Ch 8&9 Cervical and Thoracic Spine,
Lumbar Spine, Sacrum, and Coccyx
vertebral column - CORRECT ANSWER-commonly called the spine or spinal
column
vertebrae - CORRECT ANSWER-is a complex succession of many bones
(singular is vertebra). provides a flexible supporting column for the trunk and
head and also transmits the weight of the trunk and upper body to the lower
limbs.
spinal canal - CORRECT ANSWER-follows the various curves of the spinal
column and begins at the base of the skull and extends distally into the sacrum.
What does the spinal canal contain? - CORRECT ANSWER-the spinal cord and
is filled with cerebrospinal fluid.
spinal cord - CORRECT ANSWER-enclosed and protected by the spinal canal &
begins with the medulla oblongata of the brain.
The spinal cord passes through which part? - CORRECT ANSWER-through the
foramen magnum of the skull and continues through the first cervical vertebra all
the way down to the lower border of the first lumber vertebra where it tapers off to
a point called the conus medullaris.
intervertebral disks - CORRECT ANSWER-tough fibrocartilaginous disks
separate typical adult vertebrae and are cushion-like disks that are tightly bound
to the vertebrae for spinal stability but allow for flexibility and movement of the
vertebral column.
The vertebral column is divided into? - CORRECT ANSWER-five sections which
are cervical and thoracic vertebrae and the last three sections are the lumbar
vertebrae, sacrum, and coccyx.
, The first 7 vertebrae are known as? - CORRECT ANSWER-the cervical
vertebrae
The average person has how many cervical vertebrae? - CORRECT
ANSWER-seven
The next 12 vertebrae are known as the? - CORRECT ANSWER-thoracic
vertebrae
Each of the thoracic vertebrae are connected to? - CORRECT ANSWER-a pair
of ribs
What's the older term used for thoracic? - CORRECT ANSWER-dorsal spine
What's the largest individual vertebrae? - CORRECT ANSWER-the five lumbar
vertebrae. These are the strongest in the vertebral column because the load of
body weight increases toward the inferior end of the column.
What are the common sites of injury and pathology for the lumbar vertebrae? -
CORRECT ANSWER-the cartilaginous disks between the inferior lumbar
vertebrae
sacrum & coccyx - CORRECT ANSWER-develop as multiple separate bones
and then fuse into two distinct bones
A newborn has how many sacral segments? - CORRECT ANSWER-5
A newborn has how many coccygeal segments? - CORRECT ANSWER-3-5
(average of 4)
In a young adult, what's the average bones in the vertebral column? - CORRECT
ANSWER-33
After fusion into a single sacrum and a single coccyx, the adult vertebral column
is composed of how many bones? - CORRECT ANSWER-26 separate bones
