Flashcards in Development of vertebral column Deck (13):
1

What regions is the primary curvature retained throughout life

Thoracic
Sacral
Coccygeal

2

Definition of kyphosis

Curvature that is concave anteriorly
They are primary curvatures

3

Definition of lordosis

Curvature that is concave posteriorly
They are secondary curvatures

4

How many curvatures in adult VC

4 (2 kyphoses and 2 lordoses)

5

Advantages of curvature of adult VC

4 curvatures gives it great flexibility and resilience

6

Where are the kyphoses of the adult VC

Thoracic
Sacrococcygeal

7

Where are the lordoses of the adult VC

Cervical
Lumbral

8

How does the VC change during pregnancy

Lumbar lordosis exaggerates as centre of gravity shifts anteriorly

9

What's the first secondary curvature to develop
How does it develop

Cervical lordosis
Develops as baby starts to lift its head

10

How does the lumbar lordosis develop

Lumbar region loses its primary curvature during crawling
Develops when child begins to stand up and walk

11

What points of the adult VC does the centre of gravity pass through
What's the significance of this

C1/C2
C7/T1
T12/L1
L5/S1
These are weak points

12

What happens to VC in the elderly

Senile kyphosis
Secondary curvatures begin to disappear and primary curvature is re-established

13

How many curvatures in foetal VC
What is this known as

1 - Kyphosis
Primary curvature
