3.3 The Lymphatics of the Head and Neck Flashcards
What is the function of the Lymphatic System?
To drain tissue fluid
What is the pathway for the Lymphatic Drainage of the Head and Neck?
- Regional Lymph Nodes
- Terminal Lymph Nodes
- Deep Cervical Lymph Nodes
- Venous Circulation
What are the Deep Cervical Lymph Nodes?
A group of Lymph Nodes which are found as a linked chain of nodes around the Internal Jugular Vein, and within the Fascia of the Carotid Sheath
Where can the Deep Cervical Lymph Nodes Chain extend from / to?
From the Base of the Skull to the Thoracic Inlet (Root of the Neck)
What do the Efferent Lymphatic Vessels join to form at the inferior end of the Deep Cervical Lymph Nodes Chain?
The Jugular Lymph Trunk (on each side)
Where do the Efferent Lymphatics from the Jugular Trunk drain to on the Right-hand Side of the Body?
The Right Lymphatic Duct
Where do the Efferent Lymphatics from the Jugular Trunk drain to on the Left-hand Side of the Body?
The Thoracic Duct
What are the 6 names of the groups of Lymph Nodes in the Face / Scalp?
- Parotid Nodes
- Buccal Nosed
- Submental Nodes
- Submandibular Nodes
- Mastoid Nodes
- Occipital Nodes
What is the location of the Parotid Nodes?
On / In the Parotid Gland
What is the location of the Buccal Nodes?
Over the Buccinator Muscle
What is the location of the Submental Nodes?
Anteriorly just under the Mandible
What is the location of the Submandibular Nodes?
Below the Lower Border of the Body of the Mandible
What is the location of the Mastoid Nodes?
Overlying the Mastoid Process
What is the location of the Occipital Nodes?
Overlying the Occipital Proturbance
Where do the Parotid Nodes drain Lymph from?
- Scalp surrounding the Parotid Glands
- Lateral Parts of the Eyelids
- The Middle Ear
Where do the Buccal Nodes drain Lymph from?
The Cheek Region
Where do the Submental Nodes drain Lymph from?
- The Anterior Tongue Tip
- The Central Part of the Floor of the Mouth
- The Chin
Where do the Submandibular Nodes drain Lymph from?
- The Front of the Scalp
- The Nose
- The Lips
- The Air Sinuses (Ethmoidal, Frontal, Maxillary)
- The Teeth / Gums
- The Anterior Tongue
- The Floor of the Mouth
- The Efferent Lymphatics from the Submental Lumph Nodes
