1

What are the 2 joints the clavicle is involved in?

-Sternoclavicular joint
-Acromioclavicular joint

2

What 2 ligaments are associated with the clavicle?

-Costoclavicular ligament
-Coracoclavicular ligament

3

What classification system is used in dislocations of the Ac joint?

Tossy

4

What tests can be used to determine the degree of AC dislocation?

-10Kg test
-Piano key test

5

What is the result of embryonic limb rotation?

-The anterior surface of the developing lower limb becomes the plantar aspect of he foot
-The ventral flexor muscle masses are located largely posterior to the knee, as opposed to anterior to the elbow

6

What movements can occur in the upper limb?

-Elevation and depression
-Abduction and adduction
-Flexion and extension
-Pronation and supination

7

What does the human's ability to grasp the hands in varied locations rely on?

The composite mobility of all of the joints involved

8

Where in the lower limb is the only joint which allows rotational movements?

Hip

9

Where in the lower limb is there no significant movements?

Tibio-fibula joints

10

What in the lower limb is equivalent to the axilla?

Femoral triangle

11

Why is the femoral triangle not against the trunk?

Due to bipedal stance and limb rotation

12

What are the common contents of the femoral triangle and the axilla?

-A stem artery enters and gives off a deep branch
-Accompanying major vein receives a superficial tributary
-Nerve(s) enter

13

What is responsible for almost all of the innervation of the upper limb?

Brachial plexus

14

Where does the brachial plexus enter the arm?

Enters into the axilla at the lateral border o the 1st rib

15

What is the major plexus of the lower limb?

Lumbosacral plexus

16

What are the 3 major branches of the lumbosacral plexus?

-Obturator nerve
-Sciatic nerve
-Femoral nerve

17

How does the median nerve enter the hand?

Through the carpal tunnel

18

How do the ulna artery and nerve enter the hand?

Superficially

19

How does the radial artery enter the hand?

Through the 1st web space

20

How do the posterior tibial artery and nerve enter the foot?

Enter the sole of the foot posterior to the medial malleolus

21

What does the posterior tibial artery give rise to?

The plantar arch via lateral and medial plantar arteries
