WebWithin a cell, action potentials are triggered at the cell body, travel down the axon, and end at the axon terminal. The axon terminal has vesicles filled with neurotransmitters ready to be … WebApr 5, 2024 · It is important to note that the action potential is an all-or-nothing process and that signals are not partially transmitted. The neurons either fire or they do not. Axon The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal. cuberdon carrefour

12.5 The Action Potential – Anatomy & Physiology

WebThe brain distinguishes sensory stimuli through a sensory pathway: action potentials from sensory receptors travel along neurons that are dedicated to a particular stimulus. These neurons are dedicated to that particular stimulus and synapse with particular neurons in the brain or spinal cord. WebScience Biology Biology questions and answers T/F The gray matter, or axons of neurons, within the brain’s cortex processes incoming information associated with the different stimuli, while the white matter, or cell bodies, found in the center of the brain transmits action potentials between different regions of the CNS. WebAt any given moment, a neuron may receive postsynaptic potentials from thousands of other neurons.
