Facet
Facet orientation
Vertically - sagittal plane
Transverse processes
Projects laterally from junction of pedicels and lamina
Spinous processes
Projects dorsally and sometimes inferiorly
Posterior longitudinal
long
runs posterior to vertebral bodies and intervertebral discs
Extends from back of sacrum and gradually broadens
Anterior longitudinal
runs down anterior surface of spine, all vertebral bodies and intervertebral discs on ventral side
Ligamentum flavum
short but thick ligt, connects lamina over adjacent vertebrae, preserves upright posture and assists vertebral column in resuming shape after flexion
Interspinous
connects spinous processes of adjacent vertebrae
Supraspinous
connects tips of adjacent spinous processes
Rectus sheath
anterolateral abdominal wall
anterior layer – EO & IO
posterior layer - IO & TA
layers interlace at midline – linea Alba
Thoracolumbar fascia
posterior layer – superficial TP erector spinae & attached to sp
middle layer – between erector spinae and quadratus lumborum attached to transverse tips
anterior layer – deep to quadratus lumborum, attached to ant. Of TP
