Study Notes
Lymphatic Components and Pathways
- Lymphatic pathway comprises vessels, nodes, and organs responsible for lymph transport and immune response.
- Pathway initiates at lymphatic capillaries, continues to lymphatic vessels, nodes, and drains into larger ducts.
- Major structures include the thoracic duct and right lymphatic duct, which return lymph to the bloodstream.
Photomicrographs and Structures
- Photomicrographs used to study details of lymphatic tissues and nodes such as the spleen, tonsils, and lymph nodes.
- Visual aids help identify structures like the capsule of lymph nodes, medullary cords, and cysterna chyli.
- Labeling exercises aid in memorizing anatomical features and functions of lymphatic organs.
Functional Structures and Terms
- Cysterna chyli: Collects lymph from the intestinal trunk, aiding in fat absorption.
- Inguinal nodes: Located in the groin area, filtering lymph from the lower limbs and pelvic region.
- Medullary cords of lymph node: Supports lymphocyte production and function within lymph nodes.
- Mucosa of ileum: Contains lymphoid tissue important for immune responses in the intestinal tract.
- Peyer’s patches: Aggregates of lymphoid tissue in the ileum facilitating immune surveillance.
The Spleen and Thymus
- Spleen serves as a blood filter, recycling iron from hemoglobin and housing immune cells.
- Thymus plays a role in T lymphocyte maturation, critical for adaptive immunity.
ELISA and Its Applications
- ELISA stands for Enzyme-Linked Immunoassay, a technique for detecting and quantifying proteins or antibodies.
- The specific substrate for horseradish peroxidase (HRP) is hydrogen peroxide, producing a distinguishable blue or yellow color change.
- Quantification in ELISA relies on the intensity of the color change, indicating the presence and concentration of analytes.
Regional Labeling of Lymph Nodes
- Lymph nodes classified based on anatomical regions to help locate and study their specific functions and importance within the lymphatic system.
