Where Are Lymph Nodes Located in the Body?
Lymph nodes play an essential function in our body immune system, serving as filters for hazardous compounds as well as assisting combat infections. Recognizing where lymph nodes are located in the body can supply useful insight into how they operate and just how diseases can affect them. In this post, we will certainly explore the main places of lymph nodes in the human body and their significance.
Lymph nodes are little, bean-shaped structures located throughout the body. They belong to the lymphatic system, which is a network of vessels as well as body organs that bring and filter lymph, a liquid that contains leukocyte, healthy proteins, and waste items. Lymph nodes are attached by lymphatic vessels as well as are purposefully positioned to obtain as well as process lymph.
Head and also Neck
In the head and neck region, lymph nodes lie in numerous locations. The cervical lymph nodes are positioned in the neck as well as are separated right into anterior as well as posterior chains. The submandibular lymph nodes are located beneath the reduced jaw, while the submental lymph nodes are found beneath the chin. Additionally, lymph nodes can be located along the sides as well as back of the neck.
Furthermore, lymph nodes exist in the facial area. The preauricular lymph nodes lie in front of the ear, while the parotid lymph nodes are positioned near the parotid gland. Various other face lymph nodes consist of the buccal, submandibular, as well as submental lymph nodes.
In the scalp, occipital lymph nodes can be discovered at the base of the head, while shallow parotid lymph nodes are placed near the ear. The deep parotid lymph nodes lie within the parotid gland itself.
In addition, lymph nodes can be discovered in the mouth. The tonsillar lymph nodes are located near the tonsils, as well as the sublingual lymph nodes can be located underneath the tongue.

- Submandibular lymph nodes
- Submental lymph nodes
- Face lymph nodes
- Preauricular lymph nodes
- Parotid lymph nodes
- Buccal lymph nodes
- Occipital lymph nodes
- Superficial parotid lymph nodes
- Deep parotid lymph nodes
- Tonsillar lymph nodes
- Sublingual lymph nodes
Upper Body
In the top body, lymph nodes are discovered in the axillary region, typically called the underarm. These axillary lymph nodes are responsible for obtaining lymph from the upper arm or legs, breast wall surface, and bust cells.
Additionally, lymph nodes lie in the thoracic region. The mediastinal lymph nodes are positioned within the mediastinum, which is the main area of the breast. They get lymph from the lungs, esophagus, as well as other structures within the thoracic tooth cavity.
In the stomach, mesenteric lymph nodes are found along the mesentery, a layer of tissue that attaches the intestinal tracts to the back of the abdominal wall surface. These nodes get lymph from the gastrointestinal system.
Moreover, lymph nodes exist in the mammary region, near the busts. The pectoral lymph nodes are located within the pectoral muscles, while the subareolar lymph nodes are located under the areola of the nipple area.

- Mediastinal lymph nodes
- Mesenteric lymph nodes
- Pectoral lymph nodes
- Subareolar lymph nodes
Reduced Body
In the lower body, lymph nodes lie in numerous regions. In the inguinal location, which is the groin area, inguinal lymph nodes can be found. These nodes get lymph from the lower arm or legs, exterior genitalia, and also reduced abdominal wall surface.
In addition, lymph nodes are situated in the pelvic region. The common iliac lymph nodes are placed near the usual iliac arteries, while the internal as well as external iliac lymph nodes lie along the matching capillary. These nodes receive lymph from the pelvic organs, such as the bladder, uterus, and rectum.
- Inguinal lymph nodes
- Common iliac lymph nodes
- Inner iliac lymph nodes
- Exterior iliac lymph nodes
Other Areas
In addition to the key areas mentioned over, lymph nodes can likewise be located in various other locations of the body. As an example, lymph nodes exist in the axilla, or armpit, region. These axillary lymph nodes obtain lymph from the upper arm or legs, chest wall surface, and also bust tissue.
Moreover, lymph nodes can be located in the popliteal region, which is the back of the knee. The popliteal lymph nodes receive lymph from the reduced arm or legs as well as feet.
- Axillary lymph nodes
- Popliteal lymph nodes
Final thought
Lymph nodes are dispersed throughout the body as well as play an important role in maintaining a healthy immune system. Comprehending vision their locations permits medical care specialists to analyze as well as identify diseases or infections that might impact these nodes. From the head as well as neck to the top and lower body, lymph nodes act as crucial components of our immune defense, filtering system lymph as well as aiding in the battle versus infection.
If you notice any swelling, tenderness, or other modifications in lymph nodes, it is important to speak with a medical care professional for appropriate examination as well as diagnosis.
