Nervous system order of events
WebA triggering event occurs that depolarizes the cell body. This signal comes from other cells connecting to the neuron, and it causes positively charged ions to flow into the cell body. Positive ions still flow into the cell to depolarize it, but these ions pass through channels that open when a specific chemical, known as a neurotransmitter, binds to the channel and … WebAug 21, 2016 · Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ is the correct order of general reflex arc. Reflex arc starts with a stimulus. The stimulus must be sufficiently strong to initiate impulse in sensory neuron. Sensory neuron carries the impulse to intermediary neuron. Intermediary neuron carries the impulse to …

WebJan 17, 2024 · Action potential is a brief reversal of membrane potential in which the membrane potential changes from -70mV to +30mV. The action potential has three main stages: depolarization, repolarization, and hyperpolarization. Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated …
WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal. WebThe central nervous system (CNS), which is the brain and the spinal cord. This coordinates a response and sends a signal down a motor neuron. Motor neurons:
