Q

primary nodes than drain into

A

secondary node (central node)

17
Q

In the outer tissue of the body, smaller lymphatic vessels containing lymph converge into

A

larger lymphatic ducts

18
Q

larger lymphatic ducts empty into

A

venous system of the blood in the thorax (chest area)

19
Q

The lymphatic system of the right side of the head and neck converges by way of the right jugular trunk joining

A

the lymphatic system from the right arm and thorax (chest) to form the right lymphatic duct

20
Q

right lymphatic duct drains into

A

venous component at the junction of the right subclavian and right internal jugular veins

21
Q

The lymphatic vessels of the left side of the head and neck converge into the left jugular trunk, actually a short vessel, and then into

A

the thoracic duct

22
Q

the thoracic duct joins

A

the venous component at the junction of the left subclavian and left internal jugular veins

23
Q

The lymphatic system from the left arm and thorax also joins

A

the thoracic duct

24
Q

The thoracic duct is much larger than

A

the right lymphatic duct because it drains the lymph from the entire lower half of the body(both the right and left sides)

25
The resultant increase in size and change in consistency of the lymphoid tissue is considered
lymphadenopathy
26
In some cases of infection, the lymph node can undergo inflammation or
lymphadenitis
27
lymphadenitis occurs with microbial infections such as
Staphylococcus aureus and Streptococcus pyogenes infections locally with tonsillar or oral abscesses as well as systemically with mononucleosis or HIV infections
28
Infectious mononucleosis is caused by
Epstein-Barr virus (EBV)
29
infectious mononucleosis in teenagers and young adults frequently there is
pharyngitis and inflamed palatine tonsils with exudate
30
The lymph nodes associated with the head and neck can also be involved in the spread of infection such as
dental or odontogenic infection from the teeth
31
This spread of infection occurs along the
connecting lymphatic vessels of the involved nodes.
32
cancer can also start within the nose as with
lymphoma, which includes both Hodgkin and non-Hodgkin disease. Lymph nodes can be also involved in the spread of certain cancers (carcinomas) from epithelial tissue in the region they filter
33
The spread of a cancer from the original or primary site of the neoplasm to another or secondary site is considered
metastasis
34
Primary nodes of the primary site then drain to the secondary site to which the cancer will later
metastasize
35
when lymph nodes are involved with cancer they become
bony hard, and possible fixed to surrounding tissue, structure, organs making them non mobile
36
are cancerous nodes tender
not usually but could be with late findings when cancer has spread to surround nerves
37
Lymphomas are
malignant neoplasms of component cells of lymphoid tissues
38
Broad division of the group into Hodgkin and non-Hodgkin lymphomas
is widely accepted
