Nov 1, 2013 · Medullary cords: Found in hilar region between the sinuses, composed mostly of small B and T lymphocytes, plasmacytoid lymphocytes, plasmablasts and plasma cells Sinuses:
Lymphatic System | histology - University of Michigan
The lymph node is composed of follicles surrounding medullary cords and sinuses. A feature that is characteristic of the lymph node is the post capillary, high endothelial venule. You can occasionally see lymphocytes migrating from the blood into the lymph node if you examine the walls of these vessels.
Lymph nodes: Histology - Kenhub
Aug 3, 2023 · Medulla. The deepest layer of the lymph node is the medulla. It is subdivided functionally and histologically into two other regions; which are the medullary cords and sinuses. The cords are populated by plasma cells, as well as B – cells and T – cells. The cells are arranged in cord-like projections extending centrally from the paracortex.

The medulla is the central region of the node in which many small lymphatic vessels are evident. The walls of these lymphatic vessels are formed by an open meshwork of reticular cells.
Lymph Nodes | Lymphoid System - Histology Guide
Medullary Cords - contain antibody secreting plasma cells, macrophages, and B lymphocytes. Medullary Sinuses - intervening spaces in which lymph flows before exiting the node via efferent lymphatic vessels.
Normal Structure, Function, and Histology of Lymph Nodes
A single afferent lymphatic vessel delivers a constant stream of lymph to the sub-capsular sinus over each lobule. Lymph spreads through the subcapsular sinus over the lobule’s apex, flows down the sides of the lobule through transverse sinuses …
Lymph from the afferent lymphatic vessel spreads over the lobule’s apical surface in the subcapsular sinus, moves down its sides through lateral transverse sinuses (see Figure 2) and then flows through medullary sinuses surrounding the medullary cords and exits via the efferent lymphatic vessel in the hilus.
Lymph node 9 | Digital Histology
The medulla contains medullary cords and medullary sinuses located between the cords. The medullary cords are composed primarily of B lymphocytes and plasma cells along with macrophages, lymphocytes and reticular cells.
SBPMD Histology Laboratory Manual - Columbia University
Lymphocytes are seen in the medullary sinuses, which are discontinuously lined by endothelial cells. The medullary cords are more cellular and consist of reticular cells, lymphocytes and a number of plasmablasts and plasma cells. Plasma cells are smaller than plasmablasts.
