reniform or kidney shaped
accounts for direction of the lumbar curve
the vertebral body and intervertebral disc = greater anterior height than posterior height

4
muscles attached to the first lumbar vertebral body
psoas maj.
psoas min.

psoas minor will ONLY attach to the vertebral body of which segments
T12, L1
name given to ligaments that attach the vertebral body to articular process
transforaminal ligaments
ligaments that 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 what structures together
dura mater to segment above
highest level known to demonstrate hofmann ligaments
C6
proposed function of the cervical- upper thoracic hofmann ligaments
resist caudal movement of dural sac
resist gravitational forces on the dura and cord
lumbar Hofmann ligament attaches what structures together
dura mater to lower segmental levels
proposed function of the lumbar Hofmann ligaments
resist cranial movement of dural sac during flexion
proposed function of the proximal root sleeve ligament
resist displacement of PNS in the IVF
osseous conditions of lumbar vertebrae facilitating a spinal tap in this region
overlap of laminae, shingling, diminishes;
overlap of spinous processes, imbrication, diminishes
name of elevation near the origins of the lumbar transverse process
accessory process
a styloid process occurs with what frequency and as a result of what condition
7% occurrence as a realist of congenital elongation of the lumbar accessory process
ligaments that attach to the lumbar accessory process
mammillo-accessory ligament
parts of a vertebra that are attached via the mammillo-accessory ligament
mammillary process and accessory process of the same segment
believed to be entrapped by the mammillo-accessory ligament
medial branch of the dorsal rams of a lumbar spinal nerve
muscle(s) that attach to the lumbar accessory process

joint classification for the typical lumbar zygapophysis
synovial plane (diarthrosis arthrodia)
of synovial joints present on a typical lumbar vertebra
4
position of the lumbar zygapophysis in children
lies in the coronal plane
position of the lumbar zygapophysis in adults
saggital plane for L1/L2,L2/L3 and L3/L4
coronal plane for L4/L5 L5/S1
name given to the zygapophysis between vertebral couples that lie in the same plane
joint symmetry
names given to the condition in which one zygapophysis of a vertebral couple lies in the coronal plane or position and the other zygapophysis lies in the sagittal plane or position
joint asymmetry or joint tropism
name(s) of the condition in which the typical lumbar spinous process increases in length due to the aging process
Baastrups syndrome or “kissing spines”
muscles that will attach to the typical lumbar spinous process
