|
What are the three subcatagories you memorized for the sub cubital fossa arteries?
|
1. collateral (4)- median, radial, superior ulnar, inferior ulnar
2. recurrents (3)- radial, anterior ulnar, posterior ulnar 3. interosseus (4)- common, recurrent, posterior, anterior BIATCH! |
|
|
What are the muscles of the anterior compartment of the brachium... role? Main artery?
|
The flexors, innervation musculocutaneous nerve
3 types. 1. biceps brachii- long, short head 2. brachialis 3. coracobrachialis |
|
|
What three muscles attach to corocoid process of scapula?
|
1. pectoralis minor
2. biceps short head 3. coracobrachialis |
|
|
What muscle does musculocutaneous pierce after it exits brachial plexus?
|
1. coracobrachialis
|
|
|
What is the major flexor of the arm/elbow joint? Why?
|
brachialis, due to fixed attachments on the ulna (which does not move when your arm moves)
therefore it able to use full width |
|
|
What are the functions of each of the posterior compartment muscles and names...(of humerus)
|
1. triceps brachii
a. long head b. medial head b. lateral head 2. anconeus- stabilizes the lateral elbow joint, abducts ulna during protonation |
|
|
Where does the anconeous originate and insert?
|
proximal- lateral epicondyle of humerus
distal- lateral surface of olecrannon |
|
|
what is the greatest extensor of the arm?
What happens when there is radial nerve damage and why? |
triceps
Radial nerve damage will not allow the triceps to keep biceps from flexing. Wrists go into flexion (wrist drop) |
|
|
What is main venous communication from medial to lateral in arm?
What is it used for in clinics? |
median cubital vein... used for taking blood
|
|
|
What are the boundaries of the cubital fossa?
|
1. lateral- brachioradialis
2. medial- pronator teres 3. superior- imaginary line between the two epicondyle 4. roof- bicipital aponeurosis 5. floor- supinator and brachialis |
|
|
what is the most medial structure in the cubital fossa?
|
medial nerve
|
|
|
What two things makes the biceps more powerful during supination?
|
because tendon of biceps brachii and bicipital aponeurosis are taught
|
|
|
If asked to name medial to lateral the medial nerve the biceps and brachial artery what would you say?
|
Medial nerve, brachial artery, and biceps...
|
|
|
Compare the bicipital aponeurosis' position within the cubital fossa to bracial artery and median nerve...
|
superficial to both
|
|
|
Compare the median cubital vein's position to bicipital aponeurosis
|
superificial
|
|
|
compare the median nerve's position in cubital fossa to the brachial artery
What two muscles does the musculocutaneous nerve lie? |
medial
biceps brachii and brachialis |
|
|
What is positional relationship between radial nerve, brachioradialis, and brachialis
|
radial nerve is in between
|
|
|
What is relationship between superficial radial nerve and brachioradialis?
|
underneath brachioradialis
|
|
|
What is relationship between supinator and deep radial nerve?
|
supinator is penetrated by deep radial nerve
|
|
Label all!
|
a. superior ulnar collateral a.
b. inferior ulnar collateral a. c. middle collateral a. d. radial collateral a. e. deep brachial a. (profundi branchi) f. brachial artery g. anterior ulnar recurrent a. h. posterior ulnar recurrent a. 1. recurrent interosseus a 2. common interosseus a. 3. anterior interosseus a. 4. posterior interosseus a. 5. ulnar a. 6. radial recurrent a. 7. ulnar a. 8. radial a. |
