What direction do the fibres of the external oblique muscle travel in?anteriorly, inferiorly and medially
What direction do the fibres of the internal oblique muscle travel in?anteriorly, superiorly and medially
What is the origin of the external oblique muscle?Ribs 5-12
What is the insertion of the external oblique muscle?Iliac crest, pubic tubercle, linea alba
What is the innervation of the external oblique muscle?Thoracoabdominal nerve + subcostal nerve

What is the insertion of rectus abdominis?Costal cartilages of ribs 5-7, xiphoid process
What is the innervation of rectus abdominis?Thoracoabdominal nerve
What is the action of rectus abdominis?Flexion of lumbar spine
What is the origin of pyrimidalis?Pubic symphysis and pubic crest
What is the insertion of pyrimidalis?Linea alba
What is the innervation of pyrimidalis?Subcostal Nerve

What forms the posterior component of the rectus sheath between the costal margin and the ASIS?Transverse aponeurosis
What forms the anterior component of the rectus sheath below the level of the anterior superior iliac spine?Aponeurosis of all 3 muscles (external, internal, transverse)
What forms the posterior component of the rectus sheath below the level of the ASIS?Posterior component of the rectus sheath is absent here
Where and what is the arcuate ligament?Area of transition between having and not having a posterior component of rectus sheath
What is found within the rectus sheath?Rectus abdominis, Linea alba, Inferior epigastric vein and artery
Which nerves supply the anterolateral abdominal wall?Ant. rami of T7-L1
