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.
