arteries, veins, salivary glands, lymph nodes

the carotid artery divides into two branches. what are they?

interal carotid artery and external carotid artery

this artery branches off near the hyoid bone and enters the tongue to supply the floor of the mouth, adjacent gingiva, and sublingual gland

lingual artery

this artery supplies blood to structures adjacent to the pharynx

facial artery

this artery consists of three branches that supplies blood to the mandibular teeth, muscles of mastication, maxillary teeth, and palate

maxillary artery

numerous deep veins drain blood from the upper part of the face, the tissue of lips, muscles around the mouth, posterior part of the nasal cavity, maxillary alveolar process, and maxillary teeth into the

pterygoid plexus

veins of the pterygoid plexus empty into the short

maxillary vein

the blood then passes to the next vein to drain those areas that received blood through the maxillary and superficial temporal arteries

retromandibular

an important superficial vein that also drains blood from the face. receives blood from the area around the eyes, nose, lips, and muscles of mastication

facial vein

the maxillary vein, retromandibular vein, lingual veins, and deep facial vein drains into the common facial vein and then into the

internal jugular vein

venous pathway

pterygoid plexus, maxillary vein, facial/retromandibular, lingual, common facial vein, internal jugular vein, superior vena cava, heart

infection in the area of the chin, tip of tongue, anterior floor of mouth, lower lip, and adjacent gingiva all drain into the

submental lymph node

infection will then drain into the ______ which also collects fluid from maxillary and mandibular teeth

submandibular

infection will then drain into the ____ which also receives lymph from areas around the parotid gland

superficial parotid

infection will then drain into the ______ chain of lymph nodes

deep cervical

lymph pathway

submental, submandibular, superficial parotid, then deep cervical
