A fan-shaped muscle lining the iliac fossa of the pelvis that acts with the psoas major to flex the thigh at the hip joint.
Situated in the abdominal / lumbar region (right anatomical side, central plane) within the muscles.
Jump directly to connected anatomical structures to compare their locations, functions, and 3D relationships.
Muscles pull on skeletal attachments to move bones at joints and hold the skeleton in postural alignment.
Tendons, aponeuroses, and fascial sheaths transmit the contractile force of skeletal muscles onto bones and cartilage.
Contraction of the diaphragm and intercostal muscles changes intrathoracic pressure to draw air into the lungs.
