Select the anterior branches of the external carotid artery.

Select the medial branches of the external carotid artery. The artery within this branch cannot be viewed laterally.

The ______ artery is a medial branch from the external carotid artery. It supplies the pharyngeal walls, soft palate, meninges, & pharyngeal tonsils

Select the posterior branches of the external carotid artery.

Select the terminal branches of the external carotid artery.

The maxillary artery of the terminal branch is divided into 3 parts: first, second, and third parts.

The ________ artery of the first part of the maxillary artery of the terminal branch supplies the mand. post. teeth (buccal periodontium & gingiva, floor of mouth & mylohyoid muscle, mental region, and mandibular anterior teeth (facial periodontium & gingiva)

The green arrow is pointing to the _______ artery.

The green arrow is pointing to the _______ artery.

The _______ arteries of the second part of the maxillary artery supply both the anterior and posterior parts of the temporal region & temporalis muscle.

The green arrow is pointing to the _______ arteries.

The green arrow is pointing to the _______ artery.

After the maxillary artery leaves the infratemporal fossa and enters the pterygopalatine fossa, it branches off as the 3rd part to the __________ artery.

The ________ artery supplies the maxillary posterior teeth, buccal periodontium and gingiva, & the maxillary sinus through each tooth’s apical foramen.

The ________ artery branches form the 3rd part of the maxillary artery.

It further divides into the anterior superior alveolar artery & middle superior alveolar artery.

The anterior superior alveolar artery (branching from the infraorbital artery) supplies the:

The middle superior alveolar artery (branching from the infraorbital artery) supplies the:

The green arrow is pointing to the _______ artery.

The green arrow is pointing to the _______ artery.

The green arrow is pointing to the _______ artery.

1. Most veins have valves that prevent backward flow of blood and pooling.

2. Valves increase the potential for and severity of dental infections

1. Veins are smaller in their size and number than arteries.

2. The major veins of the head and neck are the external jugular veins & the internal jugular vein.

The ______ vein drains into the internal jugular vein. This vein begins near the medial canthus of the eye. It drains the nose, lips, eyes, submental & submandibular areas.

Select the tributaries (vein that empties into a larger vein) of the facial vein.

1. An example of venous variability concerns the lingual veins. These include the dorsal lingual veins, deep lingual vein (visible during an IO examination), & the sublingual vein.

2. The lingual veins may join to form a single vessel or may empty into larger vessels separately. They also may drain indirectly into the facial vein or directly into the internal jugular vein.

The ________ veins are important clinically as they are capable of rapid and direct systemic absorption with topical drug placement.

The _________ vein emerges from the parotid gland. It drains the lateral scalp area & pterygoid plexus of veins

Inferior to the parotid gland, the retromandibular vein usually divides into 2 parts. The anterior division joins the facial vein & the posterior division continues its inferior course on the surface of the SCM.

After being joined by the posterior auricular vein, the posterior division of the retromandibular veins becomes the ___________ vein.

The ________ vein drains the lateral scalp & is superficially located in skin covering the temporal region and can sometimes be noted on a patient during an EO examination.

There are 2 divisions: anterior (which joins the facial vein) & posterior (which joins posterior auricular and becomes external jugular vein)

›

The ______ vein begins within the infratemporal fossa by collecting blood from the pterygoid plexus of veins. (deep facial areas)

Through the pterygoid plexus of veins, the _______ vein receives the posterior superior alveolar & inferior alveolar veins.

1. The posterior superior alveolar veins are formed by alveolar and dental branches of the maxilla.

2. The inferior alveolar veins are formed by alveolar and dental branches of the mandible.

The _________ is a network of veins connecting the facial vein & retromandibular vein. It drains the maxillary & mandibular teeth w/ associated periodontium & gingiva, and meninges of the brain

1. Since the superior vena cava is located on the right side of the heart, the brachiocephalic veins are asymmetric.

2. The right brachiocephalic vein is shorter and vertical in placement, and the left brachiocephalic vein is longer and horizontal in placement.

1. The internal jugular vein & external jugular vein are both connected by many anastomoses.

2. Veins are usually symmetrical on each side, and are also more variable in location from person to person.
