Abdomen, Breath, and Chest

Abdomen, Breath, and Chest Dissection

In the third dissection course our focus will be on the region between the pelvis and the neck. We will take you from the internal and external oblique muscles up through the three layers of the intercostals. We will explore how this is arguably the same muscle, and it’s function in breathing will be discussed. By exploring the intricate weave of the abdominal muscles we can see how the spine can act like a spinal engine to drive efficient gait.

The semilunar line, a bilateral vertical curved line in the anterior abdominal wall where the layers of the rectus sheath fuse lateral to the rectus abdominis muscle and medial to the oblique muscles will be dissected out.

Posteriorly the lateral raphe, a ridge along the lateral margin of the erector spinae muscles formed by the aponeurosis of the latissimus dorsi, internal oblique, and transversus abdominis muscles and the layers of the thoracolumbar fascia will be shown as well.

To close of the dissection we will explore the connections between the psoas and the diaphragm, and the function of the diaphragm in breathing.
