Vertebral column Flashcards
Functions of vertebral column
- transmit body weight
- protects spinal cord
Curvatures of the vertebrae
cervical= secondary thoracic= primary lumbar= secondary sacral= primary primary= congenital secondary = developmental
intervertebral disc cartilage
annulus fibrosus - ligament
holding disc in place which prevent nucleus pulposus squeezing out
Ligaments of the vertebral column (6)
What is the joint between vertebrae and rib
costovertebral joint
Joint between articular processes
zygopopheseal joint
joint between vertebral bodies and intervetebral discs
amphirarthroidal joints
Cervical vertebrae
- Small size
- Transverse foramina
- Saddle-shaped body
- Bifid spinous process
Feature of C1 (Atlas)
- no body/spinous process
- consists of anterior and posterior arches and two lateral masses
- Superior surfaces of lateral masses articulate with occipital condyles
Feature of C2 (Axis)
- Dens projects into anterior arch of atlas
- Prominent spinous process
Feature of thoracic vertebrae
- 12 vertebrae
- articular facets on coronal plane
- heart shape to kidney shape
- spinous process inferior
Feature of T1
Single whole superior costal facet
Feature of T10
Single whole superior facet
Feature of T11 and 12
no transverse facet, only superior costal facet
Feature of 12/transitional
Spinous process more lumbar, inf articular facets deviate laterally and curved
