BIO 271 UNCG Practical #1 Lab Exercise 1 Questions With
Complete Solutions
body of vertebrae
the thick, disc-shaped anterior portion which is the weight
bearing portion
vertebral arch
structure that encloses the nerve cord
pedicles of vertebrae
"pedicle=supporting column/stalk" makes up the extrusions of
the vertebral arch, connects to the body
laminae of vertebrae
"lamina=flat plate-like surface" make up vertebral arch;
flattened plates that fuse in the median plate, completing the
arch posteriorly
Spinous process of vertebra
sharp, slender projection. makes up the boney spinal area you
can feel on your back
Transverse process of vertebra
"arms of the vertebra" C1-C7 (Cervical vertebrae) DO NOT
HAVE THESE. They form joint with ribs in thoracic region, site
for muscle attachment in lumbar region
inferior articular process
,The articular process on the bottom of the vertebrae.
Axis (C2)
second cervical vertebrae
Dens of axis (C2)
upward projection connecting to the axis
costal facets of thoracic vertebrae
T1-T10 transverse processes - these articulate with the tubercles
of the ribs. meeting point of ribs to vertebrae.
Lumbar Vertebrae (L1-L5)
the third set of five larger vertebrae, which forms the inward
curve of the spine
Difference of vertebrae
Thus, cervical vertebrae are smaller than lumbar
vertebrae due to differences in the proportion of body weight
that each supports. Thoracic vertebrae have sites for rib
attachment, and the vertebrae that give rise to the sacrum and
coccyx have fused together into single bones.

Segments of the spine
, cervical, thoracic, lumbar, sacrum, coccyx
Sacrum
bone formed from five vertebrae fused together near the base of
the spinal column
auricular surface of sacrum
Can only be seen from posterior view, articulation with ilium
(large flat hip bone)
median sacral crest of sacrum
remnant of the spinous processes of the fused vertebrae. boney
and bumpy median
sacral foramina
holes in sacrum
sacral canal
Continuation of the vertebral canal that goes inside the sacrum
and terminates near the coccyx via an enlarged opening called
the sacral hiatus.
superior articular process of sacrum
paired processes that extend upward from the sacrum to
articulate (join) with the inferior articular processes from the L5
vertebra
promontory of sacrum
Ridge projecting along the anterior edge of the body of S1
sacral hiatus
