The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb. They are divided in ...
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
A lymph node is divided into compartments called nodules (or lobules), each consisting of a region of cortex with combined follicle B cells, a paracortex of T cells, and a part of the nodule in the medulla. [17] The substance of a lymph node is divided into the outer cortex and the inner medulla. [4]
Humans usually have four parathyroid glands, located on the back of the thyroid gland in variable locations. The parathyroid gland produces and secretes parathyroid hormone in response to low blood calcium, which plays a key role in regulating the amount of calcium in the blood and within the bones.

An anterior or pectoral group consists of four or five glands along the lower border of the Pectoralis minor, in relation with the lateral thoracic artery.. Their afferents drain the skin and muscles of the anterior and lateral thoracic walls, and the central and lateral parts of the mamma; their efferents pass partly to the central and partly to the subclavicular groups of axillary glands.
A lymph node is an organized collection of lymphoid tissue, through which the lymph passes on its way back to the blood. Lymph nodes are located at intervals along the lymphatic system. Several afferent lymph vessels bring in lymph, which percolates through the substance of the lymph node, and is then drained out by an efferent lymph vessel.
The term "axilla" refers to the armpit or underarm section of the body. [2] The axillary dissection procedure is commonly used in treating the underarm portion of women who are dealing with breast cancer. [3] The lymph nodes located in the axilla area that are affected by breast cancer are called the guardian or sentinel lymph nodes.
