which of the following statements explains why facial and dental infections can lead to serious complications?

valves in the veins are mostly absent in the head & neck area

which of the following tissues is not supplied by the lingual artery?

mylohyoid muscle

the dental professional must be able to locate the larger blood vessels of the head & neck because these vessels may become compromised due to a disease process or during a dental procedure such as a local anesthetic injection.

both statement & reason are correct and related

upper extemity or arm

which of the following arteries is a direct branch of the aorta?

brachiocephalic artery

which term is used to describe a blood vessel that travels to the heart carrying blood?

vein

which are the major arteries that supply the head & neck?

common carotid, subclavian

blood vessels are more numerous than lymphatic vessels. however, the venous portion mainly parallels the lymphatic vessels in location.

first is false, second is true

what does the term anastomosis mean?

communication of blood vessels with another connecting channel

the common carotid artery is branchless and travels up the neck, lateral to the trachea and larynx to the upper border of the thyroid cartilage. the common carotid artery travels in a sheath deep to the superior, middle, and inferior pharyngeal muscle.

first is true, second is false

which of the following terms describes the infectious process created by normal flora becase the bodys defenses are compromised?

opportunistic infections

which of the following disease states can cause a periapical abscess?

progressive caries

a dental professional should understand the infectious process that allows microorganisms to create disease. certain nonresident microorganisms can invade and initiate an infection

both are true

which of the following infections directly involves teeth and associated tissues and thus is a dental infection?

odontogenic infection

which of the following is considered the main role of the lymph nodes in relationship to the lymph within the lymphatic vessels?

filtration

which of the following lymph nodes are not considered to be superficial lymph nodes located in the head?

retropharyngeal lymph nodes

a dental profession needs to check carefully for an palable nodes of the head and neck during an extraoral examination because the palable lymph nodes may help determine where a disease process is active

both the statement and reason are correct and related

the submandibular lymph nodes are located at the inferior border of the ramus of the mandible, just superficial to the submandibular salivary gland and within the submandibular fascial space. these nodes drain the cheeks, upper lip, body of the tongue, anterior portion of the hard palate, as well as the mandibular incisors and maxillary third molars

first is true, second is false

which of the following structures allow lymph to flow directly into the surrounding lymph nodes?

afferent vessel

the retroauricular lymph nodes are also known by which of the following?

mastoid lymph nodes

the occipital nodes can be palpated during the extraoral exam by asking the patient to tilt his or her head to the left and then to the right with the chin upward because the occipital lymph nodes empty into the inferior deep cervical nodes of the neck

the statement is not correct, but the reason is correct

the lymphatics are a portion of the immune system, and they help fight disease processes. another component of the lymphatic system is the thymus gland because it works within immune system.

first is true, second is false

the lymphatics of the right side of the head and the neck converge by way of the right jugular trunk. then there lymphatics join the lymphatics from the right arm and thorax to form the thoracic duct.

first is true, second is false

which of the teeth listed below, when infected, do not initially drain into the submandibular lymph nodes but into another group of lymph nodes?

max third molars
