Back Flashcards
2 types of curvature and location
- Lordosis- C and L
2. Kyphosis - T and S
Lateral changes in spine
scoliosis
Make-up of vertebral arch
post. body, pedicles, lamina
joint between ant and posterior articular facets
z-joint
Features of C vert. (5)
- bifid spinous process
- short trans process
- Transverse foramen
- Small body
- Uncus on body
Features of T vert (3)
- Long spinous process
- Heart shaped vert. foramen
- Demifacets for ribs
Features of L vert
- Large kidney body
2. Thick, short processes
Features of atlas
!. no spinous process
- no body, but 2 lateral masses
- Short transverse with foramen
Features of axis
- 2 large sur articular facets
2. No body, but has odontoid process to connect with atlas
Joint b/w atlas and axis
atlanto-axial joint
Joint between atlas and skull
atlanto-occipital joint
Insides of disc
nucleus pulposus, anular rings
Ligaments of the spine (7)
- ligamentum flavum (lamina to lamina)
- Post. longitudinal lig. (lays over IV discs)
- Ant. longitudinal lig. (connects ant. spine)
- Transverse lig. (connects adj. transverse procs.)
- Interspinous lig. (connects inf. spinous procs.)
- Supraspinous lig (connects tips of spinous procs.)
- Nuchal lig. (connects occ. to C7 spinous process)
Level of illiac crests
L4/5
Level of PSIS
S2
Innervation of spinal column
Column - reccurent meningeal of SPINAL nerve
z-joints - articular branch of post. rami
Blood supply at each level
C -vert branches of aorta + asc cervical arts.
T - post. intercostals
L - Lumbar branches + subcostal art.
S - illiolumbar + sacral art.
Drainage of vertebrae
Neck - vertebral veins
Body - segmental veins
