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
