The former region homes the thyroid gland, throat, esophagus, and also numerous blood vessels. On the other hand, the posterior region has essential structures such as the spinal cord, vertebral column, as well as muscular tissues that promote head movements.
In addition, the neck is further identified right into several regions based upon the place of lymph nodes. These regions, referred to as levels, are typically determined utilizing a standard category called the Neck Level System.
- Degree I: The lymph nodes in this area are located near the submental triangle, which is beneath the chin.
- Level II: These lymph nodes are positioned along the upper component of the interior jugular blood vessel, extending from the base of the skull to the hyoid bone.
- Degree III: Positioned along the middle part of the interior jugular vein, these lymph nodes prolong from the hyoid bone to the lower side of the cricoid cartilage.
- Degree IV: enerflex es bueno o malo These lymph nodes are found below the cricoid cartilage material, reaching the clavicle.
- Level V: Located over the clavicle, these lymph nodes are divided right into two class: Degree Va and also Degree Vb.
Each degree makes up multiple lymph nodes interconnected by lymphatic vessels. By following this category, doctor can evaluate and identify conditions related to particular areas of the neck a lot more accurately.

- Jugulodigastric Lymph Nodes: Found at the angle of the mandible, these nodes drain lymph from the palatine tonsils, base of the tongue, soft taste, as well as posterior pharynx.
- Surface Cervical Lymph Nodes: Situated along the sternocleidomastoid muscular tissue, these nodes receive lymph from the scalp, face, neck, as well as superficial areas of the head.
- Posterior Cervical Lymph Nodes: Positioned in the posterior cervical triangle, these nodes drain lymph from the posterior scalp, neck muscular tissues, and also posterior areas of the head.
- Supraclavicular Lymph Nodes: Positioned over the clavicle bone, these nodes get lymph from numerous areas, including the lungs, esophagus, busts, as well as upper stomach wall.
These lymph nodes work in unison to shield the body from unsafe substances and also infections. When an infection or problem is present in the matching area, the lymph nodes might end up being bigger or tender, indicating an immune action.

Comprehending their specific places as well as the local classification system can dramatically assist healthcare providers in diagnosing as well as treating numerous conditions. Normal self-examination as well as timely medical attention for any concerning modifications in the size or texture of lymph nodes in the neck are critical in preserving total well-being.
