![Page 2: Deep Back and Suboccipital Triangle. Objectives: 1.Describe the structure, attachments, function and support of: splenius capitus and cervicis erector.](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649d755503460f94a553e3/html5/thumbnails/2.jpg)
Objectives:1.Describe the structure, attachments, function and
support of:
• splenius capitus and cervicis• erector spinae• transversospinal group• intersegmental group
2.Describe the attachments, actions and support of the suboccipital muscles.
3.Describe the boundaries, contents and relationships of the suboccipital triangle.

Thoracolumbar Fascia
The thoracolumbar fascia:
• surrounds the deep muscles of the back
• superiorly, continuous with deep fascia of the neck
• “deep” to serratus posterior muscles
• medially, attaches to the spines of the vertebrae
• laterally, attaches to the transverse processes
• inferiorly, attaches to lower border of 12th rib and iliac crest

A 35-year-old male presents with the main complaint of lower back discomfort. Physical exam reveals that L1 – L4 are SBL and RR.
Dysfunction of what muscle is most likely responsible for this finding?
(SBL = side bend to the left…Rr = rotated to the right side)…
