Q

Where the ribs articulate with the vertebrae

A

Costal facets

17
Q

Region of the back that is most injured. Absorbs most of the bodies weight and the weight we carry. Most of the motion occurs at L4-L5.

A

Lumbar spine

18
Q 
O= sternum and clavicle
I= mastoid process
A= bilat: flexes neck
      Unilat: laterally bends the neck, rotation to opposite
                  side
A

Sternocleidomastoid

19
Q

O= transverse processes of cervical vertebrae
I= ribs 1-2
A= bilat: assists neck flexion
Unilat: lateral bending of the neck

A

Scalene

20
Q

A= trunk flexion; compression of the abdomen

A

Rectus abdominis

21
Q

A= bilat: trunk flexion & compression of abdomen

Unilat: lateral flexion, rotation to opposite side

A

External obliques

22
Q

A= bilat: trunk flexion, compression of abdomen

Unilat: lateral flexion, rotation to same side

A

Internal obliques

23
Q

A= compression of abdomen

A

Transverse abdominis

24
Q

Can be static or dynamic, deals with alignment of various body segments

A

Posture

25
Q

This must be maintained at all times.

A

Vertebral alignment

26
Q

During gait; pelvis dips side to side

A

Lateral pelvic tilt

27
Q

Decrease the amount of stress placed on ligaments, muscles, and tendons. Improves function. Decreases amount of muscle energy needed to keep the body upright.

A

Good posture

28
Q

The worst position for you

A

Sitting
