GENERAL HISTOLOGY

Detailed explanation-1: -Central lymph nodes appear in the base of the axilla. They receive lymph from the anterior, posterior, and lateral groups, and drain to the apical lymph nodes.

Detailed explanation-2: -They are about 1cm in size and are arranged into five groups: subscapular axillary (posterior), apical (medial or subclavicular), pectoral axillary (anterior), brachial (lateral), and central lymph nodes. The subscapular axillary lymph nodes are located on the lower part of the armpit’s posterior (rear) wall.

Detailed explanation-3: -The axillary lymph nodes are a collection of grouped lymph nodes found in the axillary region of the upper limb. The axillary region is commonly referred to as the ‘armpit’, although it is a three-dimensional space bound inferiorly by skin and anteriorly by the clavicle.
