Module 4 Flashcards
(16 cards)
shoulder muscles anterior
pectoralis minor and serratus anterior attach to axial skeleton via the rib cage to the pectoral girdle
shoulder muscles posterior
trapezius attaches the axial skeleton to the pectoral girdle
muscles that move the humerus
pectoralis major flexes the humerus (anterior)
latissimus dorsi extends the humerus (posterior)
deltoid muslce
moves humerus and stabilizes the glenohumeral joint
muscle abducts the arm
rotator cuff muscles
stabilize the glenohumeral joint
- subscapularis (anterior)
- supraspinatus (posterior)
- teres minor (posterior)
- infraspinatus (posterior
muscle that move the forearm
biceps brachii flexes the forearm (anterior)
triceps brachii extend the forearm (posterior)
muscle that move the wrist - anterior
flexor carpi radialis and flexor carpi ulnaris muscles flex the wrist, common origin on the medial epicondlye of humerus
muscle that move the wrist - posterior
extensor carpi radialis longus and brevis and the extensor carpi ulnaris muscles extend the wrist, common origin lateral epicondyle
palmaris longus muscle
can occur in both, one or neither wrists
muscle is superficial and inserts into connective tissues under the skin at the wrist
relates to wrist flexibility, not significant role
muscles that move the thigh
iliopsoas flexes the thigh (anterior)
gluteus maximus, gluteus medius, gluteus minimus extend the thigh
muscles the move the leg - anterior
sartorius flexes knee and hip
quadriceps solely act on knee
- has quadriceps femoris which come together to form quadriceps tendon which insert on patella
muscles the move the leg - medial
adductors move the thigh medially
minor involvement in movement of leg
muscles the move the leg - posterior
hamstring helps extend the hip and flex the knee
muscles that move the food/ankle - anterior
tibialis anterior muscle extends food (dorsiflexion
muscles that move the food/ankle - lateral
peroneus (fibularis) longus muscles evert the food
muscles that move the food/ankle - posterior
