Module 11: Vertebral Column and Trunk
Wall (Anatomy 337 UW Madison Exam 2)
Vertebraes are connected by what? How many bones make up the vertebral
column? - -Intervertebral discs, 26 bones!
- Describe the vertebral column
What does it protect? - -It is a flexible column that supports the head, neck,
and body and allows for their movements.
It also protects the spinal cord, which passes down the back through
openings in the vertebrae.
- Describe regions of the vertebral column. - -C1-C7
T1-T12
L1-L5
Sacrum (made of five fused sacral vertebrae)
Coccyx (made of three to four fused coccygeal vertebrae)
- Primary curves are retained from the original fetal curvature (born with)
What are the two primary curves? - --thoracic curve
-sacrococcygeal curve
- secondary curvatures develop after birth. (born with)
What are the two secondary curves?
Why do they develop? - --cervical curve
-lumbar curve
They develop as we start walking, standing up right
- What are spinal curves function? - -These curves increase the vertebral
column's strength, flexibility, and ability to absorb shock
- Scoliosis? LMAO YOU - -Scoliosis is an abnormal lateral bending of the
vertebral column.
- Kyphosis? - -The excessive curvature of the upper thoracic vertebral
column is called kyphosis
- Lordosis? - -Lordosis is an excessive curvature in the lumbar region of the
vertebral column.
Ex) Excessive weight in abdomen can cause it like pregnancy!!!
, - What does a typical vertebrae consist of? - -a body, a vertebral arch, and
seven processes.
- What is the body of the vertebrae? - -The body is the anterior portion of
each vertebra and is the part that supports the body weight.
- What does the vertebral arch do?
-What forms the arch?
-What arises from the vertebral arch?
-What does it contain? - -The vertebral arch forms the posterior portion of
each vertebra
-The seven processes
-Vertebral foreaman where spinal cord is
- What are the seven processes?
What do they do? - --transverse (paired)
-spinous (single)
-superior articular (paired)
-inferior articular (paired)
-play a major role in determining the type and range of motion available in
each region.
- Why is C1 called the atlas?
-Does the atlas have a body or spinous process?
-If not, what does it consist of instead? - -because this vertebra supports the
skull on top of the vertebral column
-no, it does not have a body or spinous process.
-It consists of an anterior and a posterior arch and elongated transverse
processes.
- Why is C2 called the axis?
-What does the axis have projecting upward?
-What do these articulate with? - -because it serves as the axis for rotation
when turning the head toward the right or left.
=The axis (C2 vertebra) has the upward projecting dens, -which articulates
with the anterior arch of the atlas.
- Thoracic vertebrae or distinguished by what?
What does it have for rib attachment? - -by the spinous process, which is
long and projects downward to overlap the next inferior vertebra.
