Question 24

Describe the radial nerve

Answer 24

The radial nerve originates from the brachial plexus, it wraps posteriorly around the mid-shaft humerus, passes interior to the lateral condyle, it travels postero laterally in the forearm. It is also the largest nerve in the upper extremity

Question 25

Describe the ulnar nerve

Answer 25

It originates from the brachial plexus, it travels along the medial humorous, passes posterior to the medial epicondyle, travels along antero medial forearm to the medial corner of hand.

Question 26

Describe the median nerve

Answer 26

It originates from the brachial plexus, it travels along the antero medial humerus (between the ulnar nerve and humorous), it travels interior to the medial epicondyle and travels along the interior form to the base of the middle of the Palm.

Question 27

Describe the sciatic nerve

Answer 27

It originates from the lumbosacral plexus, it travels out of the pelvis between the anterior sacrum and posterior ischium. It travels along the postero-medial femur. Lastly it’s splits just above the knee into the common fibular nerve and the tibial nerve.

Question 28

Describe the common fibular nerve

Answer 28

It travels lateral to the knee, around the fibular neck, and it travels down the interior fibula and ends in the dorsal surface of foot

Question 29

Describe the tibial nerve

Answer 29

It travels across the posterior knee and posterior tibia. Travels medial to the ankle joints to the planter surface of foot.

Question 30

Describe the femoral nerve

Answer 30

Question 34

What does pulmonary mean in terms of veins and arteries

Answer 34
