    Refer to the figure below of a CTA of intracranial and extracranial arteries. Which arrow points to the internal carotid artery

    • A.

      E

    Correct Answer
    B. B
    Explanation
    In the figure, the arrow labeled "B" points to the internal carotid artery. This can be determined by comparing the anatomical structures and their locations in the image. The internal carotid artery is a major blood vessel that supplies blood to the brain and is located in close proximity to the external carotid artery (labeled "A" in the figure). By identifying the external carotid artery, we can determine that the arrow labeled "B" points to the internal carotid artery.

  • 13. 

    Which vein drains blood from the lateral region of the face?

    • A.

      Retromandibular

    • B.

      Internal jugular

    • C.

      External jugular

    • D.

      Anterior jugular

    Correct Answer
    A. Retromandibular
    Explanation
    The retromandibular vein drains blood from the lateral region of the face. It is located behind the mandible and is formed by the union of the superficial temporal vein and the maxillary vein. It then joins with the posterior auricular vein to form the external jugular vein, which ultimately drains into the subclavian vein. The internal jugular vein drains blood from the brain and deep structures of the face and neck. The external jugular vein drains blood from the superficial structures of the face and neck. The anterior jugular vein drains blood from the anterior part of the neck.

    The sinoatrial (SA) node is located in the:

    • A.

      Interatrial se3ptum near the coronary sinus

    • B.

      Interventricular septum near the coronary sinus

    • C.

      Superior aspect of the left atrium

    • D.

      Superior aspect of the right atrium

    Correct Answer
    D. Superior aspect of the right atrium
    Explanation
    The SA node is located in the superior aspect of the right atrium. This is where the electrical impulses that initiate the heartbeat originate. The SA node acts as the natural pacemaker of the heart, sending electrical signals to the atria and causing them to contract. From there, the impulses travel through the atrioventricular (AV) node and into the ventricles, causing them to contract as well. The location of the SA node in the right atrium allows for efficient coordination of the heart's pumping action.

  • 15. 

    Which vessel is the most posterior vessel arising from the arch of the aorta

    • A.

      Brachiocephalic trunk

    • B.

      Right common carotid artery

    • C.

      Right subclavian artery

    • D.

      Left subclavian artery

    Correct Answer
    D. Left subclavian artery
    Explanation
    The left subclavian artery is the most posterior vessel arising from the arch of the aorta. It branches off from the aorta and supplies blood to the left arm and some structures in the head and neck. The brachiocephalic trunk, right common carotid artery, and right subclavian artery are also branches of the aorta, but they are not as posterior as the left subclavian artery.

    Refer to the figure below of a midsagittal, T2- weighted MRI of the cervical spine with spinal ligaments. Which arrow points to the ligamentum nuchae

    • A.

      A

    • B.

      B

    • C.

      C

    • D.

      D

    Correct Answer
    C. C
    Explanation
    The ligamentum nuchae is a fibrous band that runs along the back of the neck and connects the base of the skull to the spinous processes of the cervical vertebrae. In the given MRI image, arrow C points to a structure that appears to be in the correct location for the ligamentum nuchae. The ligamentum nuchae is a thickening of the supraspinous ligament in the cervical region, and it is visible as a dark band in the midline of the image.

    The term for the anterior fontanel is the:

    • A.

      Asterion

    • B.

      Pterion

    • C.

      Bregma

    • D.

      Lamboda

    Correct Answer
    C. Bregma
    Explanation
    The correct answer is "bregma." The bregma is the anatomical term used to describe the junction between the sagittal and coronal sutures of the skull. It is located at the anterior fontanelle, which is a soft spot in the baby's skull where the bones have not yet fully fused. The anterior fontanelle allows for the growth and expansion of the baby's brain during development.
