As the lymph is entering the lymph node, there are many pathways that it may encounter, whether it be to subcapsular sinuses, trabecular sinuses, or medullary sinuses. The fibers are present in the lymph nodes in order to control and regulate the direction of the lymph through the node. Someone else said:
They wrap around the collagen so that they wont be exposed.

What cells cluster around the medullary sinuses?
The cells that cluster around the medullary sinuses in the lymph nodes are called reticular cells. These cells form a network of connective tissue, providing structural support for the lymph nodes. They also play a role in filtering lymph and facilitating immune responses.
What is the main role of lymph nodes in the bodys defence?
The lymph nodes store and make B cells which fight antigens (foreign substances in the body). To elaborate on and attempt to complete the answer, the lymph nodes are where the adaptive immune response begins and is maintained (contrasted with the innate immune response). Dendritic cells circulate throughout the body and pick up antigens (foreign substances in the body, e.g., those of microorganisms such as bacterial cell wall proteoglycans) associated with infected tissue and upon returning to the lymph nodes present them to T and B lymphocytes that pass through or may even reside at the node. The lymphocytes that now recognize the particular antigen proliferate and return to the main circulation and attack the associated microorganism. The adaptive immune response, as by proliferation of antigen specific lymphocytes, is also maintained at the lymph nodes after the infection is gone in case reinfection by the same microorganism occurs.
What is the location and role of the lymphatic system?
'Lymph' is not a 'tissue' per-se. The lymphatic system is a body system made up of lymph nodes and vessels which is an important part of your immune system. Lymph nodes produce a substance called 'lymph' that is carried throughout your body to help fight infections. Lymph nodes and vessels are located throughout your body--notably in your neck, thorax, underarm, and groin areas.
What is lymph nodes?
lymph node cancer is cancer in your lymph nodes they are all over your body..around you neck stomach legs arms you have lymph nodes all over
explain the role of the lymph node in the spread of cancer?
When a person has cancer, sometimes the cancer will metastize to other areas of the body. When cancer has metastizes, the lymph nodes can become involved due to the cancer spreading through the lymphatic fluid.
What is the role of macrophages in stimulating B lymphocytes?
some B lymphocytes are taken by macrophages to lymph nodes during the invasion the pathogen. The macrophages the exposes the pathogen's antigens to the B cells in the lymph nodes,The B cells with the matching receptor of the specific antigens respond by dividing repeatedly by mitosis, producing huge numbers over a few weeks.
Where is the inguinal node?
The inguinal nodes are located in the groin area, near the crease between the thigh and the lower abdomen. These nodes play a role in filtering lymphatic fluid from the lower extremities, genitals, and pelvic region.
If you have prostate cancer and the lymph nodes around the prostate are enlarged what does this mean?
The lymph system of the body is used for immune respones. It is a widely dispersed system that is also connected to the blood system. If a cancer anywhere in the body remains benign, that means it has remained in one organ only and not spread to any other organs. Unfortunately, once a cancer moves, or 'metastises' to the lymph nodes, this means the cancer is spreading and any number of organs could also become cancerous. Lymph nodes can carry cancer to the brain, lungs, breast, and bones just to name a few. Good luck...
What are the 2 major functions of the lymph nodes?
To return to the circulatory system the fluid that leaked out from the capillaries and that wasn't returned to the veins.To filter out any bacteria/viruses by leaving them in the lymph nodes, where an immune response is mounted and they're killed.
What the role of the lymph nodes in excretion?
their work is to remove foreign cells and pass their waste to the blood for excretion. by. V. Jaynar. HRCS
Which nerve network in the brainstem plays an important role in controlling arousal?
reticular formation
Do Lymph nodes accumulate cancer cells?
No - they are essential for protecting the body from infection and their function is to filter lymph fluid which circulates specialised white blood cells called lymphocytes throughout the body. It is these that are vital to the body's defences as they produce antibodies which play a part an important role in fighting infection.
