Occipital lymph nodes: 1 to 5, located on the superficial surface of the occipital bone of the trapezius muscle, subcutaneous part of the occipital part, and deep surface of the splenium capitis muscle. They are divided into superficial and deep occipital lymph node groups. There are about 1 to 3 superficial occipital lymph nodes and 1 to 2 deep occipital lymph nodes. Collect lymph from the occipital area, the skin above the neck, and lymph from the deep muscles of the neck. The efferent ducts of the occipital lymph nodes drain into the superficial cervical lymph nodes and accessory neural lymph nodes. When occipital lymph nodes swell, they can compress the occipital nerve, causing pain in the area where the nerve is distributed.

Also known as mastoid lymph nodes, there are 2 to 3 lymph nodes. They are located on the deep surface of the deep fascia between the mastoid part and the back of the auricle and the front edge of the insertion point of the mastoid muscle. They are located on the deep side of the postauricular muscle and are arranged along the postauricular artery. Collect lymph from the parietal area, temporal area, mastoid area, tympanic membrane, the back of the auricle and the posterior wall of the external auditory canal. Its output tube enters the subauricular lymph node forward and then injects into the superficial cervical lymph node, or enters through the anterior and posterior edges of the sternocleidomastoid muscle. Its deep superior cervical lymph nodes and accessory neural lymph nodes. In children, the occurrence rate of lymph nodes behind the ear is higher, but in the elderly, lymph nodes behind the ear are often absent. The lymph nodes in this range can go directly to the subauricular lymph nodes and the deep upper cervical lymph nodes.

Parotid lymph nodes: They are a large group of lymph nodes on the face, usually about 20. According to the positional relationship between lymph nodes and parotid gland, they can be divided into: superficial parotid gland lymph nodes and deep parotid gland lymph nodes.

1. Superficial lymph nodes of parotid gland: 3~5

2. Deep parotid lymph nodes: 5 to 10 located in the parotid gland and gathered around the retromandibular vein and facial nerve. The deep parotid lymph node efferent duct terminates along the external carotid artery in the cervical digastric lymph node of the deep superior cervical lymph node.

Facial lymph nodes: small and unstable, generally located in the subcutaneous cellular tissue of the face, superficial to the facial muscles, and arranged along the facial artery and facial vein. When there is inflammation or tumor on the face, facial lymph nodes can cause reactive enlargement or be discovered to be involved and swollen. divided into four groups

Sentinel lymph node: This lymph node is clinically important. It receives lymph from the back of the tongue, nasopharynx, palatine tonsils and the root of the nose. When inflammation exists in its collection area or cancer metastasis occurs, this lymph node is often involved first.

Virchow's lymph node: clinically a single enlarged supraclavicular lymph node. Usually refers to the swollen lymph node on the left supraclavicular bone.
