VERTEBRAL COLUMN
VERTEBRAL COLUMN
FUNCTION supporting axis of the body protection for the spinal cord
SYNONYMS spinal column, backbone, spine
VERTEBRAL COLUMN
CURVATURES cervical, thoracic, lumbar, sacral
DIVISION cervical, thoracic, lumbar, sacral, coccygeal
COMPONENTS intervertebral discs and vertebrae
CURVATURES OF THE VERTEBRAL COLUMN
4 CURVATURES IN TOTAL cervical - secondary thoracic - primary lumbar - secondary sacral - primary
SCOLIOSIS abnormal, sideways curvature of the spine dextroscoliosis (thoracic)/ levoscoliosis (lumbar)
SCOLIOSIS
DIVISION
CERVICAL VERTEBRAE C1 - C7 atlas, axis, vertebra prominens bony aspect of the neck
THORACIC VERTEBRAE T1 - T12 thoracic = rib cage
LUMBAR VERTEBRAE L1 - L5 strongest and largest
SACRUM curved, triangular shape “S1 - S5”, sacral bones at birth
COCCYX tailbone Co1 - Co4 fused / separate vertebrae with limited movement
COMPONENTS
VERTEBRA an individual
backbone vertebral body
exception : atlas lumbar vertebrae -
large bodies vertebral=neural
arch: 2x laminae + pedicle
COMPONENTS
vertebral foramen between arch and
body triangular, round spinal=vertebral
canal, spinal cord intervertebral foramen
formed by the juxtaposition of superior and inferior notches in the pedicles
processes transverse -
articulation with ribs, lumbar vertebrae have mammillary and accessory processes
superior and inferior articular processes = zygapophyses, articulation with other vertebrae
spinous - located at the posterior aspect of the neck, in the midline, easily palpable from C7
COMPONENTS
INTERVERTEBRAL DISCS between vertebrae outer fibrous and central
semi- fluid part bind the vertebrae give flexibility shock absorbers
SCIATICA pain caused by pressure on
the sciatic nerve prolapsed intervertebral disc
nucleus pulposus escapes posterolaterally
VOCABULARY RECAP
VERTEBRAL COLUMN spinal column, backbone, spine
PRIMARY AND SECONDARY CURVATURES thoracic, sacral, cervical, lumbar
SCOLIOSIS abnormal curvature of the spine dextroscoliosis, levoscoliosis
THORACIC = RIB CAGE bony enclosing wall of the chest consisting chiefly of the ribs
and structures connecting them COCCYX
tailbone ZYGAPOPHYSES
superior and inferior articular processes SCIATICA
pain caused by pressure on the sciatic nerve
