Lymph Node Structure | Best Explanation Ever | Lymphomas made Easy 1
Lymph nodes are kidney or oval shaped and range in size from 0.1 to 2.5 cm long. Each lymph node is surrounded by a fibrous capsule, which extends inside a lymph node to form trabeculae.The substance of a lymph node is divided into the outer cortex and the inner medulla. These are rich with cells.The hilum is an indent on the concave surface of the lymph node where lymphatic vessels leave and blood vessels enter and leave.
Lymph enters the convex side of a lymph node through multiple afferent lymphatic vessels and from here flows into a series of sinuses.[3] After entering the lymph node from afferent lymphatic vessels, lymph flows into a space underneath the capsule called the subcapsular sinus, then into cortical sinuses. After passing through the cortex, lymph then collects in medullar...

Pelvic lymph nodes
Lymphatic drainage of tissues of the body is more important than we realise and we take it for granted most of the time. The lymphatic fluid from the lower limbs and the pelvic region flows through a number of lymph nodes in the pelvis to find its way to the abdomen. Let's have a look at these groups of lymph nodes and try to better understand their anatomy.

Anatomy of a lymph node
We talk about the lymphatic system a lot, but what exactly is the structure of a lymph node? What does it look like inside? What are the cells of a lymph node? What does it do? How does it work?
Well, I'd take any immunology I talk about with a pinch of salt, but I can describe the anatomy of a lymph node. It might help you understand how the immune system works.

Lymph nodes are kidney or oval shaped and range in size from 0.1 to 2.5 cm long. Each lymph node is surrounded by a fibrous capsule, which extends inside a lymph node to form trabeculae.The substance of a lymph node is divided into the outer cortex and the inner medulla. These are rich with cells.The hilum is an indent on the concave surface of the lymph node where lymphatic vessels leave and blood vessels enter and leave.
Lymph enters the convex side of a lymph node through multiple afferent lymphatic vessels and from here flows into a series of sinuses.[3] After entering the lymph node from afferent lymphatic vessels, lymph flows into a space underneath the capsule called the subcapsular sinus, then into cortical sinuses. After passing through the cortex, lymph then collects in medullary sinuses. All of these sinuses drain into the efferent lymph vessels to exit the node at the hilum on the concave side.
A lymph node is divided into compartments called nodules (or lobules), each consisting of a region of cortex with combined follicle B cells, a paracortex of T cells, and a part of the nodule in the medulla. The substance of a lymph node is divided into the outer cortex and the inner medulla.The cortex of a lymph node is the outer portion of the node, underneath the capsule and the subcapsular sinus. It has an outer part and a deeper part known as the paracortex. The outer cortex consists of groups of mainly inactivated B cells called follicles. When activated, these may develop into what is called a germinal centre.The deeper paracortex mainly consists of the T cells. Here the T-cells mainly interact with dendritic cells, and the reticular network is dense.
The medulla contains large blood vessels, sinuses and medullary cords that contain antibody-secreting plasma cells. There are less cells in the medulla.
The medullary cords are cords of lymphatic tissue, and include plasma cells, macrophages, and B cells.
Cells
In the lymphatic system a lymph node is a secondary lymphoid organ.Lymph nodes contain lymphocytes, a type of white blood cell, and are primarily made up of B cells and T cells. B cells are mainly found in the outer cortex where they are clustered together as follicular B cells in lymphoid follicles, and T cells and dendritic cells are mainly found in the paracortex.
There are fewer cells in the medulla than the cortex.[2] The medulla contains plasma cells, as well as macrophages which are present within the medullary sinuses.
As part of the reticular network, there are follicular dendritic cells in the B cell follicle and fibroblastic reticular cells in the T cell cortex. The reticular network provides structural support and a surface for adhesion of the dendritic cells, macrophages and lymphocytes. It also allows exchange of material with blood through the high endothelial venules and provides the growth and regulatory factors necessary for activation and maturation of immune cells.

Isolation of Murine Lymph Node Stromal Cells - a 2 minute Preview of the Experimental Protocol

University of Basel and University Hospital Basel, Department of Biomedicine, Immunoregulation;
Isolation of lymph node stromal cells is a multistep procedure including enzymatic digestion and mechanical disaggregation to obtain fibroblastic reticular cells, lymphatic and blood endothelial cells. In the described procedure, a short digestion is combined with automated mechanical disaggregation to minimize surface marker degradation of viable lymph node stromal cells.

Lymphatic drainage of tissues of the body is more important than we realise and we take it for granted most of the time. The lymphatic fluid from the lower limbs and the pelvic region flows through a number of lymph nodes in the pelvis to find its way to the abdomen. Let's have a look at these groups of lymph nodes and try to better understand their anatomy.

We talk about the lymphatic system a lot, but what exactly is the structure of a lymph node? What does it look like inside? What are the cells of a lymph node? What does it do? How does it work?
Well, I'd take any immunology I talk about with a pinch of salt, but I can describe the anatomy of a lymph node. It might help you understand how the immune system works.
