The cortex of a lymph node is the outer portion of the node, underneath the capsule and the subcapsular sinus. [17] It has an outer part and a deeper part known as the paracortex. [17] The outer cortex consists of groups of mainly inactivated B cells called follicles. [5] When activated, these may develop into what is called a germinal centre. [5]
A lymph node showing afferent and efferent lymphatic vessels Regional lymph nodes. 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.
The lobes consist of an outer cortex rich with cells and an inner less dense medulla. [4] The lobes are divided into smaller lobules 0.5-2 mm diameter, between which extrude radiating insertions from the capsule along septa. [1] The cortex is mainly made up of thymocytes and epithelial cells. [3]
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 small, capsulated lymphoid organ that is present along the lymphatic system. It is composed of cortex and medulla. The cortex is also divided into outer cortex and inner cortex (also known as the paracortex). The outer cortex is composed of follicles of B cells so that it is called the B-cell zone.
The Bahamas has “firmly rejected” President-election Donald Trump's proposal to fly deported immigrants out of the U.S. and into the small island nation about 100 miles southeast of Florida ...
Germinal centers are initiated in the B cell follicle of the lymph node. Following activation of naive B cells in the lymph node follicles, the B cells migrate to the interfollicular areas so that they can interact with T cells. When the B and T cells interact, the antigen-specific T cell receptors bind the antigen + MHC presented by the B cells.
