Exam 2: Lymphatics Of Head And Neck Flashcards
3 main functions of lymphatic system
- Picks up protein molecules
- Returns excess tissue fluid
- Products lymphocytes
Lymph nodes
Swellings found along lymphatic system
Lymph node function
Produce lymphocytes
Act as filters for lymph
Afferent lymph vessels
Drain lymph TO a node
Efferent lymph vessels
Drain lymph FROM a node
Lymph nodes contain _____ tissue
Reticular
Lymph is moved by
Skeletal muscle contraction
Superficial nodes of the head
- Occipital
- Mastoid
- Parotid
Occipital node location
Apex of posterior triangle
Mastoid node location
Behind ear
Parotid node location
Surface of parotid gland
Superficial nodes of neck
- Submandibular
- Submental
- Anterior cervical
- Superficial cervical
Superficial cervical is a chain that runs on _____ and with ______.
Runs on SCM
With external jugular vein
Deep cervical nodes
- Jugulodigastric
2. Jugulo-omohyoid
Both deep cervical nodes drain the
Tongue
Jugulodigastric node location
Near posterior belly of digastric
Jugulodigastric node also drains the
Palatine tonsil
Jugulo-omohyoid node location
Intermediate tendon of omohyoid
Deep cervical nodes follow course of
Internal jugular vein
All lymphatics of the head and neck drain into
Deep cervical nodes
Efferents of deep cervical nodes form
Right and left jugular trunks
Right jugular trunk drains into
Junction between internal jugular and subclavian veins
Left jugular trunk drains into
Thoracic duct
Lymphatic system very important for tracking
Spread of cancer cells
