Exaggeration in the sagittal curvature in Thoracic Column
Kyphosis
Exagerration in the sagittal curvature in Lumbar Column
Lordosis
Lateral Deviation of the spinal cord
Scoliosis
Most common part of vertebral column for scolosios

Sacral
Convex Curvature Ventrally
Cervical
Lumbar
Sacrum
Primary Curvature of vertebral column
Thoracic and Sacral
Concave Ventrally
Secondary Curvature of vertebral colun
Cervical and Lumbar
Convex Ventrally
characteristic feature of first cervical vertebrae
absent body
characteristic feature of second cervical vertebrae
odontoid process/dens
characteristic feature of seventh cervical vertebrae
long spinous process and not bifid
Also called vertebra prominens

C1
Axis
C2
Characteristic of Cervical Vertebrae
- transverse process have Foramen Transversarium
- Spines are short and bifid
- body is small and broad
- vertebral foramen is large and triangular
- superior articular processes have facets that face posteriorly and superiorly
- Inferior articular process face inferiorly and anteriorly
Subclavian artery is divided into how many parts
3
What divides the subclavian arrtery?
Scalenous anterior muscle
First part of subclavian artery
- vertebral
- thyrocervical
- internal thoracic
Second part of subclavian artery
- costocervical
Third part of subclavian artery
None
Heart Shaped Body
Thoracic Vertebra
Facets on the bodies of the thoracic vertebra are for
articulation with HEAD of ribs
Facets on the transverse process of the thoracic vertebra are for
articulation with TUBERCLE of ribs
Characteristic of Thoracic Vertebra
- medium size
- heart shaped
- vertebral foramen is small and circular
- spines are long
- body facet - articulation with head of rib
- transverse process facet - articulation with tubercle of ribs
Characteristic of Lumbar Vertebra
- body is large
- kidney shape
- pedicles are strong and directed backward
- laminae are short in vertical dimension
- vertebral foramina are triangular
- transverse process are long and slender
- spinous process are short, flat, and quadrangular; project posteriorly
