cervical vertebrae body feature
small quadrangular body
cervical vertebrae foramen feature
triangular
cervical vertebrae spinous process feature
bifurcated
body of the thoracic vertebrae
medium sized and heart shaped
unique features of the cervical vertebrae
lateral and anterior lips that form the uncinate process and transverse foramen
vertebral foramen of the T vertebrae
is relatively small, about the size of the middle finger and is circular
spinous process of T vertebrae
long and inclined downward
superior articular processes for T vertebrae
face backwards and laterally
inferior articular process of T vertebrae
face forward and medially (expect for XII that faces laterally)
shape of the sacrum
concave anterior
what of the sacrum articulates with the coccyx?
apex
what does the sacrum articulate with laterally?
hip bones to form the sacroiliac joints
sacral promontory
is the anterior and upper margin of the first sacral vertebra that bulges forward
what is on either side of the promontory
two triangular flat surfaces called sacral ala
sacral foramina
are in the sacrum and form the sacral canal (sacral ala)
sacral hiatus
laminae of the 5th sacral vertebra and sometimes the 4th that fail to meet in the midline
median sacral crest
are the remnant of the spinous processes form this on either side of the crest
middle and lateral crests
are the remnants of the articular and transverse processes
anterior surface of the sacrum
is concave and has four foramina on each side for the passage of the anterior rami of the sacral nerves
transverse ridges
are on the sacrum and represent the remnant of intervertebral discs
sacral ala
are on either side of the promontory and are two triangular flat surfaces
superior aperture
aka pelvic inlet
first coccygeal vertebrae
is commonly not fused or incompletely fused with SIV
coccygeal corune
a vertical process arising from the first coccyx verebtral, towards the sacrum
