lymphatics Flashcards
type of lymphatic vessel in which lymph flows into the lymph node
afferent vessel
type of lymphatic vessel in which lymph flows out of the lymph node in the area of the nodes hilus
efferent vessel
depression on one side of a lymph node where lymph flows out by way of an efferent lymphatic vessel
hilus
method of division of lymph node where lymph flows out by way of an efferent lymphatic vessel
hilus
method of division of lymph nodes in the neck region using roman numerals
levels
tissue fluid that drains from the surrounding region and into the lymphatic vessels
lymph
process in which there is an increase in the size and a change in the consistency of lymphoid tissue
lymphadenopathy
larger lympatic vessels that drain smaller vessels and then empty into the venous system
lymphatic ducts
part of the immune system that consists of vessels, nodes, ducts, and tonsils
lymphatic system
organized, bean shaped lympoid tissue that filters the lymph by way of lymphocytes and is grouped into clusters along the connecting lymphatic vessels
lymph nodes
lymph node that drains lymph from a primary node
secondary node
lymph node that drains lymph from a particular region
primary node
masses of lymphoid tissue located in the oral cavity and pharynx
tonsils
parts of the immune system
vessels
nodes
ducts
tonsils
how do lymphatic vessels run with veins
parallel
lymph nodes contain___ and filter _____
white blood cells(lymphocytes) and toxins
healthy nodes are small, soft, ____
mobile, and cannot normally be palpated
smaller lymphatic vessels converge to form lymphatic
ducts
right lymphatic duct
drains right head, neck, arm, and chest
left thoracic duct
drains left head, neck, arm and chest
drains entire lower body right and left(bigger)
lymphadenopathy is usually in response to an infection or
malignancy
with lymphadenopathy, there is an increase in the number and size of
lymphocytes to fight toxins; allows for palpation of visualization of nodes
primary nodes for max anterior teeth and associated tissue
submandibular
primary nodes for max first and second molars and premolars and associated tissue
submandibular
max third molars and associated tissue
superior deep cervical
mand incisors and associated tissue primary nodes
submental
mand canines, premolars, and molars and associated tissue
submandibular
floor of mouth primary nodes
submental
tongue apex primary nodes
submental
tongue body primary nodes
submandibular
tongue base primary nodes
superior deep cervical
palatine tonsils and lingual tonsil primary nodes
superior deep cervical
parotid salivary gland primary nodes
deep parotid
upper lip primary nodes
submandibular
lower lip primary nodes
submental
chin primary nodes
submental
sublingual salivary gland primary nodes
submandibular
submandibular salivary gland primary nodes
submandibular
superficial nodes
occipital retroauricular anterior auricular superficial parotid facial
can deep lymph nodes be palpated?
cannot be palpated like the superficial nodes
deep nodes
deep parotid
retropharyngeal
superficial cervical nodes
submental
submandibular
external jugular
anterior jugular
deep cervical lymph nodes are located
along the length of the internal jugular vein
deep cervical
superior deep cervical
inferior deep cervical
lingual tonsil is
at base of tongue
palatine tonsil is
anterior and posterior tonsillar pillars
the “tonsils”
pharyngeal tonsils are called
“adenoids”
midline on posterior wall of nasopharynx
what are the three tonsils
lingual
palatine
pharyngeal
where are the axillary nodes located
armpit region(axillary)
they perform the vital function of filtration and conduction of lymph from the upper limbs, pectoral region
and upper back
axillary nodes
