medial condyle of tibia. SEMITENDINOSUS, Ischial tuberosity, Pes anserinus. |
Agonist | (Prime mover) Produces a particular movement. Does the majority of movement at a joint. |
Antagonist | Opposes the agonist. |
Synergist | Aids the prime mover. |
Fixator | A synergist that assists the agonist by stabilizing the joint at the origin. Ex. Elbow flextion agonist=biceps brachii. fixator=deltoid. |
Muscular Dystrophy | Inherited group of muscle disorders. Muscles enlarge, though muscle fibers atrophy. Most common and serious form is Duchenne. X-linked recessive gene. 1 in 3500 births. Mostly male. Lacks protein dystrophin. |
