GENERAL HISTOLOGY

Detailed explanation-1: -Lateral (humeral) lymph nodes are over the lateral wall of the axilla. They receive lymph from the arm and drain into the central, apical, and deep cervical nodes. Central lymph nodes appear in the base of the axilla.

Detailed explanation-2: -Every woman has a different number of lymph nodes under her arm-some may only have five nodes and others may have more than 30.

Detailed explanation-3: -It runs from the superior aspect of the cisterna chyli, a lymph sac at the L2 vertebral level, to the lower cervical spine. From the cisterna chyli, the duct continues superiorly, running between the aorta and the azygous vein and anterior to the vertebral column.

Detailed explanation-4: -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.
