    • C.

      Lobes of the cerebellum

    • D.

      None of the above

    Correct Answer
    B. Cerebrum and cerebellum
    Explanation
    The cerebellar tentorium is a structure in the brain that separates the cerebrum and cerebellum. It is a fold of the dura mater, the outermost layer of the meninges, and it helps to provide support and protection to the brain. The cerebrum is responsible for higher cognitive functions, such as thinking, reasoning, and memory, while the cerebellum is involved in coordination, balance, and motor control. Therefore, the correct answer is cerebrum and cerebellum.

    Blood flow out of the cerebrum is facilliated by

    • A.

      The dural venous sinuses

    • B.

      The great vein of galen

    • C.

      All of the above

    • D.

      None of the above

    Correct Answer
    C. All of the above
    Explanation
    Blood flow out of the cerebrum is facilitated by the dural venous sinuses and the great vein of Galen. The dural venous sinuses are a network of veins located between the two layers of the dura mater, the outermost membrane covering the brain. These sinuses collect deoxygenated blood from the brain and drain it into the internal jugular veins, which eventually carry the blood back to the heart. The great vein of Galen is a large vein located deep within the brain that also helps drain blood from the cerebrum. Therefore, both the dural venous sinuses and the great vein of Galen play a role in facilitating blood flow out of the cerebrum.

      Choroid

    • B.

      Retina

    • C.

      Ciliary body

    • D.

      Iris

    Correct Answer
    B. Retina
    Explanation
    The vascular layer of the eye, also known as the uvea, is responsible for supplying blood to the various structures of the eye. It consists of three main parts: the choroid, ciliary body, and iris. The choroid provides nourishment to the retina, which is the innermost layer of the eye responsible for sensing light and transmitting visual information to the brain. Therefore, the correct answer is retina, as it is not a part of the vascular layer of the eye.

    • C.

      Tympanic plexus of nerves

    • D.

      Malleus, incus, stapes

    • E.

      None of the above

    Correct Answer
    E. None of the above
    Explanation
    The correct answer is "none of the above." This is because the question is asking about the involvement of certain structures in problems related to the external ear, and none of the options listed (vestibulocochlear organ, endolymph, tympanic plexus of nerves, malleus, incus, stapes) are directly associated with the external ear. The vestibulocochlear organ is responsible for hearing and balance, the endolymph is a fluid found in the inner ear, the tympanic plexus of nerves is associated with the middle ear, and the malleus, incus, and stapes are the three small bones in the middle ear. Therefore, none of these options are involved in problems related to the external ear.

    • C.

      A hoarse voice

    • D.

      A & B

    • E.

      All of the above

    Correct Answer
    B. Impaired function of CN XI
    Explanation
    A patient with pain in the lateral cervical region may have impaired function of CN XI. The question mentions that the lateral cervical region is bordered by the SCM (sternocleidomastoid muscle) and the border of the trapezius. CN XI, also known as the accessory nerve, innervates both of these muscles. Therefore, if there is pain in this region, it could potentially affect the function of CN XI and lead to impaired movement of the SCM and trapezius muscles.

  • 27. 

    Which nerve passes deep to the digastric muscle and enters the submandibular region

    • A.

      Phrenic nerve

    • B.

      Hypoglossal (CN XII)

    • C.

      Trigeminal ( CN V)

    • D.

      None of the abvoe

    Correct Answer
    B. Hypoglossal (CN XII)
    Explanation
    The hypoglossal nerve (CN XII) passes deep to the digastric muscle and enters the submandibular region. This nerve is responsible for controlling the movements of the tongue, including swallowing and speech. It also provides sensory information from the tongue. The phrenic nerve is not relevant to the submandibular region, as it innervates the diaphragm. The trigeminal nerve (CN V) is responsible for sensory information from the face, but it does not pass deep to the digastric muscle. Therefore, the correct answer is hypoglossal (CN XII).

      Damage to reccurent laryngeal nerve

    • D.

      Impairment of the phrenic nerve

    • E.

      None of the above

    Correct Answer
    C. Damage to reccurent laryngeal nerve
    Explanation
    Damage to the recurrent laryngeal nerve is the most likely cause of a hoarse voice after surgery of the neck. The recurrent laryngeal nerve innervates the muscles responsible for vocal cord movement. Injury to this nerve can result in vocal cord paralysis or dysfunction, leading to hoarseness. The other options, such as injury of the hypoglossal nerve, trauma of the vagus nerve, or impairment of the phrenic nerve, do not directly affect the vocal cords and are less likely to cause hoarseness.

    Female breasts enlarge during puberty because of

    • A.

      Glandular development

    • B.

      Fat deposition

    • C.

      All of the above

    • D.

      None of the above

    Correct Answer
    C. All of the above
    Explanation
    During puberty, female breasts enlarge due to glandular development and fat deposition. Glandular development refers to the growth and development of the milk-producing glands in the breasts, which is stimulated by hormonal changes. At the same time, fat deposition occurs in the breasts, leading to an increase in size. Both processes contribute to the enlargement of female breasts during puberty, making the answer "all of the above" correct.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the visceral pleura is a thin membrane that covers the surface of the lungs and is tightly adhered to it. It cannot be easily separated or dissected from the lungs without causing damage. The visceral pleura and the lungs are closely connected and function together to protect and support the lungs during breathing.

    The right main bronchi is a common site of obstruction in the lung while the left main bronchi is a site of obstruction in the esophagus

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the right main bronchus is wider, shorter, and more vertical than the left main bronchus. This anatomical difference makes the right main bronchus more prone to obstruction by foreign objects or mucus, leading to conditions like aspiration pneumonia. On the other hand, the left main bronchus is narrower and more horizontal, making it less likely to be obstructed. However, it is important to note that both main bronchi can be sites of obstruction, but the right main bronchus is more commonly affected.

    The main bronchi diverge immediately into

    • A.

      Lobar bronchi

    • B.

      Segmental bronchi

    • C.

      None of the above

    Correct Answer
    A. Lobar bronchi
    Explanation
    The main bronchi, also known as primary bronchi, are the first branches of the trachea that enter the lungs. They further divide into smaller bronchi called lobar bronchi. Lobar bronchi are responsible for supplying air to each lobe of the lungs. On the other hand, segmental bronchi are the smaller branches that arise from the lobar bronchi and supply air to specific segments within each lobe. Therefore, the correct answer is lobar bronchi.

    Pulmonary arteries carry venous blood and veins carry arterial blood

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because pulmonary arteries carry deoxygenated blood from the heart to the lungs, where it picks up oxygen, while veins carry oxygenated blood from the lungs back to the heart. This is the opposite of what happens in the systemic circulation, where arteries carry oxygenated blood away from the heart and veins carry deoxygenated blood back to the heart.
