lymphatic system Flashcards
(47 cards)
Hassall´s corpuscles are found in the cortex of the Thymus
f
Hassall´s corpuscles are located in the medulla of the Thymus
t
Hassall´s corpuscles are located in the medulla of the Thymus
t
Epithelial reticular cells form a supporting network of developing (=immature) Tlymphocytes in the Cortex of Th
t
Epithelial reticular cells of thymus together with the endothelium of cortical capillaries
form a blood-thymus barrier
t
Reticuloepithelial cells form the inner stroma of thymus
t
Fibrous septa divide the parenchyma of thymus into incomplete lobules
t
The medulla of Thymus does NOT contain any mature T-lymphocytes
f
The medulla of Thymus appears lighter than cortex using HE-staining
t
Thymus contains many lymphoid nodules
f
Medulla of lymph node contains also the lymphoid nodules
f
Medulla of Lymph node consists of sinusoids and cords of Billroth
f
Medullary cords of the lymph node are composed of the reticular epithelium and
lymphocytes
f
The cortex of lymph nodes contain mainly structures with a predominance of Blymphocytes
t
The cortex of lymph nodes contains mainly lymph nodules and reticular ligament
t
Both cortex and paracortex of the lymph node are composed of lymphoid nodules
containing predominantly B-Lymphocytes
f
T-lymphocytes and no B-lymphocytes are found in the paracortex of Lymph node
T
A lymph node paracortex comprises T-cells, macrophages and dendritic cells
T
Paracortex of lymph node contains high endothelial venules (HEV) and is T-dependent
zone
T
Lymph race flows inside the lymph node through the system of cortical and medullar
sinuses
T
Lymph flows inside the lymph node through a system of cortical and medullary sinuses
T
The lymph node is covered by a capsule containing predominantly type I collagen
T
The lymph node stroma is formed by the reticulum epithelium
f
Lymph nodules in all secondary lymphatic organs are also referred to as Malpighi´s bodies
