Ch 7 Flashcards
Gelatinous core, gives disc resiliency and absorb shock, inner portion
Nucleus pulposus
Fibrocartilage surrounds inner portion, outer portion
Anulus fibrosus
Involve rupture of anulus fibrosus followed by protrusion of nucleus pulposus
Posterolaterally
Compression of a spinal nerve roots
Herniated intervertebral disc
Lacks a body and spinous process
Lateral mass on each side with articular facets
Flexion and extension
Atlas c1
Has Dens for rotation
Axis c2
Manubrium, sternal body, xiphoid process
Parts of the sternum
Superior part has clavicular notches articulate with 1st & 2nd ribs, clavicle and body of sternum
Manubrium
Largest part of sternum
Sternal body
Inferior end
Xiphoid process
Indentation in superior border of Manubrium
Jugular notch
Ridge across anterior surface of sternum where Manubrium joins body
Where 2nd ribs articulate with sternum anteriorly
Sternal angle
Prevents hyper extension of back
Anterior longitudinal ligament
Prevents hyper flexion of back
Posterior longitudinal ligament
Connects lamina of adjacent vertebrae
On posterior prevents hyperflexion
Ligamentum flavum
Articulate with clavicles , 1st and 2nd ribs, and Body of sternum
Clavicular notches
Bulk/majority of ribs
With costal grooves with blood vessels and nerves in them for protection
Body
Articulate with 2 different vertebral bodies
Head and neck
Articulate with transverse costal facets
Tubercle
Hit from behind
Hyperextend first ALL is torn, followed by hyperflexion tear PLL/lig flavum
Whiplash
Has transverse Foramen, articular facets point superior
Cervical vertebra
Articular facets face posteriorly
Costal facets
Oblique spinous process
Thoracic vertebra
Articular facets point medially
Short blunt spinous process
Lumbar vertebra
In between intervertebral discs
Intervertebral Foramen
