Chapter 8: The appendicular skeleton

Question 1

where is the only articulation between the upper limb and the thorax?

Answer 1

sternoclaviular joint- joint the clavicular notch of the sternum and the sternal end of the clavical

Question 2

which joint articulates to acromial end of the clavical and to the scapula?

Answer 2

the acromioclavicular joint

Question 3

how can you differenciate between the sternal and scalpular end?

Answer 3

• the sternal end is rounded

- the acromial end is flat

Question 4

what ligaments are attached to the clavical?

Answer 4

1. the costalclavicular ligament (from the 1st rib)
2. intracalvicular ligament (hold the two together over top of the manibrium)
3. sternoclavicular ligament (attches the clavical to the clavicular notch of the manibrum)

Question 5

where do broken collar bones usually occur?

Answer 5

the lateral (distal) third-closet to the shoulder

Question 6

Which part of the scapula forms the high point of the shoulder?

Answer 6

The acromion forms the high point of the shoulder.

Question 7

Which parts of the humerus articulate with the radius at the elbow? With the ulna at the elbow?

Answer 7

The radius articulates at the elbow with the capitulum and radial fossa of the humerus. The ulna articulates at the elbow with the trochlea, coronoid fossa, and olecranon fossa of the humerus.

Question 8

what is it that you hit when you “hit your funny bone”?

Answer 8

the ulnar nerve

Question 9

What part of the ulna is called the “elbow”?

Answer 9

The olecranon is the “elbow” part of the ulna.

Question 10

what are the three points where the radius and ulna atriculate?

Answer 10

1. the connective tissue of the interosseous membrane (joins the shafts)
2. the proximal radioulnar joint (the head of the radius attriculates with the ulna’s radial notch)
3. distal radialulnar joint (the head of the ulna articulates with the ulnar notch of the radius)

Question 11

the radius atriculates with which three bones of the wrist

Answer 11

1. lunate
2. scaphoid
3. triquetrum

Question 12

stop letting those people touch the cadaver hand

Answer 12

• scapoid
• lumate
• triquetrium
• pisiform
• trapizium
• trapaziod
• capitate
• hamate

Question 13

what are the 3 large components of the pelvis?

Answer 13

1. ilium
2. ishium
3. pubis

Question 14

what is the largest foramen in the skeleton?

Answer 14

obturator foramen

Question 15

what passes through the obturator foramen

Answer 15

• blood vessels and nerves

- amost completely closed off by obturator membrane

Question 16

what is the difference between a male and a female pelvis?

Answer 16

the pubic arch is much wider on a female

Question 17

tall centers never take short for corners

Answer 17

-talus
-calcaneus
-navicular
-third cuneiform
-second cuneiform
-first cuniform
cuboid

Question 18

what are the two arches of the foot?

Answer 18

• medial

- transverse

Question 19

how many bones are in each upper limb?

Answer 19

30

Question 20

how many bones of the lower limbs are there?

Answer 20

30

Question 21

what are the 3 major difference between the pelvic and shoulder girdles

Answer 21

1. The pectoral girdle does not articulate directly with the vertebral column; the pelvic girdle does via the sacroiliac joint.
2. The glenoid fossae are shallow and maximize movement; the acetabula are deep and allow less movement.
3. The pectoral girdle affords more mobility than strength; the pelvic girdle offers more strength than mobility.

Question 22

the tibula atriculates distaly with the?

Answer 22

talus

Question 23

The anatomical name for the socket into which the humerus fits is the:
