Anterior Abdominal Wall: Structure, muscles and surface anatomy

Anterior Abdominal Wall
Structure, muscles and surface anatomy
Curricular Objectives
By the end of this session students are expected to:
Practical
1. Recall the hip bone and label its main landmarks with emphasis on internal surface
2. Locate the main surface markings of the anterior abdominal wall
3. Discriminate between and trace the extensions of the two layers of superficial fascia
4. Mark the inguinal ligament and palpate its attachment points
5. Recognize the muscles of anterior abdominal wall and the related structures
6. Identify the anterior and posterior layers of the rectus sheath and its extensions
7. Divide the anterior abdominal wall into nine regions using imaginary lines
8. Distinguish the major dermatomes of the anterior abdominal wall
Theory
1. Define the abdomen and outline its boundaries and content
2. Relate the abdominal cavity to the chest wall
3. List the layers making the anterior abdominal wall
4. State the direction of cleavage lines of abdominal skin
