Question | Answer |
closes eyelid, aids in flow of tears across eye | orbicularis oculi (2) |
closes lips, protudes lips as in kissing, speech | orbicularis oris (3) |
compresses cheek against teeth, directs food between molars, retracts teeth from cheek when mouth is closing to prevent biting cheek, expels air and fluid | buccinator (4) |
elevates corner of mouth (smile), exposes upper teeth | zygomaticus |
opens jaw, depresses lower lip | platysma |
closes mandible, elevation of mandible | masseter |
closes mandible | temporalis |
tilts head forward | sternocleidomastoid |
elevates scapula, flexes neck laterally, retracts scapula and braces shoulder, rotates scapula | levator scapulae |
extends and laterally flexes head, stabilizes scapula and shoulder, elevates and depresses shoulder, rotates and retracts scapula, abducts head, rotates and adducts scapula | trapezius |
medially rotates arm, abducts arm, extend and laterally rotate arm | deltoid |
flexes, adducts, medially rotates humerus and arm, aids in deep inspiration | pectoralis major |
rotates scapula, depresses shoulder, raises ribs 3-5 | pectoralis minor |
adducts and medially rotates humerus; extends the shoulder, produces backward swing of arm, pulls body forward and upward (climbing), aids in deep inspiration, sudden expiration, and prolonged forceful expiration (singing) | latissimus dorsi |
w/deltoid abducts arm, helps stabilize shoulder | supraspinatus |
laterally rotates humerus/arm, stabilizes shoulder, abducts arm | infraspinatus |
rotates humerus/arm medially, stabilizes shoulder, abducts arm | subscapularis |
rotates humerus/arm laterally, stabilizes shoulder, adducts arm | teres minor |
extends and medially rotates humerus/arm (arm swinging), adducts arm | teres major |
elbow flexion, shoulder flexion, flexes arm | biceps brachii |
extends elbow/arm, adducts humerus/arm, extends forearm | triceps brachii |
flexes and medially rotates arm, adducts arm | coracobrachialis |
elbow flexion | brachialis |
flexes elbow | brachioradialis |
flexes thigh, flexes trunk at hip, balances trunk during sitting | iliopsoas |
aids in knee and hip flexion; abducts and laterally rotates thigh | sartorius |
flexes and medially rotates tibia at knee, adducts thigh, flexes thigh | gracilis |
flexes and adducts thigh | pectineus |
adducts, flexes, laterally rotates thigh | adductor brevis |
adducts, flexes, and medially rotates thigh, flexes thigh at hip | adductor longus |
adducts, and medially rotates thigh, extends thigh at hip | adductor magnus |
extends knee, flexes thigh at hip, flexes trunk on hip if thigh is fixed | rectus femoris |
extends knee | vastus lateralis, vastus intermedius, vastus medialis |
extends knee, laterally rotates tibia, abducts and medially rotates thigh | tensor fasciae latae |
extends thigh at hip, abducts thigh, elevates trunk after stooping, prevents trunk from pitching forward during walking and running | gluteus maximus |
abducts and medially rotates thigh, shifts weight of feet when walking | gluteus medius |
abducts and medially rotates thigh, shifts weight of feet when walking | gluteus minimus |
flexes knee, extends hip/thigh, elevates trunk after stooping, laterally rotates tibia on femur when knee is flexed, laterally rotates femur when hip is extended, counteracts forward bending at hips | biceps femoris |
flexes knee; extends thigh, medially rotates tibia on femur, medially rotates femur, counteracts forward bending at hips | semitendinosus or semimembranosus |
plantar flexes foot, flexes knee | gastrocnemius |
plantar flexes foot, steadies leg on ankle during standing | soleus |
everts foot, plantar flexes foot | fibularis longus |
stabilizes vertebral column during heavy lifting, maintains posture, compresses abdominal organs, laterally rotates trunk | external abdominal oblique or internal abdominal oblique |
compresses abdominal contents, laterally rotates trunk | transverse abdominis |
flexes lumbar region of vertebral column, forward bending at waist, compresses abdominal wall | rectus abdominis |
protracts scapula, rotates scapula to elevate shoulder, abducts scapula | serratus anterior |
elevates and protracts ribs, braking action during expiration | external intercostals |
depress and retract ribs and expels air, used in forceful expiration | internal intercostals |
inspiration and expiration, contracts in preparation for sneezing, coughing, etc. | diaphragm |
extension and lateral flexion of vertebral column, extends and rotates vertebral column and head | erector spinae |
retracts scapula and braces shoulder, fixes scapula during arm movements, adducts scapula | rhomboideus major or minor |
dorsiflexes and inverts foot, resists backward tipping of body | tibialis anterior |
aids in respiration, extends and abducts vertebral column | quadratus lumborum |
extends and rotates head | splenius |
extends and rotates head, extends adn rotates vertebral column | semispinalis |
