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.
The deepest of the flat muscles, with transversely running fibres. Like the other flat muscles, it contributes aponeurotic fibres to the linea alba. Deep to this muscle is a well formed layer of fascia, called the transversalis fascia.Â© 2015 TeachMeAnatomy.com [CC-BY-NC-ND 4.0]. Fig 1.1 â Lateral view of the abdominal wall.he largest and most superficial flat muscle in the abdominal wall. Its fibres run inferomedially. As the fibres approach the mid-line, they form an aponeurosis (a broad flat tendon). In the mid-line, the aponeuroses of all the flat muscles become entwined, forming the linea alba.
