Cortex of Lymph Node | Complete Anatomy - Elsevier
The cortex is the outer portion of the node, consisting mainly of dense lymphoid tissue and follicles (Dorland, 2011). The cortex is distinguishable by the presence of spherical lymphoid follicles, which are surrounded and separated by interfollicular (or diffuse) cortex.
Lymph node - Wikipedia
In the lymphatic system, a lymph node is a secondary lymphoid organ. A lymph node is enclosed in a fibrous capsule and is made up of an outer cortex and an inner medulla. Lymph nodes become inflamed or enlarged in various diseases, which may range from trivial throat infections to life-threatening cancers.

2024年12月4日 · Each lymph node is divided into two general regions, the capsule and the cortex. The capsule is an outer layer of connective tissue. Underlying the capsule is the cortex, a region containing mostly inactivated B and T lymphocytes plus numerous accessory cells such as dendritic cells and macrophages.

2023年8月3日 · The lymph node is divided into an outer cortex and an inner medulla. Histological staining of the node reveals that the cortex stains darker than the medulla with hematoxylin and eosin (H&E) due to its higher cell content.

2023年7月25日 · The cortex of the lymph node is the layer beneath the subcapsular sinus. The cortex is formed of the outer cortex and the inner part known as the paracortex. The outer cortex layer is also named the B-cell layer, is rich in CXCR5 chemokines, and consists mainly of B-cells arranged into follicles.

2023年8月3日 · Cross sectional analysis of a lymph node reveals that it is subdivided into three regions: Outer cortex. The outermost layer is the cortex. It is made up of a subcapsular sinus, cortical sinus and lymphoid nodules. The subcapsular sinus is the first space that lymph fluid from the afferent channels enters within the node.
Lymph Node - an overview | ScienceDirect Topics
The lymph node parenchyma is composed of a cortex, which is the outer layer of lymphoid tissue, and the medulla, which is the inner layer of cords and sinuses. The cortex consists of follicles and the interfollicular space.

Lymph node structure: This diagram of a lymph node shows the outer capsule, cortex, medulla, hilum, sinus, valve to prevent backflow, nodule, and afferent and efferent vessels. Lymph nodes are found throughout the body, and are typically 1 to 2 centimeters long.
Lymph Node - an overview | ScienceDirect Topics
The lymph node is a complex, kidney-shaped structure usually located at the junction of several lymph vessels. From an anatomic perspective, nodes consist of a cortex (outer portion), a paracortex, and a medulla (inner portion). The sections of lymph nodes are shown in Figure 1-12 and Figure 1-13.
The Lymph Nodes: Interactive Anatomy Model - Innerbody
2024年12月9日 · Many tiny masses of cells known as lymphatic follicles make up the bulk of the outer cortex. Each lymphatic follicle contains many B lymphocytes (B cells) that produce antibodies in response to infections. During active infections, the follicles develop germinal centers that act as factories to rapidly produce many B cells to fight the infection.
