30 Cards in this Set

  • Front
  • Back
most superficial muscle of posterior thorax; very broad origin and insertion
trapezius (neck)
originates from occipital bone; ligamentum nuchae; spines of c7 and all thoracic vertabrae
trapezius (neck)
inserted into acromion and spinous process of scapula; lateral third of clavicle
trapezius (neck)
extends head; raises, rotates and retracts (adducts) scapula and stabilizes it; superior fibers elevate scapula (as in shrugging shoulders); inferior fibers deppress it
trapezius (neck)
broad flat muscle of lower back (lumbar region); extensive superficial origins
latissimus dorsi
its origin is indirect attachement to spinous process of lower 6 thoracic vertebrea, lumbar vertebrae, last 3-4 ribs, and illiac crest
latissimus dorsi
inserted in floor of interbercular groove of humerus
latissimus dorsi
prime mover of arm extension; medially rotates arm; deppresses scapula; brings arm down in power stroke, as in striking a blow
latissimus dorsi
located inferiorly to teres minor and lateral and inferior to rhomboid
teres major (shoulder)
originates posterior surface at inferior angle of scapula
teres major(shoulder)
inserted in intrabercular groove of humerus
teres major(shoulder)
extends, medially rotates, and adducts humerous; synergist of latissimus dorsi
teres major(shoulder)
located at the back and side of neck, deep tp trapezius
levator scapulae
originates in transverse processes of C1-C4 (cervical vertebrae)
levator scapulae
inserted in medial border of scapula superior to spine
levator scapulae
pulls scapula medially (retraction); stabalizes scapula; rotates glenoid cavity downward
rhomboid
elevates and adducts scapula; with fixed scapula, flexes neck to the same side
levator scapule
beneath trapezius and inferior to levator scapulae
rhomboids (minor is more superior)
originates in the spinous process C7 and T1-T5 (thoracic vertebrea)
rhomboids
inserted in medial border of scapula
rhomboids
largest and most superficial of gluteal muscles (which form buttox mass); important injection site
gluteus maximus (hip)
originates in dorsal ilium, sacrum, and coccyx
gluteus maximus (hip)
inserted in gluteal tuberosity of femur and iliotibial tract
gluteus maximus (hip)
complex powerful thigh extensor (most effective when thigh is flexed, as in climbing stairs- but not in walking); antagonist of iliopsoas; laterally rotates and abducts thigh
gluteus maximus (hip)
partially covered by gluteus maximus; superior to it; important injection site
gluteus medius (hip)
originates in upper lateral surface of ilium
gluteus medius (hip)
inserted in greater trochanter of femur
gluteus medius (hip)
abducts and medially rotates thigh; steadies pelvis during walking
gluteus medius (hip)
abducts and medially rotate thigh
gluteus medias
laterally rotates and abducts thigh
gluteus maximus
