aplasia A developmental failure resulting in the absence of any organ tissue.
cardiac muscle The muscle that makes up the muscular wall of the heart.

inguinal region The right and left regions of the lower section of the abdomen;also called the iliac region.
lateral Toward the side of the body, away from the midline section of the abdomen.
lumbar region The right and left regions of the middle section of the abdomen.
