Spine Non-Contractile Week 3 Flashcards
Functions of vertebral column
Protection, Support, Movement (except sacrum/coccyx), Muscle Attachment
Features of typical vertebrae
Body, Arch (Pedicles, Lamina), Foramen, Transverse Process, Articular Processes/Facets, Pars Interarticularis
Where do spinal nerves exit the spinal cord
Intervertebral foramen
Atlanto-Occipital Joint Classification
Synovial (YES)
Atlanto-Axial Joint Classification
Synovial (NO)
Uncovertebral Joint Location/Function
C3-C7, limits lateral flexion
Intervertebral Discs Function
Binds vertebrae together, absorbs shock, limits movement to protect spinal cord/meninges
Amount of Movement at each IV joint
Limited (combined movement creates a large amount of movement)
Craniovertebral Joint Ligaments (Location/Function)
Limit movement at C0-C1 and C1-C2 instead of IV discs
Transverse Ligament of Atlas function
Limits dens from moving posteriorly
Nuchal Ligament Attachments/Limits
S: External Occipital Protuberance
I: Cervical Spinous Processes (down to C7)
Limits: Head falling forward
Supraspinous Ligament
S: C7 tip of spinous process
I: Sacrum
Limits: Flexion
Interspinous Ligaments
S: Superior Spinous Process
I: Inferior Spinous Process
Limits: Anterior translation, flexion
Anterior Longitudinal Ligament
S: Anterior C1 vertebrae/occipital bone
I: Anterior Sacrum
Limits: Hyperextension
Posterior Longitudinal Ligament
S: C2 discs/vertebral bodies
I: Posterior sacrum
Limits: Flexion
