Front 13

What are the 5 major regions of the vertebral column

Back 13

cervical, thoracic, lumbar, sacrum, and coccygeal regions

Front 14

In which 2 of these regions is the vertebral column concave posteriorly

Back 14

cervical and lumbar

Front 15

Besides the spinal curvatures, which skeletal elements help to make the vertebral column flexible

Back 15

fibrocratilage discs.

Front 16

What is the normal number of cervical vertebrae? Of thoracic vertebrae?

Back 16

Cervical: 7

Thoracic: 12

Front 17

How would a complete fracture of the dens affect the mobility of the vertebral column

Back 17

the dens is the axis on which the atlas rotates; if it is broken then movement of the atlas would be less controlled

Front 18

How can you distinguish a lumbar vertebra from a thoracic vertebra

Back 18

Lumbar: heavier and its massive body is kidney shaped; spinous proceses are short and project directly back

Thoracic: body is generally heart shaped, the spinous process is long, sharp, and points downward, and its transverse processes have facets for articulating with the ribs

Front 19

How does a true rib differ from a false rib

Back 19

a true rib connects to the sternum with its own costal cartilage; a false rib connects to the sternum via costal cartilages of other ribs or not at all

Front 20

What is the sternal angle and what is its clinical importance

Back 20

the sternal angle is a ridge across the front of the sternum where the manubrium joins the sternal body. It acts as a hinge allowing the sternum to swing anteriorly when we inhale. It is also a handy tool for counting the ribs

Front 21

Besides the ribs and sternum, there is a third group of bones making up the thoracic cage; what is it

Back 21

the thoracic vertebrae also contribute the thoracic cage

Front 22

What two bones also construct the pectoral girdle

Back 22

scapula and clavicle

Front 23

Where is the single point of attachment of the pectoral girdle to the axial skeleton

Back 23

the medial ends of the clavicle connects it to the sternal manubrium

Front 24

What is the major shortcoming of the flexibility allowed by the shoulder joint

Back 24

the shortcoming is that it is easily dislocated

Front 25

Which bones play the major role in forming the elbow joint

Back 25

ulna and humerus

Front 26

Which bones of the upper limb have a styloid process

Back 26

ulna and radius have a styloid process distally

Front 27

Where are carpals found and what type of bone are they

Back 27

proximal region of the hand; short bones

Front 28

The ilium and pubis help to form that os coxae. What other bone is involved in forming the os coxae

Back 28

ischium

Front 29

The pelvic girdle is a heavy, strong girdle. How does its structure reflect its function

Back 29

it receives the weight of the upper body and distributes it to the lower body

Front 30

Which of the following terms or phrases refer to the female pelvis

wider, shorter sacrum; cavity narrow and deep; narrow heart shaped inlet; more movable coccyx; long ischial spines

Back 30

wider shorter sacrum; more movable coccyx

Front 31

What lower limb bone is the second largest bone in the body

Back 31

tibia

Front 32

Where is the medial malleolus located

Back 32

distalmost medial aspect of the tibia

Front 33

Which of the following sites is not a site of muscle attachment

greater trochanter; lesser trochanter; gluteal tuberosity; lateral condyle

Back 33

lateral condyles (they are articular surfaes)

Front 34

Besides supporting our weight, what is a major function of the arches of the foot

Back 34

because of their springiness they save energy during locomotion
