Spine/Back Flashcards
GSA
Proprioception (GTO, MS) Exteroceptive (Pain and temp)
GSE
Innervate skeletal muscle
GVA
distention, pain from “viscera” (think gut or sweat glands, arrector pili)
GVE
autonomic, smooth muscle and gland innervation
Dermatome
area of skin innervated by cutaneous branches of spinal nerve
Sacralization
Fusion of the L5 with S1 ( only have 4 L vertebrae)
Lumbarization
Lack of fusion of S1 with Sacrum (6 lumbar vertebrae)
Number of vertebrae
33 ( 5C 12T 5L 5S 4C)
Body of vertebrae
largest part, most anterior
spongy on the inside, Compact on the outside
Covered by hyaline cartilage
What passes through the Transverse Cervical Foramen
Vertebral artery, vein and sympathetic plexus
Cervical superior articular processes
Flat
Obliquely in the coronal plane
why is the vertebral foramen of C1 enlarged
to accommodate the brain stem
C7
Vertebra prominens
May lack transverse foramina
- if they are there, only transmit vertebral vein
Complete Costal Facet
located on TV 1 10 11 12
Thoracic superior articular process
Vertically in the coronal plane
Face posterior
Lumar Superior Articular Process
Vertically in the sagittal plane
Lumbar Puncture
facilitated by short non-overlapping Laminae
L5/L5 (adult)
Lower in children
(spine ends L1/L2
Ala of sacrum
fused costal and transverse processes of SV1
Intervertebral discs (Structure)
outer= anulus fibrosis: concentric rings of fibrocartilage, attaches to body by hyaline cartilage
Inner= elastic, hydrated, gelatinous mass that can move under compression
Intervertebral discs
Thicker anterioral (C and L regions) to maintain secondary curves Absorb shock (can bulge past the margins under compression)
