Description

Note: These are handwritten notes. Questions and answers on the following topics: Resting membrane potential Graded potentials Development of action potential Absolute refractory period and relative refractory period synapses Chemical synaptic transmission Neurotransmitters Inhibition and excitations - synapses Temporal and spatial summation of graded potentials Convergence and divergence in a neural circuit Synaptic transmission interruption Muscle structures and components and their role in muscle contraction Somatic nervous system and neuromuscular junction Sliding filament mechanism and power stroke excitation-contraction coupling contraction, power stroke and relaxation process (+ role of ATP) Modulate the force of skeletal muscle contraction - twitch summation, motor unit recruitment and tetanus Skeletal muscle fibres Smooth and cardiac muscle (differences to skeletal muscle) Cardiac action potential sensory receptor types neural coding for modality, intensity, timing and location of sensory input receptors and sensation in the somatosensory system
