Psoas major
Psoas minor will only attach to the vertebral body of which segments
T12, L1
What is the name given to ligaments that attach the vertebral body to articular process
Transforaminal ligaments
What ligaments attach the vertebral body to the transverse process
corporotransverse ligaments
Hofmann ligaments are identified in which regions along the vertebral column
Cervical - Upper thoracic region and lumbar region
Cervical - Upper thoracic Hofmann ligaments will attach to what structures together
dura mater to segments above
What is the highest level know to demonstrate hofmann ligaments
C6
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
Lumber 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 osseous conditions of lumbar vertebra facillitate a spinal tap in this region
There is NO lamina overlap (shingling), Spinous process overlap (Imbrication)
What is the name of the elevation near the origin of the lubar transverse process
Accessoty process
A styloid process occurs with what frequency and as a result of what condition
7% occurrences as a result of congenital elongation of the lumber accessory process
What muscles attach to the lumbar accessory process

intertransersarii
What muscles may attach to the transverse process of a typical lumbar vertebra
psoas major Quadratus lumborum longissimus thoracis rotator brevis rotator longus intertransversarii
What muscles will attach to lumbar superior articular process
Multifidis and intertransversarii
What ligament will attach to the lumbar superior articular process and transverse process
Mammillo-accessory ligament
What was believed to be entrapped by the mammilo-accessory ligament
