Deep lymph nodes of the head region cannot be palpated during an extraoral exam because of this
These are four groups of superficial cervical lymph nodes
What is submental, submandibular, external jugular, and anterior jugular lymph nodes?
Node level II includes how much of the deep cervical nodes, including the jugulodigastric node
What is the superior 1/3?
What is the lingual tonsil?
What drains into the superior deep cervical lymph nodes, particularly affecting the jugulodigastric lymph node if there is an infection in the region
What are the tonsils?
Deep nodes of the head include these two types
What is deep parotid and retropharyngeal lypmh nodes?
These lymph nodes are located inferior to the chine within the submental fascial space
What is the submental lymph nodes?
Node II is at the greatest risk for involving the spread of this
This tonsil is located in the nasopharynx, posterior to the openings of the auditory tube
What is tubal tonsil?
This is what patients are referring to when they say "tonsils"
What are the palatine tonsils?
Deep parotid lymp nodes consist of this number of nodes
What is up to 10?
These lymph nodes unilaterally drain the cheeks, upper lip, body of the tongue, anterior hard palate, and most of the teeth with associated periodontium and gingiva except for the mandibular incisors and maxillary third molars
What are submandibular lymph nodes?
Node level III is greatest risk for spreading cancers of these specific areas
What is oral cavity, nasopharynx, oropharynx, laryngopharynx, and larynx?
The tubal tonsil is also called this
What is the pharyngotympanic tube?
Palatine tonsils are located between these two pillars
What are the anterior and posterior faucial pillars?
These nodes drain the middle ear, auditory tube, and parotid salivary gland
What are deep parotid lymph nodes?
These nodes empty into the deep cervical nodes and may be secondary nodes for the occipital, posterior auricular, anterior auricular, and superficial parotid nodes
What are the external jugular lymph nodes?
Located at the base of the skull at the posterior border of the attachement of the SCM muscle within the posterior cervical triangle to the level of the clavicle as seen on each axial scan is this
What is node level V?
Unlike lymph nodes, tonsils are located along these
What are lymphatic vessels?
These two vertical folds are formed by what muscles of the soft muscle
What is the palatoglossus muscle that forms the anterior faucial pillar and the palatopharyngeus muscle that forms the posterior faucial pillar?
These nodes are located near the cervical atlas and usually disappear by the age 4-5
What is retropharyngeal lymph nodes?
During an extroral exam of the external and anterior jugular nodes in the middle part of the neck, have the patient turn the head to the contralateral side which makes the important landmark of what muscle more prominant
What is the sternocleidomastoid muscle?
Unlike the deep nodes of the head that cannot be palpated, these nodes can be palpated on each side of the neck
What are deep cervical nodes?
When a patient has a disease process such as infection or cancer active in a region, the regions lymph nodes respond. The resultant dramatic increase in size and change in consistency of the lymphoid tissue are considered this
What is lymphadenopathy?
This tonsil is also called adenoids
What is the pharyngeal tonsil?
