What are the 2 joints the clavicle is involved in?
What 2 ligaments are associated with the clavicle?
What classification system is used in dislocations of the Ac joint?
What tests can be used to determine the degree of AC dislocation?
-Piano key test
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
What movements can occur in the upper limb?
-Elevation and depression
-Abduction and adduction
-Flexion and extension
-Pronation and supination
What does the human's ability to grasp the hands in varied locations rely on?
The composite mobility of all of the joints involved
Where in the lower limb is the only joint which allows rotational movements?
Where in the lower limb is there no significant movements?
What in the lower limb is equivalent to the axilla?
Why is the femoral triangle not against the trunk?
Due to bipedal stance and limb rotation
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
What is responsible for almost all of the innervation of the upper limb?
Where does the brachial plexus enter the arm?
Enters into the axilla at the lateral border o the 1st rib
What is the major plexus of the lower limb?
What are the 3 major branches of the lumbosacral plexus?
How does the median nerve enter the hand?
Through the carpal tunnel
How do the ulna artery and nerve enter the hand?
How does the radial artery enter the hand?
Through the 1st web space
How do the posterior tibial artery and nerve enter the foot?
Enter the sole of the foot posterior to the medial malleolus
