MYOFASCIAL CONNECTIONS

Splenius capitis and cervicis

Sternocleidomastoid (sternal head)

Scalene muscles

Ribs

Intercostals Stain from bile in gall bladder

Figure 2: Lateral Line In this photograph, we see the lateral line - starting with the two peroneals (now called fibularii) at the bottom, connected fascially over the fibular head to the iliotibial tract. It was no surprise to connect this into the gluteals and tensor fasciae latae, but it was a complete surprise how easy it was to connect these gluteal fasciae with all the abdominal layers, including, as you see here, the external and internal obliques. The ribs were clipped to continue the line up the side via the external and internal intercostals.

At the top of the ribs, you see the small triangle of the scalenes, not techni- cally part of this line, but included nevertheless because of their clear fascial continuity. At the top of the picture, you see the chevron combining the splenii in the back with the sternal head of the sternocleidomastoid (SCM) in front. This part is separate in this picture only because these are both muscles that originate on the sagittal midline, and the rest of the Lateral line is more to the side.

Figure 3: Lateral Line on skeleton Here is this dissection laid out on a classroom skeleton, arranged as if walking. You can see the role these linked muscles and fascia would play in stabilis- ing the body in regular or athletic activity.
