Lumbar Hypaxial Muscles

- arise on the ventral surfaces of the

caudal thoracic and lumbar vertebrae and insert on the os

coxae and femur. They lie on one another in several layers.

m. psoas minor

Action: To steepen the pelvis by flexion

of the lumbosacral joint

m. psoas major -

Action: To draw the pelvic limb cranial

by flexion of the hip joint

m. quadratus lumborum

Action: Flexion and fixation of

the lumbar vertebral column

Muscles of the Pelvis and Thigh

Pelvic Muscles

extend between the pelvis and the thigh and include a

lateral and medial group.

Lateral pelvic muscles

are arranged in several layers and include the

tensor fascia lata, three gluteal muscles, and the piriformis.

m. tensor fasciae latae

Action: To flex the hip, abduct the limb and extend the stifle joint.

m. gluteus superficialis

- Action: Extension of the hip joint

m. gluteus medius

Action: Medial rotation of the hip and

prevention of lateral rotation during weight bearing

m. gluteus profundus

- the deepest of the gluteal muscles

m. piriformis

- lies caudal and medial to the m. gluteus medius and

is completely covered by the m. gluteus superficialis.

Medial pelvic muscles

also called the “small pelvic association,” and

include a group of short muscles that lie caudal to the m. gluteus profundus

and the hip joint.

caudal thigh muscles

m. abductor cruris caudalis

has been called m. tenuissimus in cats.
