`1 Superficial group.

`2 - Deep group.

`Each group contains transverse &vertical (mid line.& 2 laterales)

`All the superficial system drains intothe deep system.


3/19

`Efferents of deep cervical lymph nodes

drianed into the which drain into:`A- on the right side right lymphatic

duct.

`B- on the left side into the thoracic

duct

`Both the right lymphatic duct and thoracic

duct drain into junction of subclavian andinternal jugular veins on their own side.

`.


4/19

`- Vertical group lies along the internal jugular vein.

`- Transverse group.

`The vertical group is formed of:

`1-Superior deep cervical lymph nodes::

`2 Inferior deep cervical lymph nodes


5/19

`The vertical group is formed of:

`1 Superior deep cervical lymph nodes:

Ìn the upper part of internal jugular most of them

deep to sternomastoid and few extended beyond

it.

`

Ex: jugulo digastric lymph nodes.`2 Inferior deep cervical lymph nodes:

Àre partly deep to the lower part of sternomastoid.

`Related to brachial plexus and subclavian vessels.

Èx: jugulo omohyoid lymph nodes.


6/19

`It forms a ring called Waldeyer's ring. This

ring is formed of:

1-Pharyngeal tonsil (adenoid).

2-Tubal tonsil (around the pharyngeal

opening of the auditory tube in the

nasopharynx).

3-Palatine tonsil.4-Lingual tonsil in the posterior third of

the tongue.


7/19

`The transverse group

`1.Occipital lymph nodes :

`2. postauricular lymph nodes ( mastoid nodes

) .

`3- Parotid lymph nodes (periauricular)

`4- The submandibular lymph nodes

`5- Submental lymph nodes:


8/19

`The vertical group of superficial lymph nodes

`is in the form of two vertical columns:

`1. A mid line vertical column lies along the

`anterior jugular vein.`2. A vertical lateral column along the external

jugular vein in the posterior triangle & superficial

to the sternomastoid muscle.


9/19

1. Submental.

2. Submandibular

(Submaxillary)

Anterior Cervical

Lymph Nodes (Deep)

3. Prelaryngeal.

4. Thyroid.

5. Pretracheal.

6. Paratracheal.

`Lymphatic drainage of the deepertissue of head and neck:

`

`The deeper tissue of the head and neckdrain to the deep cervical lymph nodeseither directly or indirectly by:

`1- The para tracheal lymph nodes:

`2-- The retero pharyngeal lymph nodes:


13/19

`1 Above the vocal cord drained into the

upper deep deep cervical lymph nodes.

`2- Below the vocal cord drained into the

lower deep cervical lymph nodes.

`3 -few lymphatic pass to pretracheal and

prelaryngeal then to deep cervical lymph

nodes

`Vessels ofthe gums end in the sub mandibuler lymph

nodes.

`*Hard palate end in the upper deep cervical

nodes and retro pharyngeal lymph node.`* The soft palate partly in upper cervical lymph

node and retro pharyngeal lymph node.

`* The anterior part of the floor of mouth go to inferior

nodes of upper deep cervical group`* The rest of floor to sub manbidular and upper deep

cervical nodes.

`


16/19

`The teeth: to sub mandible and deep cervical

`lymph need.

`The tonsile: most of them end in the jugulo

digastric nodes


17/19

`1-Anterior 2/3 of tongue

`Tip sub mental nodes.

`Sides sub mandible nodes.

`Central part deep cervical lymph

node.

`2- posterior 1 /3 of tongue

`It drains into: Deep cervical lymph nodes


18/19

`The anterior part of nasal cavity drain to

submandibluer nodes.

`*The remainder of nasal cavity para nasalsinuses, nasopharynx and pharyngeal end of on

auditory tube drain to upper deep cervical nodes

directly or through reteropharyngeal.

`*The posterior part of floor of nasal cavity is

drain to parotid group ofnodes
