Correctly label the following anatomical features of the lymph node. – Correctly labeling the anatomical features of a lymph node is essential for understanding its structure and function within the lymphatic system. This guide provides a detailed overview of the capsule, cortex, paracortex, and medulla, along with their respective cell types and clinical significance.
Definition of a Lymph Node
Lymph nodes are small, bean-shaped organs that are part of the lymphatic system. They are located throughout the body, but are most commonly found in the neck, armpits, and groin. Lymph nodes filter lymph fluid, which is a clear liquid that contains white blood cells.
These white blood cells help to fight infection.
Anatomical Features of a Lymph Node
The capsule of a lymph node is a tough, fibrous outer layer that protects the node. The cortex is the outer region of the node, and it contains follicles, which are collections of white blood cells. The paracortex is the middle region of the node, and it contains T cells, which are a type of white blood cell that helps to fight infection.
The medulla is the inner region of the node, and it contains plasma cells, which are a type of white blood cell that produces antibodies.
Correctly Labeling Anatomical Features, Correctly label the following anatomical features of the lymph node.
| Label | Description |
|---|---|
| Capsule | Tough, fibrous outer layer that protects the node. |
| Cortex | Outer region of the node that contains follicles. |
| Paracortex | Middle region of the node that contains T cells. |
| Medulla | Inner region of the node that contains plasma cells. |
Clinical Significance of Lymph Node Anatomy
Understanding lymph node anatomy is important for medical diagnosis and treatment. Changes in lymph node structure or function can indicate disease. For example, enlarged lymph nodes may be a sign of infection or cancer. Lymph node biopsies are often used to diagnose diseases such as cancer.
FAQ Summary: Correctly Label The Following Anatomical Features Of The Lymph Node.
What is the function of the capsule in a lymph node?
The capsule provides structural support and protection to the lymph node.
What cell types are found in the paracortex?
The paracortex primarily contains T lymphocytes.
