The inducer binds with the repressor, forming a repressor-inducer complex. This complex prevents the repressor from binding with the operator gene of the operon. This frees the operator gene so that the RNA polymerase can move from the promoter to the structural genes.
The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle and transversus abdominis muscle, is a muscle layer of the anterior and lateral (front and side) abdominal wall which is deep to (layered below) the internal oblique muscle.he transverse abdominal, so called for the direction of its fibers, is the innermost of the flat muscles of the abdomen, being placed immediately beneath the internal oblique muscle.
Primary Muscles. The primary muscles the plank works are the erector spinae, the rectus abdomimus and the transverse abdominus. The erector spinae is a large muscle that runs up the length of the back. It surrounds your spine and allows you to straighten your back and rotate side to side.he plank is one of the simplest and most effective abdominal exercises. In its most basic form, you brace yourself at the top of a pushup while contracting your core muscles. You can do multiple variations of the plank to create more challenge and target different parts of the core.
