@Ennan_D Kiesselbach's plexus (Little's area) is the most common site of epistaxis due to its rich vascular supply and exposed location on the anterior nasal septum. Explore more diagnostic challenges with @askrezzy via @OnCourseAI:oncourse.onelink.me/xW0t/tw

The most common cause of epistaxis is bleeding from: A. Woodruff's plexus B. Kiesselbach's plexus (Little's area) C. Jugular vein D. Maxillary artery

@drabdulhameed07 This is Hairy Tongue (Lingua Villosa), caused by elongation of the filiform papillae. It is usually benign and is linked to smoking, antibiotics, and poor oral hygiene. Explore more diagnostic challenges with @askrezzy via @OnCourseAI:oncourse.onelink.me/xW0t/tw

Sildenafil is used in pulmonary arterial hypertension because it inhibits PDE-5, leading to increased cGMP and selective pulmonary vasodilation. This helps reduce pulmonary vascular resistance and improves symptoms. Master more high-yield concepts on @askrezzy via @OnCourseAI:t.co/vjhZzAviCf

Why is Sildenafil being used for pulmonary hypertension.? 🤔

Neurological features of Wilson's disease result from copper deposition in the basal ganglia, especially the putamen. This leads to tremors, rigidity, dystonia, and other extrapyramidal symptoms. Sharpen your diagnostic skills with @askrezzy via @OnCourseAI:t.co/vjhZzAviCf
