vertebral column Flashcards
how many irregular bones are there in the vertebral column
26 IRREGULAR BONES
how many cervical vertebrae
7 CERVICAL VERTEBRAE
how many thoracic vertebrae
12 THORACIC VERTEBRAE
how many lumbars are there
5 LUMBAR VERTEBRAE
flexible fibrocartilage that separate individual vertebrae; and this is shock absorber
INVERTEBRAL DISCS
2 curves
PRIMARY CURVATURES
SECONDARY CURVATURES
thoracic and sacral regioon produce C-shape
PRIMARY CURVATURES
cervical and lumbar; it allows to center our body weight
SECONDARY CURVATURES
6 common features of the vertebrae
BODY/ CENTRUM
VERTEBRAL ARCH
VERTEBRAL FORAMEN
TRANSVERSE PROCESSES
SPINOUS PROCESS
SUPERIOR & INFERIOR ARTICULAR PROCESS
a feature of the vertebrae that is a disclike, weight-bearing part facing anteriorly in the vertebral column
BODY/ CENTRUM
a feature of the vertebrae that form from the joining of all posterior extensions (laminae and pedicles)
VERTEBRAL ARCH
a feature of the vertebrae that canal through which spinal cord passes
VERTEBRAL FORAMEN
a feature of the vertebrae that two lateral projections form the vertebral arch
TRANSVERSE PROCESSES
a feature of the vertebrae that are single projection arising from posterior aspect of vertebral arch (fused laminae)
SPINOUS PROCESS
a feature of the vertebrae that are paired projections lateral to the vertebral foramen; allows vertebrae to form joints with adjacent vertebrae
SUPERIOR AND INFERIOR ARTICULAR PROCESSES
the 1st cervical vertebrae is atypical called
ATLAS
the 2nd cervical vertebrae is atypical called
AXIS
atlas and occipital forms the yes joint called
ATLANTO-OCCIPITAL JOINT
atlas and axis forms the no joint called
ATLANTO-AXIAL JOINT
if the c1 and c2 are atypical vertebrae, what classification is the cervical vertebrae 3-7
TYPICAL
typical; larger than the cervical; the only vertebrae to articulate with the ribs; heart shaped and has two costal facets
THORACIC VERTEBRAE
massive; blocklike bodies; most of the stress on the vertebral column occurs in these regions
LUMBAR VERTEBRAE
formed by fusion of 5 vertebrae; superiorly it articulates with 5th lumbar and inferiorly connects with the coccyx
SACRUM
formed from the fusion of three to five tiny, irregular shaped vertebrae; human “tailbone”
COCCYX
a sideways curvature of the spine
SCOLIOSIS
an excessive forward rounding of the upper back
KYPHOSIS
is an exaggerated inward curve of the spine that typically affects the lower back
LORDOSIS
also called bulged, is a fragment of the disc nucleus that is pushed out of the annulus
HERNIATED DISCS
