Vertebrae and Spine Flashcards
Features unique to thoracic
Costal facets
Features unique to cervical
Transverse foramen, bifid spinal process
Which vertebre have bifid spinous process?
C2-C6
Vertebra with no body, and divets that articulate with occipital condyles
Atlas
Vertebra with a dens projection
Axis
What passes through vertebral foramen
Spinal cord
What passes through intervertebral foramen?
Nerves
What passes through transverse foramen?
Blood vessels
Only cervical vertebra without bifid spinous process
Vertebrae prominens (C7)
What does the superior articular facet of C2 atticulate with
Inferior articular facet of C1
Gel material (collagen fibers) that pads intervertebral spaces
Nucleus pulposus
Fibrocartilage ring covering intervertebral space
Annulus fibrosus
Ribs 1-7, have their own costal hyaline attachment to sternum
True ribs
Ribs 8-12, do not have their own costal hyaline attachment
False ribs (8-10 connect to 7’s cartilage)
Ribs 11 and 12, which are not attached to the sternum at all
Floating ribs
Rib and vertebrae points of contact
Rib head sits between costal facets of two vertebra, tubercle rests on transverse costal facet of inferior vertebra
Runs from external occipital protuberance to vertebra C7. Stabilizes the head.
Ligamentum nuchae
SCM, midline of neck, mandible
Anterior triangle of the neck
Trapezius, SCM, clavicle
Posterior triangle of the neck
Deepest abdominal muscle (and ONLY compresses abdomen)
Transverse abdominis
Most superficial abdominal muscle
External oblique
Bending head forwards
Cervical flexion
Bending head backwards
Cervical extension
Ear to shoulder
Cervical lateral flexion
Turning head
Cervical rotation
Bending upper back back and forth
Thoracic extension and flexion
Border of ribcage
Costal margin
