Finding the Nodes
There are a lot of lymph nodes that are distributed in many different parts around the body. Lymph nodes are distributed in the body, where there are some located in the human head and neck, some in the arms and some, in the lower limbs. In a human’s body, an estimated 500-600 lymph nodes are scattered in the different areas mentioned.
There are many lymph nodes located in the human head and neck. There are five areas in the human head and neck where lymph nodes are located. First, there is what is called cervical lymph nodes. A cervical lymph node can be an anterior cervical and a posterior cervical. Anterior cervical lymph node refers to a cervical lymph node that can either be deep or shallow. It is in the sternocleidomastoid where an anterior cervical lymph node can either lie beneath or above. A posterior cervical lymph node is the type that is usually enlarged because of the infections occurring in the upper respiratory area.
Another lymph node in the human head and neck is the tonsillar lymph node which is found just below the mandible’s angle. What a tonsillar does is to drain the regions of posterior pharyngeal and tonsillar. Sub-mandibular is another lymph node that runs on either side of the jaw, specifically on the underside. The floor of the human mouth is drained by this lymph node. Sub-mental is another lymph node in the head and beck that is located below the chin, which functions to drain the intra-oral cavity and the teeth. Supraclavicular is located above the clavicle, with a function of partially draining the abdomen and the thoracic cavity.
Lymph nodes of the arms include medial, central, posterior, anterior and lateral glands. These lymph nodes are the arm’s deep lymph glands. There are also superficial lymph glands. Examples of which are deltoideopectoral and supratrochlear glands.
A lymph node in the human’s lower limbs is called inguinal lymph node.
