The head of thehumerus and of the scapula can be felt at the upper andposterior part of the axilla, the second rib on the innerside, and the coracoid process in front. The head of thehumerus looks in the same direction as the internalcondyle of the humerus. The inner wall of the axilla isformed by the upper part of the lateral wall of the thorax,which is here clothed by the serrations of the serratusmagnus muscle. The axillary lymphatic glands are arranged in three maingroups, all converging towards the apex of the axilla : (a) The pectoral set, running upwards and outwardsunder cover of the outer border of the pectoral musclesand draining the anterior and lateral aspects of the chest-wall and the abdomen above the level of the umbilicus. (b) The subscapular set, running upwards along theaxillarv border of the subscapularis muscle, and draining

Immediately below the external con- ^ ^- dyle the head of the radius is felt lying in the valley behind the supinator longus (Holden). Thehumero-radial articulation is transverse, but the humero-ulnar articulation slopes obliquely downwards andinwards, and consequently, whilst the exter
