Vertebral Column L.o.'s

Front 1

Identify main structures of adult vertebral column

Back 1

five types of vertebrae:
7 cervical
12 thoracic
5 lumbar
5 sacral
3-5 coccygeal

Front 2

How many vertebrae are mobile in the vertebral column

Back 2

24 of 33 vertebrae

Front 3

Vertebral column provides what?

Back 3

1. strong and flexible support for trunk
2. protects spinal cord and nerve roots
3. plays role in posture, support of body weight, and locomotion

Front 4

Basic curvatures of the vertebral column

Back 4

1. Cervical (secondary): convex anteriorly
2. Thoracic (primary): concave anteriorly
3. Lumbar (secondary): convex anteriorly
4. Sacrococcygeal (primary): concave anteriorly

Front 5

Abnormal Curvatures of the back include ______________

Back 5

1. Scoliosis
2. Kyphosis
3. Lordosis

Front 6

Scoliosis is:

Back 6

any lateral curvature of the spine in the thoracic, lumbar, or thoracolumbar area. The curvature is designated right or left according to the convex side of the major curve.

Front 7

What is the most common type of scoliosis in adolescent females?

Back 7

Idiopathic right thoracic scoliosis.
This means that it is structural and irreversible.
Right convex curve in thoracic region

Front 8

Kyphosis is ___________

Back 8

a curvature that is convex posteriorly

Front 9

Clinical correlation of Kyphosis:

Back 9

osteoporosis, kyphosis of the thoracic spine may occur after compression fractures of the vertebal bodies.
It is most common in postmentopausal women

Front 10

Lordosis is ____________

Back 10

a curvature that is convex anteriorly

Front 11

Clinical correlation of ligaments of the vertebral column
Posterior Longitudinal ligament

Back 11

the PLL reduces the change of herniations that may compress the spinal cord and cauda equina because it reinforces the IV disc posteriorly

Front 12

Ligamentum flavum clinical correlation

Back 12

the spinal cord may be injured after transient inward bulging of the ligamentum flavum during sudden forced hyperextension.

Front 13

Anterior longitudinal ligament clinical correlation

Back 13

whiplash is a forceful hyperextension of the cervical spine that stretches the ALL. Rear-end collisions cause whiplash. Symptoms include rapid onset of neck pain, headache, and pain & numbness radiating into the upper extremities

Front 14

mobility of the vertebral column arises from ______________

Back 14

compressibility and elasticity of the intervertebral disc

Front 15

What does the amount of movement depend upon of the vertebral column

Back 15

amount of movement depends upon the ratio between the height of the discs and the vertebral column

Front 16

Actions of ligaments and muscles are checked by ___________. This contributes to the wide range of motion

Back 16

Articular capsule joint

Front 17

What is the main function of the transverse and spinous processes

Back 17

The transverse and spinous processes mainly provide an attachment site for muscles and ligaments. The planes of articulation of the articular process vary with each region, which allows for different degress of lateral flexion and rotation.
