Axilla Pyramidal space between side of the chest and upper part of the arm Apex  A passageway for blood vessels, lymph vessels and nerves between root of the neck and the upper limb 1R Lateral wall Has:  • Apex • Base • 4 walls Dr. Maher Hadidi Spring 2019 Dr. Maher Hadidi, University of Jordan 2

Axilla Apex  At root of the neck. Borders:  Anterior Clavicle  Posterior Scapula  Medial 1st Rib Dr. Maher Hadidi Superior view Spring 2019 Dr. Maher Hadidi, University of Jordan 3

Axilla Base  Form by skin, superficial fascia and deep fascia .  It contains numerous sweat glands and coarse hair. Dr. Maher Hadidi Base of axilla Spring 2019 Dr. Maher Hadidi, University of Jordan 4

Axillary artery Continuation of the subclavian artery.  • Begins at the outer border of the first rib. • Ends at lower border of T. major. • Continue as brachial artery. Crossed by pectoralis minor, dividing it  into 3 parts. Each part gives branches according to its  number. Located inside axillary sheath and  related directly to cords of brachial plexus throughout its course. Spring 2019 Dr. Maher Hadidi, University of Jordan 8

Arteriogram of the Axillary & Brachial arteries Spring 2019 Dr. Maher Hadidi, University of Jordan 10

Superficial Veins Both Upper and Lower limb are similar in  having two superficial veins to drain their superficial structures. In the upper limb:  •Cephalic vein Lateral •Basilic vein Medial Both ends into the axillary vein.  Both connected by the median cubital vein  anterior to elbow joint. •This vein commonly used to give fluids or to Dr. Maher Hadidi obtain blood sample. Spring 2019 Dr. Maher Hadidi, University of Jordan 11

Axillary Vein  Begins by the union of the basilic vein& veins of the brachial artery at lower border of teres major.  Passes upward medial to axillary a.  Ends At outer border of the 1st rib to continue as the subclavian v.  Receives cephalic vein at its end.
