WebPart A - Separation of Charges Across the Membrane of a Resting Neuron A resting neuron is an unstimulated neuron that is not presently generating an action potential. The resting membrane potential is the separation of the relative positive and negative charges across the membrane of a cell at rest. WebMar 6, 2024 · Ligand-gated ion channels (LGICs) are transmembrane proteins which open to selectively allow ions such as Na+, K+, Ca++, or Cl− to pass through the membrane in response to the binding of a ligand messenger. Sound waves cause mechanical deformation of hair cells in the ear. harley davidson baby clothes clearance

WebA stimulus from a sensory cell or another neuron depolarizes the target neuron to its threshold potential (−55 mV). Na + channels in the axon hillock open, allowing positive ions to enter the cell (Figure 1). Once the sodium channels open, the neuron completely depolarizes to a membrane potential of about +40 mV. Web1. Na channels inactivate and voltage-gated K+ channels activate, allowing K+ to flow out of the axon, and repolarization begins. 2. An unstimulated neuron has a negative resting membrane potential. 3. The axolemma returns to resting membrane potential. 4. Voltage-gated Nat channels open 6 of 18 Show transcribed image text Expert Answer WebAug 13, 2024 · The formation of an action potential can be divided into five steps: (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached, all Na+ channels open and the membrane depolarizes. harley davidson axle size chart
