axilla Flashcards
what does the axilla contain
axillary arteries and veins, the brachial plexus and axiallary lymph nodes.
brachiosephalic trunk divides into what
the right subclavian and the right carotid arteries
whats the path of the subclavian veins
passing under the lower boarder of the rib to become the axillary artery
what does the axillary artery pass around to make it to the brachial artery
it goes above the pectoralis major, under the pectoralis minor then to the lower boarder of the teres major.
where does the axillary artery become the brachial artery
once it passes by the teres major muscle
what forms the brachial plexus
the ventral rami of C5, C6, C7, C8, T1
the cords of the brachial plexus are named according to what
where they lie in relation to the brachial artery, so medial, lateral and posterior cords
what nerve supplies the serratus anterior and whats its supply
the long thoracic nerve from the C5, C6 roots
what nerve supplies the latismus dorsi and whats its supply
the thoracodorsal nerve comes off of the dorsal cord
nerve supply of the musculocutaneous nerve
C5 C6 C7
whats the nerve supply of the axilalry nerve
C5, C6
whats the nerve supply of the medial nerve
C5, C6, C7, C8, T1
whats the nerve supply of the radial nerve
C5, C6, C7, c8, T1
whats the nerve supply of the ulnar nerve
C8, T1 - can be C7 at times tho
what makes up the apex of the axillary space
anteriorly the clavicle, medially the first rib posteriorly the superior boarder of the scapula
what makes up the base of the axillary space
skin, subcutaneous tissue and axillary fascia extending from the arm to the thoracic wall
whats the anterior wall of the axillary space
pectoralis major and pectoralis minor, clavicopectoralis fascia
what makes the posterior wall of the axillary space
subscapularis, latissimus dorsi, teres major and the long head of triceps brachii
what makes the lateral wall of the axillary space
the intertubercular groove of the humerus
what makes the medial wall of the axillary space
the serratus anterior muscles
