dorsalis scapulae
dorsal fascia, raises arm dorsally
latissimus dorsi
urostyle, straightens the back and raises the head
longissimus dorsi
anterior end of the illium, extensor of the back
iliolumbaris
periphery of the urostyle, singly turns the back and raises it
coccygeosacralis
middle of the lateral surface of the ileum,draws thigh upward and forward
gluteus
urostyle, holds urostyle in place
coccygeo-iliacus
dorsal fascia, compressor of the abdomen and respiratory muscle
external oblique
pubis, supports the abdomen and holds the sternum
rectus abdominis
transverse process, same with external oblique
transversus
rotates the femur forward
gluteus
pelvic girdle, extensor of the shank
triceps femoris
anterior surface of lateral sacrum, lateral rotation
pyriformis
dorsal side of the ischium, flexes the shank
semimebranosus
crest of the ilium above the acetabulu, adducts the thigh against the trunk, extend to the shank
biceps femoris
distal end of the femur by a flat tendin and enge of knee tendon, extends the foot and flexes the shank
gastrocnemius
knee tendon, draws shank against the thigh and extends or twist the foot
peroneus
anterior end of mandible, pushes sublingual tubercle on lower jaw
submental
dorsally on coracoid and clavicle, bulges hyoid ventally
geniohyoid
hyoid, retracts the tongue
hyoglosus
inner side of lower jaw, raises the floor of the mouth cavity
mylohyoid
episternum, draws the arm forward
sternoradialis
anterior half or rectus abdominis, adducts and flexes the arm and rotates it medially
pectoralis
clavicle, scapula and omosternum, draws arm forward
deltoid
abducts and adducts thigh, bend thigh ventrally
adductor magnus and longus
flexes the thigh and pulls thigh ventrally forward
sartorius
adducts the thigh and flexes the shank
semitendinosus
flexes the knee
gracilis minor and major
extends the shank
