Question

question 67
osteoarthritis is:
bilateral joint inflammation
inflammation of bone with ligament swelling
inflamed bone and cartilage causing swelling
inflammation of a bone joint causing bone hypertrophy

question 68
the epstein-barr virus causes a disease whose literal name is \one/nut or kernel.\ this disease is:
malaria
mononucleosis
rheumatic fever
trypanosomiasis

question 69
the nerve in the eye that carries visual impulses from the retina to the brain is the:
trochlear
optic
oculomotor
olfactory

Explanation:

• Question 67: Osteoarthritis is characterized by inflammation of a bone joint which can lead to bone hypertrophy. It is not just bilateral joint inflammation (as other joint - related conditions can also have bilateral involvement), not inflammation of bone with ligament swelling (which is more related to other ligament - bone disorders), and not just inflamed bone and cartilage causing swelling (the key aspect is the joint inflammation and its effect on bone).
• Question 68: The Epstein - Barr virus is the causative agent of mononucleosis. Malaria is caused by Plasmodium parasites, rheumatic fever is often related to streptococcal infections, and trypanosomiasis is caused by Trypanosoma parasites. The root “mono -” (one) and “nucleo -” (nucleus) in mononucleosis aligns with the description.
• Question 69: The optic nerve is responsible for carrying visual impulses from the retina to the brain. The trochlear nerve is involved in eye movement (specifically the superior oblique muscle), the oculomotor nerve is also involved in multiple eye - movement functions (such as controlling most of the extra - ocular muscles), and the olfactory nerve is related to the sense of smell.

Answer:

• Question 67: inflammation of a bone joint causing bone hypertrophy
• Question 68: mononucleosis
• Question 69: optic
