Lymph Drainage Flashcards
What are lymph nodes
Small bean shaped structures lying along course of lymphatic vessels
What are the 2 main functions of lymph nodes
Filtration
Antigen presentation
What are the 3 groups of deep cervical nodes
Superior middle inferior
Where are deep cervical nodes
Extend from base of skull to clavicle
Lie under cover of anterior border of sternomastoid muscle in relation to carotid sheath
What does the superior deep group drain
Soft palate, tonsils, palatoglossal/pharyngeal arches, posterior aspect and base of tongue, pyriform fossa and larynx above vocal folds
Superficial nodes of face and scalp
Upper retropharyngeal nodes
What does the middle deep group drain
Larynx above vocal folds, lower pyriform sinus and posterior cricoid
What does the middle deep group receive secondary drainage from
Deep cervical chain above
Lower retropharyngeal nodes
What does the inferior deep group drain
Thyroid, trachea and cervical oesophagus
Secondarily drain deep cervical chain above and paratracheal nodes
What is the afferents of the submental lymph node
Lower lip, chin, tip of tongue, anterior FOM
What is the efferents of the submental lymph node
Submandibular nodes, jugulo-omohyoid nodes
What is the afferents of the submandibular lymph node
Submental nodes, cheek, nose, upper lip, maxillary teeth, vestibular gingivae, mucosa and gingivae of hard palate, posterior FOM, lateral aspect of anterior 2/3 of tongue
What is the efferents of the submandibular lymph node
