Axilla

Front 1

What is the axilla?

Back 1

The pyramidal space inferior to the glenohumeral joint and superior to the axillary fascia at the junction of the arm and thorax.

Front 2

What are the contents of the axilla?

Back 2

Blood vessels
Lymphatic vessels
Axillary lymph nodes
Axillary fat
Neurovascular structures

Front 3

Where does the axillary begin?

Back 3

At the lateral border of the 1st rib as the continuation of the subclavian artery and ends at the inferior border of the teres major. It passes posterior to the pectoralis minor into the arm and becomes the brachial artery when it passes the inferior border of the teres major, at which point it usually reached the humerus.

Front 6

First part of the axillary artery

Back 6

1st part is between the lateral border of the first rib and the medial border of the pectoralis minor.

Front 7

What does the axillary artery become and when?

Back 7

Brachial artery when it passes the inferior border of teres major, at which point it usually has reached the humerus.

Front 8

The Second part of the axillary artery

Back 8

Lies posterior to pectoralis minor and has two branches--the thoracoacromial and lateral thoracic arteries--which pass medial and lateral to the muscle, respectively.

Back 9

Extends from the lateral border of pectoralis minor to the inferior border of teres major and has three branches.

What forms the brachial plexus?

Back 15

The union of the anterior rami of the last four cervical (C5-C8) and the first thoracic (T1).
