Nerve Physiology: __________________ Action Potential Generation: Nerve cells, or neurons, communicate through action potentials, which are rapid changes in membrane potential. This process involves depolarization, repolarization, and hyperpolarization phases, mediated by ion channels such as sodium (Na+), potassium (K+), and voltage-gated channels. Synaptic Transmission: Nerve impulses are transmitted across synapses, where neurotransmitters released from the presynaptic neuron bind to receptors on the postsynaptic neuron, leading to depolarization or inhibition of the postsynaptic membrane. Muscle Physiology: ___________________ Muscle Contraction: Skeletal muscle contraction occurs through the sliding filament theory, where actin and myosin filaments overlap and slide past each other, powered by the hydrolysis of ATP. Neuromuscular Junction (NMJ): Motor neurons release acetylcholine (ACh) at the NMJ, which binds to receptors on the muscle fiber, initiating depolarization and leading to muscle contraction. Excitation-Contraction Coupling: The depolarization of the muscle fiber triggers the release of calcium ions (Ca2+) from the sarcoplasmic reticulum, which bind to troponin, initiating the cross-bridge cycle and muscle contraction. Clinical Correlations: ___________________ Neuromuscular Disorders: Conditions like myasthenia gravis, Lambert-Eaton syndrome, and muscular dystrophies involve abnormalities in neuromuscular transmission or muscle function, affecting strength, tone, and coordination. Electromyography (EMG): EMG is a diagnostic tool used to assess the electrical activity of muscles and nerves, aiding in the diagnosis of neuromuscular disorders. Key Concepts for Exams: _________________________ Understand the events of action potential generation and synaptic transmission. Grasp the mechanism of muscle contraction and the role of calcium ions in excitation-contraction coupling. Recognize common neuromuscular disorders and their clinical presentations for diagnostic evaluation. Familiarize yourself with the principles of EMG and its application in clinical practice. This rapid revision of nerve and muscle physiology provides a concise overview of essential concepts vital for success in NEET PG, FMGE, and USMLE exams, ensuring a solid foundation in neurophysiology. 📚💪 #neetpg #FMGE #USMLE #Physiology #NervePhysiology #MusclePhysiology #MedicalEducation #RapidRevision #Neuroscience #MedicalStudents #StudyTips #MedTwitter #fmge #fmgevideos #rapidrevisionfmge #fmgejan2023 #mbbslectures #nationalexitexam #nationalexittest #neetpg #usmlepreparation #usmlestep1 #fmge #usmle #drgbhanuprakash #medicalstudents #medicalstudent #medicalcollege #neetpg2023 #usmleprep #usmlevideos #usmlestep1videos #medicalstudents #neetpgvideos #nervephysiology #musclephysiology #generalphysiology
