  • 2. 

    When performing surgery on the parotid gland, which of the following cranial nerves could be lacerated? 

    • CN V3

    • CN V2

    • CN 7

    • CN 5

    Correct Answer
    A. CN 7
    Explanation
    During surgery on the parotid gland, there is a possibility of lacerating the cranial nerve 7 (CN 7). This nerve, also known as the facial nerve, is responsible for controlling the muscles of facial expression. It also carries taste sensations from the anterior two-thirds of the tongue. Laceration of CN 7 can lead to facial weakness or paralysis, loss of taste sensation, and difficulty with facial expressions. Therefore, it is important for surgeons to be cautious and aware of the location of CN 7 during parotid gland surgery to minimize the risk of injury.

    Which muscle attaches to the coronoid process?

    • Masseter

    • Lateral Pterygoid

    • Sternocleidomastoid

    • Temporalis

    Correct Answer
    A. Temporalis
    Explanation
    The temporalis muscle attaches to the coronoid process. The coronoid process is a bony projection on the mandible (lower jaw) that serves as an attachment site for various muscles involved in chewing and jaw movement. The temporalis muscle is one of the primary muscles responsible for closing the jaw during chewing, and it originates from the temporal bone of the skull and inserts onto the coronoid process.

    Which of the following muscles protrude the temporomandibular joint?

    • Masseter, temporalis

    • Lateral pterygoid, medial pterygoid

    • Temporalis, masseter, medial pterygoid

    • Digastric, geniohyoid, mylohyoid

    Correct Answer
    A. Lateral pterygoid, medial pterygoid
    Explanation
    The correct answer is lateral pterygoid, medial pterygoid. These two muscles are responsible for protruding the temporomandibular joint. The lateral pterygoid muscle helps to move the mandible forward and sideways, while the medial pterygoid muscle aids in closing the jaw and moving it forward. Together, these muscles play a crucial role in the movement and function of the temporomandibular joint.

    The parasympathetic pathway for the submandibular and sublingual glands are innervated by_________ at the ________ ganglion. 

    • CN 7, otic

    • CN 9, otic

    • CN 5, submandibular

    • CN 7, submandibular

    Correct Answer
    A. CN 7, submandibular
    Explanation

  • 6. 

    The parasympathetic pathway for the parotid gland is innervated by ______ at the _______ ganglion. 

    • CN 7, otic

    • CN 7, pterygopalatine

    • CN V, pterygopalatine

    • CN 9, otic

    Correct Answer
    A. CN 9, otic
    Explanation
    The parasympathetic pathway for the parotid gland is innervated by CN 9 at the otic ganglion.

    Rate this question:

  • 7. 

    Which of the following are located at C6? (Select 3)

    • Bifurcation of common carotid

    • Vertebral Artery

    • Esophagus upper limit

    • Cricoid cartilage

    • Upper boarder of thyroid cartilage

    Correct Answer(s)
    A. Vertebral Artery
    A. Esophagus upper limit
    A. Cricoid cartilage
    Explanation
    The vertebral artery is located at C6 as it enters the transverse foramen of the sixth cervical vertebra. The esophagus upper limit is also located at C6 as it passes through the thoracic inlet and enters the abdomen. The cricoid cartilage is located at C6 as it is the only complete ring of cartilage in the trachea and is found at the level of the sixth cervical vertebra. The other options, bifurcation of common carotid and upper border of thyroid cartilage, are not located at C6.

    • CN 7, C2, C3

    Correct Answer
    A. C2, C3, V3
    Explanation
    the parasympathetic pathway is innervated by CN 9,

    • True

    • False

    Correct Answer
    A. False
    Explanation
