1

How many articulating vertebrae?

24

2

How many fused vertebrae?

9

3

How many cervical, thoracic, lumbar, sacrum, and coccyx?

• 7 Cervical (neck) vertebrae
• 12 Thoracic (chest) vertebrae
• 5 Lumbar (lower back) vertebrae
• 5 Sacrum (posterior pelvic girdle) vertebrae
• 4 Coccyx (tail bone) vertebrae

4

What kind of curve does your cervical have?

Lordotic

5

What kind of curve does your thoracic have?

Kyphotic

6

What kind of curve does your lumbar have?

Lordotic

7

What is the purpose of the curvature?

• Increase strength
• Absorption of forces

8

Increased posterior concavity of lumbar & cervical curves

Lordosis (bent backwards)

9

Increased anterior concavity of thoracic curve

Kyphosis

10

Reduction of normal lordotic curve, resulting in a flat-back appearance

Lumbar kyphosis

11

Lateral curvatures or sideward deviations of spine

Scoliosis

16

What is the most mobile articulation of the spine?

Atlanto-axial joint

17

What kind of joint is the atlanto-axial joint?

Pivot

18

Central gelatinous, pulpy substance

Nucleus pulposus

19

Vertebral Column Flexor Muscles:

• Rectus Abdominis
• External Oblique
• Internal Oblique
• Psoas Major (With origin fixed)
• Iliacus (with origin fixed)

20

Origin of rectus abdominis:

Pubic crest, pubic symphysis

21

Insertion of rectus abdominis:

Cartilage of 5th-7th ribs and xiphoid process

22

Action of the rectus abdominis:

• Flex the vertebral column
• Tilt pelvis posteriorly

23

Origin of the external oblique:

External surfaces of 5th -12th ribs

24

Insertion of the external oblique:

Anterior part of the iliac crest, abdominal aponeurosis to linea alba

25

Action of the external oblique:

- Bilaterally:
• Flex the vertebral column
• Compress abdominal contents
-Unilaterally
• Laterally flex vertebral column to same side
• Rotate vertebral column to the opposite side

26

Aponeurosis is deep to the:

Rectus abdominis

27

Origin of the internal oblique abdominals:

Lateral inguinal ligament, iliac crest and thoracolumbar fascia

28

Insertion of the internal oblique abdominals:

Internal surface of lower three ribs, abdominal aponeurosis to linea alba

29

Action of the internal oblique abdominals:

- Bilaterally:
• Flex the vertebral column • Compress abdominal contents
- Unilaterally
• Laterally flex vertebral column to the same side
• Rotate vertebral column to the same side

30

Origin of the transverse abdominis:

Lateral inguinal ligament, iliac crest, thoracolumbar fascia and internal surface of lower 6 ribs

31

Insertion of the transverse abdominis:

Abdominal aponeurosis to linea alba

32

TVA, and obliques are responsible:

Stability of the core when doing other exercises

33

Action of the transverse abdominis:

Compress abdominal contents

34

Extension and ipsilateral side flexion

Erector spinae group
• Spinalis
• Longissimus
• Iliocostalis

35

Extension & contralateral rotation

Transversospinalis group
• Multifidi
• Rotatores
• Semispinalis Capitis

36

Extension, ipsilateral rotation, & lateral flexion

• Capitus
• Cervicis

37

Taking right arm to left knee:

External
Internal

38

Origin of the quadratus lumborum:

Posterior iliac crest

39

Insertion of the quadratus lumborum:

Last rib and L1-L4 transverse processes

40

Action of the quadratus lumborum:

- Unilaterally
• Laterally flexes vertebral column to same side
• Laterally tilt (elevate) the pelvis
• Assist to extend the vertebral column
- Bilaterally
• Fix the last rib during forced inhalation and exhalation

41

Origin of the sternocleidomastoid:

- Sternal head
• Top of manubrium
- Clavicular head
• Medial ⅓ of the clavicle

42

Insertion of the sternocleidomastoid:

Mastoid process of the temporal bone and the lateral portion of superior nuchal line of occiput

43

Action of the sternocleidomastoid:

- Bilaterally:
• Flex the neck
• Assist to elevate the ribcage during inhalation
- Unilaterally:
• Rotate the head and neck to the opposite side
• Laterally flex the head and neck to the same side
