Take the Quiz

1 Lymph is carried towards an lymph node by:

	afferent lymph vessels
	efferent lymph vessels

2 The most abundant white blood cells as a percentage of all cells in normal circulation are the

	lymphocytes
	basophils
	monocytes
	eosinophils
	neutrophils

3 Why does this lymphocyte shown in this EM contain lots of RER?

	Because its a cytotoxic T lymphocyte
	Because its a monocyte
	Because its a macrophage
	Because its a Plasma cell
	Because its a B lymphocyte

4 In normal peripheral blood which the most abundant lymphocyte cell type?

	T cells
	B cells

5 Reticular fibres are composed of type III collagen and secreted by reticular cells. Which of the following statements are correct about reticular fibres?

	Reticular fibres are very delicate and form fine networks instead of thick bundles.
	Reticular fibres give support to individual cells.
	Reticular fibres stain black in silver stained preparations.
	Reticular fibres form open meshwork's allowing the exchange of substances and cell movement.

6
Which of the following best describes the spleen histology and feature shown in the above histological image?

	Spleen white pulp germinal centre
	Spleen red pulp splenic sinuses
	Spleen reticular fibres and sinuses
	Its not spleen at all, but a lymph node follicle.

7 Which of the following sequences best describes the pathway of lymph fluid through a lymph node

	Subcapsular sinus -> Paratrabecular sinus -> Medullary sinus -> Efferent vessel
	Subcapsular sinus -> Paratrabecular sinus -> Medullary sinus -> Afferent vessel
	Subcapsular sinus -> High endothelial venule -> Medullary sinus -> Thoracic duct
	Subcapsular sinus -> Medullary sinus -> Paratrabecular sinus -> Hilum vessel

8
Which of the following descriptions best describes the function of High endothelial venules?

	Act as a site for the distribution of macrophages in lymph nodes
	Drain lymph fluid from secondary lymph organs
	Specialised blood vessels in the spleen
	Specialised site for lymphocyte extravasation
