L5: Cervical lymph nodes and neck lumps Flashcards
Where does lymph drain into?
Venous circulation
What lymphnodes drain the tissues related to the eye?
Pre-auricular (in conjuctivitus, patients may present with a slight lump in front of their ear)
What does the submental nodes drain?
- lips
- chin
- tip of tongue
Where do the submental nodes drain into?
The submental lymph nodes drain into the submandibular lymph nodes
When could you palpate submental/submandibular lymph nodes?
Ulcers in mouth/gum/lip, as the nodes enlarge secondary to inflammation of those tissues
Behind what muscle do the deep nodes lie?
SCM, along the length of the carotid sheath
What are the names of the deep lymph nodes?
- Jugulo-digastric (as found near posterior belly of digastric muscle, and near IJV, behind the mandible: drains palatine tonsil, oral cavity, tongue)
- Jugulo-omohyoid (drains oral cavity, posterior tongue, aerodigestive tract, thyroid gland)
- Supraclavicular (near base of posterior triangle, drain parts of the thorax and abdomen)
What node often swells up during tonsilitis?
Jugulo-digastric
Why would deep lymph nodes be enlarged?
-from fluid from the superficial nodes
OR
-directly from structures within the neck e.g. thyroid/posterior tongue, as these drain directly into the deep nodes
What node swells up if there is pathology within the abdomen or the thorax?
Supraclavicular
What node swells when you have a mouth ulcer on the inner lip/tip of tongue?
Submental lymph node (may drain onto submandibular nodes)
What is Waldeyer’s Ring?
An annular (ring shaped) collection of lymphoid tissue which surrounds the upper digestive tract -first line of defence against certain pathogens entering the body
What tonsils are affected by tonsilitis?
Palatine tonsils (visible)
What tonsils make up Waldeyer’s Ring?
- pharyngeal tonsil (back of nose)
- tubal tonsils (small, near to pharyngeal tonsils)
- palatine tonsils
- lingual tonsils (base of posterior tongue)
What type of tissue are tonsils?
Lymphoid tissue
