HPV (human papillomavirus) is likely to involve the mucous membranes, epithelial tissues of genitalia, anus, mouth, and throat where viral infection establishes.
A) skull and spine
Skull and spine constitute bony structures, skeletal elements unrelated to HPV's epithelial tropism. HPV infects soft tissues, not bone.
B) mucous membranes
Mucous membranes precisely match HPV's infection sites: stratified squamous epithelium of cervix, vulva, penis, anus, and oropharynx where viral replication occurs. HPV's oncogenic potential manifests in these mucosal tissues, making this the anatomically accurate answer.
C) kidneys
Kidneys are filtration organs, urinary system structures unrelated to HPV pathogenesis. No established HPV-kidney disease relationship exists.
D) heart
Heart is muscular pump, cardiovascular organ unaffected by HPV. Viral tropism targets epithelial, not cardiac, tissue.
Conclusion
HPV exhibits epithelial tropism targeting mucous membranes, distinct from skeletal, renal, or cardiac systems. Mucous membranes alone captures HPV's essential infection sites: genital, anal, and oropharyngeal epithelia where viral replication and oncogenesis occur.
Topic Flashcards
Click to FlipWhat type of body tissue—such as the lining of the cervix, throat, or anus—is the primary target for Human Papillomavirus (HPV) infection?
Mucosal epithelium or mucous membranes
HPV is the primary cause of most cancers occurring in which specific female reproductive organ?
The cervix.
True or False: The most common route of HPV transmission is through contact with infected blood.
False. It is primarily transmitted through direct skin-to-skin or mucosal contact.
Which preventative medical intervention is most effective against the strains of HPV that cause cervical cancer?
The HPV vaccine.
Besides the cervix, name another location in the body where HPV can cause warts or precancerous changes.
The oropharynx (throat/tonsils), anus, or external genitals.
