What is the proposed function of the cervical - upper thoracic Hofmann ligaments?
resist caudal movement of the dural sac; resist gravitational forces on the dura and cord
Lumbar Hofmann ligaments will attach what structures together?
dura mater to lower segmental levels
What is the proposed function of the lumbar Hofmann ligaments?
resist cranial movement of the dural sac during flexion
What is the proposed function of the proximal root sleve ligament?
resist displacement of the peripheral nerve system in the intervertebral foramen
What osseous conditions of lumbar vertebrae facilitate a spinal tap in this region?
overlap of the laminae, shingling, diminishes; overlap of spinous processes, imbrication, diminishes
What is the name of the elevation near the origin of the lumbar transverse process?
accessory process
A styloid process occurs with what frequency and as a result of what condition?

What was believed to be entrapped by the mammillo-accessory ligament?
the medial branch of the dorsal ramus of a lumbar spinal nerve
What muscle(s) attach to the lumbar accessory process?
longissimus thoracis and intertransversarii
What muscles may attach to the transverse process of a typical lumbar vertebra?
