Q

quadrangular space

A

-l = humerus
- m =long head of tricep brachii
- s = teres minor
-I = teres major
this is where axillary nerve and posterior circumflex humeral vein and artery pass through

Q

triangular interval

A

-s= teas major
-m=humerus /lateral head of tricep brachii
-l=long head of tricep brachi
radial nerve and profundus brachii artery are visible in the base of the triangular interval and they wind around the humerus in the radial groove

Q

triangular space

A
  • s=teres minor

Q

circumflex scapular artery

A
  • branch of the sub scapular artery that also originates from the third part of the axillary artery in the axilla
  • it leaves through the triangular space and into the infraspinous fossa, supplying teres major and minor as it forms anatomies with other arteries

Q

short head of bicep brachii

A
  • originates from the coracoid process and passes vertically down and unites with long head to form 1 single muscle belly wc inserts intoradias tuberosity vis bicep endon , it goes beneath the bicipital aponeurosis

Q

what compartment are bicep brachi and whats the function and IN? how do you test it’s tendon?

A
  • anteior
  • supinators at the radioulnar joint, flex the arm at the elbow joint and shoulder,
  • musculocutanous C5 6 7
  • tap the tendon with hammer and that should c flexion of elbow and supination

25
posterior compartment of arm
-tricpe brachi wc has 3 heads | ; 1 medial deep and 1lateral and 1 long head
26
tricep
all insert into the olecranon of the ulna and form a single tendon but originates in different places - M= is the deepest, shaft f humerus inferior to the radial groove - L= shaft superior to radial groove - Long head= infraglenoid tubercule of scapula
27
how do you test the tricpe
tap tendon just before the olecranon of the ulna b they are there
28
subacromial space
- space between the coraco-acromial arch (formed by coracoid process, acromion, coraco-acromial ligament ) - in this space is ; subacromial bursa /supeaspinatus tendon / joint capsule / long head of biceps
29
what happens in the subacromial space during abduction
- impingement (trapping) of these soft tissues leading to irritation and inflammation known as impingement syndomre
30
quadrangular space
-l = humerus - m =long head of tricep brachii - s = teres minor -I = teres major this is where axillary nerve and posterior circumflex humeral vein and artery pass through
31
triangular interval
-s= teas major -m=humerus /lateral head of tricep brachii -l=long head of tricep brachi radial nerve and profundus brachii artery are visible in the base of the triangular interval and they wind around the humerus in the radial groove
32
triangular space
- s=teres minor - I=teres major - L=long head of tricep brachi - NO NERVES just the circumflex scapular vessels enter the infrapinous fossa
33

38
where does brachial artery start
teres major below it, and it supplies forearm
39
where can you palpate the brachial pulse
cubital fossa,
40
cubital fossa
- between the medial and lateral epicondyle, - L =brachioradialis - M= pronator teres - contents are from lateral to medial; - tendon of bicep brachii , brachial artery, median nerve
41
bicep brachii
-short head and long head
42
short head of bicep brachii
- originates from the coracoid process and passes vertically down and unites with long head to form 1 single muscle belly wc inserts RADIAL tuberosity vis bicep endon , it goes beneath the bicipital aponeurosis
43
long head of bicep brachii
- originates at the supraglenoid tubercule , passes over the head and enters the intertubecular sulcus where held into position by the TRASNVERSE HUMERAL LIGAMENT and joins with the short head to from one single belly wc inserts on the radial tubersity via tendon of bicep brachii under the bicipital aponeurosis
44
transverse humeral ligament
holds the tendon of the long head of bicep brachii in place in the intertrubcular sulcus
45
bicipital aponeurosis
originates close to the musculotendious junction of the nicest and forms roof of curtail fossa
46

47
unscrew a cork action?
supinations | -anterior compartment (bicep and corocobrachialis )
48
pull out the cork screw

49

coracobrachilus | long and short head of bicep brachi
50

- impingement (trapping) of these soft tissues leading to irritation and inflammation known as impingement syndomre
57
why axilla
- brachial plexus - axillary nerve and vein - lymphatics
58
blood supply
R= brachiocephalic trunkL =aorta | - at lateral border fo first rib become the axillary artery
59
axillary nerve
- MOTOR; the deltoid and teres minr | - SESNSATION ;upper lateral cutaneous
60
radial groove
radial nerve and profudus brachi
