Flashcards in 2.1 Deep Back Deck (40):
1

Number of vertebrae and sections

33 vertebrae7 cervical12 thoracic5 lumbar5 sacral4 coccygeal

2

Period when cervical vertebrae becomes convex

4th to 5th month when the baby gains control of his head

3

Period when the lumbar area becomes convex

1 year when the baby begins to walk

4

Main mass of the bone; also the weight-bearing structure

Vertebral body

5

Identify and classify the intervening disks between vertebrae

Intervertebral discsSymphyses: fibrocartilaginous joints

6

Cartilage that covers the superior and inferior surfaces of the vertebral body

Hyaline cartilage

7

Process of the vertebrae which act on rotation, and maintains extended position of back

Transverse processes

8

Serve as shock absorbers

intervertebral discs

9

Parts of the intervertebral discs and corresponding description

Annulus fibrosus: multiple layers of fibrous cartilage in different directions like a tireNucleus pulposus: gel for shock absorbance

10

Where spinal nerves exit, blood supply enters and where venous structures enter and exit

Intervertebral foramen

11

Synovial joint formed by the inferior and superior articular processes; also, classify the joint

Zygopophysial joint; gliding joint

12

Smallest among 24 movable vertebrae

Cervical vertebrae

13

Describe the cervical vertebrae

Large and triangular foramenSmall and wide vertebral bodyNearly horizontal articulation of articular facets

14

Also known as the atlasWidest of the cervical vertebraeYES bone

C1 vertebrae

15

NO bone;Also known as the axis

C2 vertebrae

16

Describe the thoracic vertebrae

heart-shaped bodycircular and smaller vertebral foramenoverlapping spinous process which allows body to bend backaction is mainly rotationWith demifacet

17

Describe T12

one costal facetbody is cubical, so it's prone to fracture

18

Describe lumbar vertebrae

Massive body, kidney-shapedTriangular vertebral foramenLong and slender transverse processHatchet-shaped spinous processesFlexion, extension, and lateral flexion

19

processes of the lumbar vertebrae which provides attachment to multifidus and intertransversarii

Mamillary processess

20

Process of the lumbar vertebrae which provide attachment to intertransversarii muscles

Accessory processes

21

Largest of all movable vertbraeCarries the weight of the whole upper body

L5

22

Level where spinal cord ends

L1-L2

23

Ligament which encompasses almost hte entire anterior surface of the vertebral columnAttaches the base of the skull to sacral curvature

Anterior longitudinal ligament

24

Function of the anterior longitudinal ligament

Limits overextension

25

Ligament within the vertebral canal;Contains nociceptive endings

Posterior longitudinal ligament

26

Action of the posterior longitudinal ligament

Weakly resists hyperflexionHelps prevent herniation of the nucleus pulposus

27

Ligament which attaches one lamina to anotherHelps preserve normal curvatures of vertebral columnAssists with straightening of column after flexing

Ligamentum Flavum

28

Ligament from skull to C7

Ligamentum Nuchae

29

Action of the serratus posterior muscles

In respiration/labored breathing, and proprioception

30

Action of the errectors spinae (ILS)

Chief extensor of the vertebral column

31

Strongest cervical vertebrae

C2

32

Arterial supply of the cervical region

Occiptial, vertebral, and deep cervical arteries

33

Arterial supply of the thoracic region

Posterior intercostal

34

Arterial supply of the lumbar region

Subcostal and lumbar

35

Arterial supply of the sacral region

iliolumbar and lateral sacral artery

36

General nerve supply of the deep back

Posterior rami

37

Provide innervation to the ligamentum flavum

Recurrent meningeal nerve

38

Lymphatic drainage of the skin of the neck

Cervical nodes

39

Lymphatic drainage above the ilac crests

Axillary nodes

40

Lymphatic drainage of the structures below the level of the iliac crests

Superficial inguinal nodes
