USMLE Step 1 || Nervous System (Anatomy and Physiology) Lecture 2 (First Aid Only) بالعربي

💡In this video, I break down two crucial concepts in neuroscience: neuron action potentials and sensory receptors. 📌Learn about the key stages of the action potential, from resting potential to depolarization, repolarization, and hyperpolarization, with an easy-to-follow graph and explanation. ✅ Explore how sodium (Na⁺) and potassium (K⁺) channels work to create electrical signals in neurons. ✅ Discover the different types of sensory receptors (e.g., free nerve endings, Meissner corpuscles, Pacinian corpuscles) and their functions in detecting stimuli like touch, temperature, pressure, and vibration. 💡 This video is essential for those studying neuroanatomy, preparing for exams like the USMLE, or gaining a deeper understanding of nervous system pathology and physiology. 👉 Don’t forget to like, share, and subscribe for more medical education content! للانضمام الى كورس التحضير للمعادلة الاميريكية(First Aid Only): https://drhebatutoring.com/courses-ar... للانضمام الى الكورس التاسيسي في المعادلة الامريكية: https://drhebatutoring.com/courses-ar... ولمعرفة المزيد من المعلومات حول اختبار المعادلة الاميريكة واهم النصائح حول كيفية اجتياز الاختبار :   / dr.hebatutoring   وللانضمام الى جروب الدراسة المجاني للمعادلة الامريكية: https://t.me/drhebastudygroup
