34

name the bones of the spine and their sections

consists of 26 bones split in 5 regions

7 cervical

12 thoracic

5 lumbar

1 sacral

1 coccygeal 

35

kyphosis

unusual curvature of the upper thoracic area, causing a hunchback

36

lordosis

an abnormal curve of the lumbar spine, causing a swayback condition

37

scoliosis

an abnormal lateral curve of the spine

38

functions of the vertebral column (5)

1. supports the weight of the head and trunk

2. protects the spinal cord

3. allows spinal nerves to exit the spindal cord

4. provides a site for muscle attavhment

5. permits movement of the head and trunk

39

cervical spine

c1-c7

transverse foramen

bifid spinous process (except c7)

c1 (atlas) articulates with bas of skull

c7 articulates with T1

40

C1 (Atlas)

no body and spinous process

2 arches on the anterior and the posterior

articulates with base of the skull and with dens of C2

41

C2 Axis

has a dens that articulates with C1

42

Thoracic region 

T1- T12

long slender spinous process (some slant)

long slender transverse process

heart shaped bodies

facets for rib articulation

T1 art. with C7

T12 art, with L1

43

Lumbar region

L1-L5

thickest vertabrae

kidney shaped body

short, stubby processes

L1 art. with T12

L5 art. with sacrum

 

44

sacrum

5 sacral vertebrae are fused to make it

45

thoracic cage

consists of true ribs (1-7) which attach to the sternum, and false ribs (8-12) which do not. 8-10 attach via a common cartilage. 11-12 are floating ribs.

46

xiphoid process

found at the bottom of the sternum

47

clavicle

the collar bone

48

the pectoral girdle

4 bones : LR scapula, and LR clavicle

49

scapula

known as the shoulder blade

50

acromion process

point where the scapula art. with the clavicle

51

coracoid process

provides attachment of the arm and chest muscles

52

glenoid cavity

where the head or the humerus art. to the scapula

53

humerus

the arm bone that connects to the scapula and the forearm bones

54

Ulna

a bone in the forearm that is found on the medial side (anatomical position)

55

radius

a bone in the forearm that is found on the lateral side (anatomical position)

56
