1
Why is the posterior curve also called the primary curve?
It is the first curve to appear embryologically
2
What are the adult remnants of the primary curve along the vertebral column?
The thoracic or dorsal curve and the pelvic or sacrococcygeal curve
3
What are the names given to curves which form during development to reverse the direction of the regions along the vertebral column?
Anterior curve, secondary curve, compensatory curve
4
What are the names of the anterior curves, secondary curves, and compensatory curves?
Cervical curve and lumbar curve
5
What is the earliest time of appearance of the cervical curve?
The third fetal month
6
What is the traditional time of appearance of the cervical curve said to be?
During the last trimester in utero
7
What is the time during which the "adult" cervical curve is said to appear?
Within the first year after birth
8
What developmental events are indicated in the formation of the adult cervical curve?
1. Centers for vision and equilibrium will appear in teh brain
2. Musculature attaching the skull, cervical region, and upper thorax together develops
3. The head is held upright
4. The intervertebral disc height becomes greater anterior than posetrior
9
At what age will the infant begin to hold the head erect?
Usually between the third and fourth month after birth
10
What is the name given to the integration of visual and motor pathways associated with holding the head erect?
The righting reflex
11
What is the location for the cervical kyphosis?
Between occiput and C1
12
What is the time of appearance of the lumbar curve?
Between 12 and 18 months after birth
13
What infant activities are associated with the developmental of the lumbar curve?
Crawling and walking
14
What developmental events are indicated in the formation of the adult lumbar curve?
1. Crawling will cause the abdomen to put tension on the lumbar region and pulls it forward
2. Muscle development is promoted to compensate for the swayback of the lumbars
3. Intervertebral disc height will become greater anterior compared to posterior
4. Walking will further promote muscle and intervertebral disc development
15
What is the vertebral relationship between the lumbar curve and the lumbar enlargement?
Lumbar curve T12-L5; lumbar enlargement T9-T12
16
What is the formation of the lateral curve often correlated with?
Faster development of the muscles on the side of handedness
17
What is the formation of the lateral curve often correlated with?
Faster development of the muscles on the side of handedness
18
What is the time of appearance of the lateral curves?
They appear after 6 years old
19
What names are given to conditions associated with abnormal curves of the vertebral column?
Lordosis, kyphosis, socliosis
20
What is the definition of lordosis?
A forward bending condition
21
What is the definition of kypyhosis?
A humpback or hunchback condition
22
What is the definition of scoliosis?
A warped or crooked condition
23
What clinical examples of abnormal curvatures along the vertebral column were stressed in class?
Military neck, humpback or hunchback, and swayback
24
What is military neck?
A decreased anterior curve in the cervical region, a straight neck
25
What is humpback or hunchback?
An increased posterior curve in the thoracic region
26
What is swayback?
An increased anterior curve in the lumbar region
27
What does the used o the term lordotic try to imply?
A normal cervical and normal lumbar anterior curve
28
What dose the used of the term kyphotic try to imply?
A normal thoracic or dorsal and normal pelvic or sacrococcygeal posterior curve
29
What prefixes are used to convey abnormality in curve patterns?
Hyper and hypo
