Lymph Node Labeling Quiz

Lymph Node Components

• Afferent Lymphatic Vessels:

  • Transport lymph fluid from peripheral tissues into the lymph nodes.
  • Multiple afferent vessels can enter a single lymph node.

• Efferent Lymphatic Vessels:

  • Carry lymph fluid away from lymph nodes to the circulatory system.
  • Typically fewer in number compared to afferent vessels.

• Cortex:

  • The outer region of the lymph node, containing lymphatic follicles.
  • Primarily involved in the filtration of lymph and early immune responses.

• Follicle:

  • A structure within the cortex, consisting of a dense accumulation of B cells.
  • Sites of antibody production and maturation of B lymphocytes.

• Germinal Center in Follicle:

  • Located within the follicle, it is where B cells proliferate and differentiate.
  • Plays a critical role in the development of high-affinity antibodies.

• Trabecula:

  • Extensions of the capsule that partition the lymph node into compartments.
  • Provide structural support and facilitate the flow of lymph.

• Capsule:

  • The outer fibrous layer that encases the lymph node.
  • Protects the internal structures and helps maintain the shape of the lymph node.

Test your knowledge on the anatomy of lymph nodes with this labeling quiz. Each card features important terms like afferent and efferent vessels, cortex, and germinal centers. It's a great way to reinforce your understanding and retention of lymphatic system structures.
