Typical Lumbar Spine: L1-L4 Flashcards
generic shape of typical lumbar vertebral body from CRANIAL view
reniform or kidney shaped
accounts for direction of the lumbar curve
the vertebral body and intervertebral disc = greater anterior height than posterior height
of joint surfaces present on the vertebral body of typical lumbar
6
of synovial joints on typical lumbar vertebral bodies
NONE
of cartilaginous (amphiarthrosis) symphysis joint surfaces on typical lumbar vertebral body
2
of FIBROUS (amphiarthrosis) syndesmosis joint surfaces on typical lumbar vertebral bodies
4
muscles attached to the first lumbar vertebral body
psoas maj.
psoas min.
muscles attached from L2-L4 vertebral bodies
psoas maj.
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
