○ lymphangioma
○ lymphadenitis
○ lymphedema
○ lymphadenopathy
question 6 (2.5 points)
in myasthenia gravis, the bodys immune system attacks the neuromuscular junction (where the neuron activates the muscle to contract). which term best describes this condition?
○ autoimmune disorder
○ allergic reaction
○ immunodeficiency disorder
○ opportunistic infection

Explanation:

First Question (Benign Tumor from Congenital Malformation)

• Lymphangioma: Benign tumor, often congenital (lymphatic malformation).
• Lymphadenitis: Inflammation of lymph nodes (not a tumor).
• Lymphedema: Swelling from lymphatic obstruction (not a tumor).
• Lymphadenopathy: Abnormal lymph node condition (not congenital tumor).

So the correct term is Lymphangioma.

• Autoimmune disorder: Immune system attacks own tissues (neuro - muscular junction in myasthenia gravis).
• Allergic reaction: Response to external allergen (not self - tissue attack).
• Immunodeficiency disorder: Weakened immune system (not attacking self).
• Opportunistic infection: Occurs in immunocompromised (not relevant here).

Myasthenia gravis is an autoimmune disorder.

Answer:

A. Lymphangioma (assuming the first option is labeled A, but based on content: Lymphangioma)
