C Correct answer
Explanation

Tick-borne encephalitis (TBE) is a viral infectious disease involving the central nervous system. The disease most often manifests as meningitis, encephalitis, or meningoencephalitis. Although TBE is most commonly recognized as a neurological disorder, mild fever can also occur.

Multiple choice

Among the following viral diseases ___________ is an inflammation of the covering on the brain and spinal cord.

  1. Molluscum Contagiosum

  2. Viral meningitis

  3. Mononucleosis

  4. Roseola infantum

B Correct answer
Explanation

Viral meningitis, also known as aseptic or non-bacterial meningitis, is an inflammation of the covering on the brain and spinal cord. The most common viral source is the enteroviruses, or common intestinal viruses, group. Direct contact with an infected person through respiratory secretions or fecal material is the main source of spreading of viral meningitis.

Multiple choice

The term 'bag of worms' is associated with the damage of

  1. glossopharyngeal nerve

  2. vestibulocochlear nerve

  3. facial nerve

  4. hypoglossal nerve

  5. oculomotor nerve
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The hypoglossal nerve (XII) is unique as it is innervated bilaterally from both hemispheres of motor cortex. Damage to the oculomotor nerve (III) can cause double vision (diplopia) with lateral strabismus, ptosis and mydriasis.

Multiple choice

Inflammation of the brain is known as ______.

  1. peritonitis

  2. gastritis

  3. encephalitis

  4. folliculitis

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Encephalitis is inflammation of the brain parenchyma, often caused by viral infections. The prefix 'encephalon' refers to the brain and '-itis' indicates inflammation. Peritonitis is abdominal lining inflammation, gastritis is stomach inflammation, and folliculitis is hair follicle inflammation.

Multiple choice

Why do herpes virus infections recur?

  1. The virus is incapable of penetrating latex.

  2. The virus spreads first to autonomic nerves and then to the nerve root ganglia where it remains dormant for indeterminate periods of time.

  3. Primary HHV-6B infection usually occurs in adults and is the most common cause of fever-induced seizures.

  4. The virus remains dormant in the infected mucosal and skin cells for indeterminate periods of time.

  5. The virus inserts its DNA into host cell DNA and immortalises the cells.
