20
Q

if the c1 and c2 are atypical vertebrae, what classification is the cervical vertebrae 3-7

21
Q

typical; larger than the cervical; the only vertebrae to articulate with the ribs; heart shaped and has two costal facets

A

THORACIC VERTEBRAE

22
Q

massive; blocklike bodies; most of the stress on the vertebral column occurs in these regions

A

LUMBAR VERTEBRAE

23
Q

formed by fusion of 5 vertebrae; superiorly it articulates with 5th lumbar and inferiorly connects with the coccyx

24
Q

formed from the fusion of three to five tiny, irregular shaped vertebrae; human “tailbone”

25
a sideways curvature of the spine
SCOLIOSIS
26
an excessive forward rounding of the upper back
KYPHOSIS
27
is an exaggerated inward curve of the spine that typically affects the lower back
LORDOSIS
28
also called bulged, is a fragment of the disc nucleus that is pushed out of the annulus
