Q

the right lymphatic duct drains:

A

the upper right quadrant (head, neck, chest, and arm)

2
Q

where does the right lymphatic duct join the venous system

A

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

3
Q

the duct that drains 3 quadrants of the body

A

left lymphatic duct (thoracic duct)

4
Q

where does the left lymphatic duct join the venous system

A

left subclavian and internal jugular veins

5
Q

defense cells (lymphocytes) proliferate in the nodes and enter lymph system

A

hemopoiesis

6
Q

what do the submental lymph nodes drain

A

chin, lower lip, floor of mouth, apex of tongue, and mandibular incisors and associated periodontium

7
Q

the submental nodes drain into the

A

submandibular or directly into deep cervical nodes

8
Q

the submandibular node drains:

A

the cheek, upper lip, body of tongue, anterior hard palate, and teeth associated tissue (except mandibular incisors and max 3rd molars)

9
Q

the submandibular nodes are secondary nodes for:

A

facial nodes, submental nodes, and lymph nodes of sublingual and submandibular salivary glands

10
Q

what does the submandibular node drain into

A

superior deep cervical lymph nodes located deep in neck

11
Q

the nodes are located along the external jugular vein superficial to the sternocleidomastoid (SCM) muscle

A

external jugular lymph nodes

12
Q

this chain of nodes lie along the carotid sheath deep to the SCM muscle

A

deep cervical lymph nodes

13
Q

these nodes are superficial to the SCM muscle at the region of the clavicle

A

anterior jugular lymph nodes

14
Q

these nodes can be palpated by the having the patient turn their head exposing the SCM muscle

A

Deep cervical lymph nodes

15
Q

superior deep cervical nodes are primary nodes for:

A

posterior nasal cavity and hard palate, soft palate, MAXILLARY 3RD MOLARS, and base of tongue

16
Q

these nodes are commonly secondary nodes for most areas of head and neck

A

superior deep cervical nodes

17
Q

these nodes are commonly enlarged with tonsillitis and sore throat

A

jugulodigastric lymph nodes

18
Q

where are the jugulodigastric nodes located

A

below the angle of the mandible

19
Q

which nodes supply the tonsils

A

juglulodigastric

20
Q

masses of lymph tissue that aren’t enapsulated and don’t lie along lymphatic vessels

A

tonsils

21
Q

which tonsil isn’t paired and is also called adenoids

A

pharyngeal tonsil

22
Q

what drains the tonsils

A

superior deep cervical nodes especially jugulodigastric lymph nodes

23
Q

3 ways dental infections can spread

A

blood stream, lymphatics, or tissue spaces

24
Q

where do dental infections drain into

A

the pterygoid plexus

25
Q

increased size and change in consistency of lymph node, due to inc number and size of lymphocytes within the node as a result of infection

A

lymphadenopathy

26
Q

spread of cancer cells from original site to another; nodes are hard and fixed but not tender

A

metastasis

27
Q

diffuse swelling of soft tissue spaces; present as painful firm swelling

A

cellulitis

28
Q

Cellulitis of submandibular space due to untreated infection of mandibular teeth

A

Ludwig’s angina
