whats the spaces viewed from the back
triangular interval

quadrangular space
whats the spaces viewed from the back
triangular interval
triangular space
quadrangular space
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
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
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
circumflex scapular artery
- 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
how is axillary artery formed
whensubclvian artery crosses the lateral border of the first rib to enter the axillae
axilla
- L=thoracic wall and serratus anterior
-S = lateral margin of 1st rib
-L= humerus
-F=armpit skin
A= pectoralis major
-Pos=LAst/ters/subscap/long head
subcapular arter
originates third part of axillary artery and it anastoems with transverse cervical artery and supescapular artery
transverse cervical artery
from the subscapular artery
where does brachial artery start
teres major below it, and it supplies forearm
where can you palpate the brachial pulse
cubital fossa,
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
bicep brachii
-short head and long head
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 intoradias tuberosity vis bicep endon , it goes beneath the bicipital aponeurosis
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
transverse humeral ligament
holds the tendon of the long head of bicep brachii in place in the intertrubcular sulcus
bicipital aponeurosis
originates close to the musculotendious junction of the nicest and forms roof of curtail fossa
what compartment are bicep brachi and whats the function and IN? how do you test it’s tendon?
- 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
unscrew a cork action?
supinations
-anterior compartment (bicep and corocobrachialis )
pull out the cork screw
flexion
anterior compartment
anterior compartemtn
coracobrachilus
long and short head of bicep brachi
coracobrachiuls
O from coracoid process and inserts into medial side humeral shaft
f = olex the arm at the shoulder and weak abductor
innervated by msuculocutanous C. 6 7
brachialis
forms the floor of cubital fossa
- deep to the bicep brachii
- O = anterior distal shaft and inserts intent he coracoid
- f = fletcher forarm
- In= muschulocutanos
