    The 1st posterior branch off of the external carotid artery is the posterior auricular artery

    occipital artery

    Rate this question:

  • 5. 

    Both the mylohyoid artery and the mental artery are branches of the inferior alveolar artery

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because both the mylohyoid artery and the mental artery are indeed branches of the inferior alveolar artery. The inferior alveolar artery is a branch of the maxillary artery, and it supplies blood to the lower teeth, chin, and lower lip. The mylohyoid artery supplies blood to the mylohyoid muscle and the anterior belly of the digastric muscle, while the mental artery supplies blood to the chin and lower lip. Therefore, both arteries originate from the same source, making the statement true.

  • 6. 

    The infraorbital artery is the most anterior branch of the maxillary artery

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The infraorbital artery is indeed the most anterior branch of the maxillary artery. This artery supplies blood to the structures in the region of the infraorbital canal, including the lower eyelid, side of the nose, and upper lip. It is an important artery in the face and plays a crucial role in maintaining blood supply to these structures.

  • 7. 

    Veins of the face usually have the same names as the arteries that travel with them

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the veins of the face typically have the same names as the arteries that run alongside them. This is a common pattern in the human body, where veins and arteries often have similar names and travel together in pairs. This consistency in naming helps in identifying and understanding the circulatory system of the face and facilitates effective communication among medical professionals.

    • C.

      Lingual

  • 10. 

    The ________ artery supplies blood to the maxillary molers

    • A.

      Posterior superior artery

    • B.

      Pterygopalatine

    • C.

      Maxillary

    • D.

      Infraorbital

    Correct Answer
    A. Posterior superior artery
    Explanation
    The correct answer is the posterior superior artery. This artery supplies blood to the maxillary molars. The other options listed (pterygopalatine, maxillary, infraorbital) are not specifically associated with supplying blood to the maxillary molars.

    Rate this question:

  • 11. 

    After blood travels through the pulmonary veins it goes to the

    • A.

      Aorta

    • B.

      Left atrium

    • C.

      Pulmonary valve

    • D.

      Lungs

    Correct Answer
    B. Left atrium
    Explanation
    After blood travels through the pulmonary veins, it goes to the left atrium. The pulmonary veins carry oxygenated blood from the lungs back to the heart. The left atrium is one of the four chambers of the heart and receives oxygen-rich blood from the pulmonary veins. From the left atrium, the blood will then pass through the mitral valve and enter the left ventricle before being pumped out to the rest of the body through the aorta.

    A new patient come into office.  she has a large purplish bruise and some swelling under her eye and along her cheekbone area.  she states that she had a deep cavity and her dentist gave her  an injection and filled the tooth #2.  Her dentist is away on vacation and she is worried that she may have an infection.  You suspect that the lesion is:

    • A.

      The result of an assualt

    • B.

      A cavernous sinus infection

    • C.

      A hematoma

    • D.

      An allergic reaction to anesthesia

    Correct Answer
    A. The result of an assualt
    Explanation
    Based on the given information, the patient's symptoms of a large purplish bruise and swelling under her eye and along her cheekbone area suggest that the lesion is the result of an assault. This is because there is no mention of any accidental injury or any other possible causes for the bruise and swelling.

  • 13. 

    Which of the follwoing arteries supplies blood to the oral cavity

    • A.

      Lingual

    • B.

      Maxillary

    • C.

      Palatal

    • D.

      Mental

    • E.

      They all do

    Correct Answer
    E. They all do
    Explanation
    The correct answer is "they all do" because all of the listed arteries - lingual, maxillary, palatal, and mental - supply blood to the oral cavity. Each artery has a specific region within the oral cavity that it supplies blood to, ensuring that all areas receive a sufficient blood supply for proper functioning.

  • 14. 

    Which of the following are branches of the internal jugular?

    • A.

      Lingual

    • B.

      Maxillary

    • C.

      Superficial temporal

    • D.

      Facial

    • E.

      None of the above

    Correct Answer
    E. None of the above
    Explanation
    The internal jugular vein does not have any branches listed in the options provided. The internal jugular vein is a major vein that drains blood from the brain, face, and neck and usually does not have any direct branches. Instead, it receives blood from various veins in the head and neck region and then drains into the brachiocephalic vein. Therefore, none of the options listed are branches of the internal jugular vein.

    Rate this question:

  • 15. 

    The blood supply to the muscles of mastication is from the ___________ artery

    • A.

      Mental

    • B.

      Facial

    • C.

      Lingual

    • D.

      Maxillary

    • E.

      Superficial temporal

    Correct Answer
    D. Maxillary
    Explanation
    The correct answer is maxillary because it is the main artery that supplies blood to the muscles of mastication. The maxillary artery is a branch of the external carotid artery and it gives off several branches that supply blood to the muscles involved in chewing, such as the masseter, temporalis, and medial pterygoid muscles. The mental, facial, lingual, and superficial temporal arteries do not directly supply blood to the muscles of mastication.

  • 16. 

    The vein that may be injured in anesthesia of the posterior superior alveolar nerve is the

    • A.

      Retromandibular vein

    • B.

      Pterygoid plexus of veins

    • C.

      Facial vein

    • D.

      Temporal vein

    • E.

      None of the above

    Correct Answer
    B. Pterygoid plexus of veins
    Explanation
    The pterygoid plexus of veins may be injured in anesthesia of the posterior superior alveolar nerve. This is because the pterygoid plexus of veins is located in close proximity to the posterior superior alveolar nerve, which supplies sensation to the upper molars and surrounding structures. During anesthesia, if there is accidental trauma or needle penetration, it may result in injury to the pterygoid plexus of veins, leading to bleeding or hematoma formation.

    Rate this question:

  • 17. 

    If the posterior retromandibular vein is absent on one side, which of the following statement is true

    • A.

      The external jugular vein will be smaller than normal

    • B.

      The internal jugular vein will be klarger than normal

    • C.

      All blood from the maxillary will enter the common facial vein

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    If the posterior retromandibular vein is absent on one side, it means that the blood flow from that side of the face will be altered. The posterior retromandibular vein normally drains into the external jugular vein, so if it is absent, the external jugular vein will be smaller than normal. The blood that would have normally drained into the posterior retromandibular vein will now enter the common facial vein, so all blood from the maxillary will enter the common facial vein. Additionally, the internal jugular vein is not directly affected by the absence of the posterior retromandibular vein, so it will not be larger than normal. Therefore, the correct statement is "all of the above".
