1

## What are the effects of a hyperlordotic curve

###
posterior disc compression

tensile stress anteriorly to the disc and myofascial structures

Shortening of posterior musculature

possible predisposition to facet syndrome

2

## What are the effects of a hypolordotic curve

###
compression of the anterior disc

prolonged stress on the posterior ligaments

shortening of anterior cervical muscles

protective splinting

3

## What is the degrees of flexion in the cervical spine

### 60˚

4

## What is the GROM for extension in the cervicals spine

### 75˚

5

## What is the GROM for lateral flexion in the cervical spine

### 45˚ to each side

6

## What is the GROM for rotation in the cervical spine

### 80˚ chin to shoulder

7

## What are the big trends for flexion extension in the cervical

###
Most in CO-C1

Least C2-3, and C7-T1

8

## What is the combined range for flexion/extension of C0-1

### 25˚

9

## What is the IAR for flexion/extension CO-C1

### just above odontoid

10

## What is the paradoxical movement of the occiput for flexion/extension

### during cervical flexion a large percentage of the population will extend at CO-C1 at end range of cervical flexion

11

## During flexion what direction is the roll? What direction is the slide?

###
Roll: Anteriorly

Slides: Posteriorly

12

## What is the SROM for lateral flexion at CO-C1

### 5˚ each side

13

## What limits the lateral flexion of CO-1

### Alar ligaments

14

## What is the IAR for lateral flexion of C1-0

### located midway between odontoid tip and EOP

15

## What is occuring on the articular surface of CO-1 during lateral flexion

### C0 is gliding down the ipsilateral articular surface while the contralateral side glides up

16

## What are the two patterns of motion of lateral flexion in C0 - C1

###
Predominately a movement in the coronal plane

coupled with contralateral rotation

17

## What is the SROM of rotation of CO-1

### 5˚ to each side

18

## What occurs at the articular surface during rotation of CO-1

### C0 articular surface slides posterior and superior on the ipsilateral articular surface of C1. On the contralateral side it slides anterior and superior

19

## What is the main feature of the C1-2 joint articulation besides the odontoid

### That the facets of both bones are convex

20

## What is the type of cartilage lines the posterior portion of the ondontoid

### fibrocartilage

21

## What is the SROM for flexion/extension at C1-2

### Combined motion of 20˚

22

## What is the IAR for flexion/extension C1-2

### middle third of dens

23

## What is the pattern of motion for C1-2

### angular sagittal plane motion coupled with sagittal plane translation

24

## What happens in flexion at the joint articulation of C1-C2

### posterior jt surfaces and posterior arches separate while C1 articular surface slides posteriorly

25

## What is the SROM of lateral flexion of C1-2

###
limited

5˚ to each side

26

## What happens at the articular surfaces during lateral flexion at C1-2

### C1 translates on the C2 articular surfaces toward the side of lateral flexion

27

## What is the SROM of rotation at C1-2

###
Huge!

40˚ to each side

28

## How much of cervical rotation occurs at the C1-2 articulation

### ~1/2

29

## How degrees of rotation occur exclusively at C1-2

### The first 25˚
