The Back Flashcards
vertebral body
strength to vertebral column & support body weight
vertebral notches
formed from the projection of the body & articular processes superior & inferior to the pedicles
functions of parts in the vertebra
spinous/transverse process: muscle attachment
articular processes: limit movement
vertbral arch: protection of spinal cord
articular process
4 form the zygapophysial (facet) joint;
the direction of the joints determines types of movement & restriction between adjacent vertebrae
joints of vertebral bodies
symphyses- designed for weight bearing & strength
what is related to ROM
the thickness of vertebral discs
uncovertebral joints
located between the uncus of C3-6
anterior longitudinal ligament
covers & connects the anterolateral aspect of the VB and IV discs (extends from the pelvic surface of the sacrum to anterior tubercle of C1)
maintains stability of IV joints and limits extension of VC
posterior longitudinal ligament
runs w/in the vertebral canal
prevent hyperflexion of VC
facet joints
between superior/inferior articular processes
permit gliding movements between articular processes
ligmamenta flava
bind lamina of the adjoining vertebrae
resist separation of vertebral laminae by arresting abrupt flexion of VC; help w/ posture and assist column after flexing
interspinous & supraspinous ligaments
unite adjacent spinous processes
nuchal ligament
substitutes for bone providing attachment for C3-5
craniovertebral joints
alanto-occipital joint (atlas, C1) & alanto-axial joints between C1 & C2
no IV discs; provide wider ROM
alanto occipital joints
allow nodding of the head
