Lymph node histology

Histological staining of lymph node samples are strongly influenced by the amount of antigen the cells of the lymph node are exposed to. Additionally, the number of cells within the node as well as the distinct separation of the cords is also influenced by antigenic exposure. As a result, th The nodes are covered by a capsule of dense connective tissue, and have capsular extensions, of connective tissue, called the trabeculae, which provide support for blood vessels entering into the nodes. Lymph, containing micro-organisms, soluble antigens, antigen presenting cells, and a few B-cells, enters the lymph node via afferent lymphatic vessels which enter the subcapsular sinus

Lymph nodes are traditionally regarded as having three compartments, the cortex, paracortex and medulla. B and T cells home to separate areas within these compartments, interact with antigen presenting cells, and undergo clonal expansion. This paper provides structural and functional details about how the lymph node brings lymphocytes and antigen presenting cells together. The concept of the lymphoid lobule as the basic functional and anatomic unit of the lymph node is developed and utilized. Lymph nodes are organized to detect and inactivate foreign antigens present in lymph fluid that drains skin, GI tract and respiratory tract, the major organs in contact with the environmen Lymph nodes function as filters of tissues and tissue fluids and are sites of origin and production of lymphocytes for normal physiological functions. As part of this normal function, they react. Lymph nodes are essentially information marketplaces where antigen presenting cells, the body's scouts, come to display information they have gathered about antigens they have encountered in the field and patrolling lymphocytes come to look for evidence that their specific antigen has entered the body. The lobule provides the infrastructure for the marketplace and its activities. The reticular meshwork and its channels and interstices provide spaces for APCs and lymphocytes to. •lymph arriving at a lymph node contains antigens free in solution or bound to antibodies or complement, still on microorganisms, or already internalized and transported by APCs. •If draining from an infected or inflamed region, lymph may also contain microorganisms and cytokines. Antigens not yet phagocytosed will be internalized by APCs in the lymph nodes an

The medulla of the lymph node consists of medullary sinuses, through which lymph percolates, and medullary cords, composed of B lymphocytes, macrophages, reticular cells and plasma cells. Subcapsular sinus >. Afferent lymph vessels penetrate the node at its convex surface, where lymph enters the subcapsular sinus Lymph node: cortex. A capsule and the underlying subcapsular sinus surround the outer cortical zone. Lymph, together with the lymph-borne immune cells, first enters the subcapsular sinus via afferent lymphatic vessels This layer contains arterioles and venules that supply the lymph node. The lymph node is divided into an outer cortex and an inner medulla. Histological staining of the node reveals that the cortex stains darker than the medulla with hematoxylin and eosin (H&E) due to its higher cell content lymph node histology images. 267 lymph node histology stock photos, vectors, and illustrations are available royalty-free.
