Lymphatic of the head and neck Flashcards
What is the lymphatic system of the head and neck like?
Extensive network of small lymphatic capillaries that drain tissue fluid.
This fluid passes through regional lymph nodes and also through a terminal group of lymph nodes, the deep cervical lymph nodes, before being returned to the 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.
The chain of lymph nodes extend from the base of the skull to the root of the neck at the thoracic inlet.
What is at the ifnerior end of the deep cervical chain of lymph nodes?
The efferent lymphatic vessels join together to form the jugular lymph trunk on each side.
Where do the efferent lymphatics from these jugular lymph trunks drain into:
On the right?
On the left?
Right- Right lymphatic duct
Left- Thoracic duct then into left subclavian
What are the parotid glands location and their drainage?
Location- On or in parotid gland
Drain lymph from- Scalp around parotid gland, lateral parts of the eyelids, and middle ear.
What are the buccal glands location and their drainage?
Location- Over buccinator muscle
Drain from cheek region
What are the submental glands location and their drainage?
Location- Anteriorly just under mandible
Lymph- Anterior tongue tip, central part of the floor of the mouth and chin
What are the submandibular glands location and their drainage?
Location- Below lower border of body of mandible
Drainage- Front of scalp, nose, lips, air sinuses – ethmoidal, frontal, maxillary; teeth, gums, anterior tongue, floor of the mouth; and efferent lymphatics from submental nodes
What are the mastoid glands location and their drainage?
Location- Over mastoid process
Drainage- Middle region of scalp and external auditory meatus
What are the occipital glands location and their drainage?
Location- Overlie occipital process
Drainage- Back of scalp
Efferent lymphatic vessels from what?
All of these groups of lymph nodes carry lymph to the deep cervical nodes.
What is the location and drainage of the anterior cerival nodes?
Lie along anterior jugular veins
Superficial structures of anterior neck
What is the location and drainage of the superficial cervical?
Location- Lie along external jugular vein
Drainage- From parotid nodes, and the angle of the mandible, structures that lie at the junction between the neck, the face and the scalp
What is the location and drainage of the retropharyngeal nodes?
Location- lie between the pharynx and the vertebral bodies
Drainage-Nasopharynx, auditory tube, and the upper cervical vertebral column
What is the location and drainage of the laryngeal nodes?
Location- Lie around the cricothyroid ligament
Draiange- Larynx and adjacent structures
