(select all that apply) The action potential moves down the axon and a synapse is between neurons. The synapse travels long distances and the action potential can only travel short distances. The action potential starts at the dendrites and the synapse starts at the ахon. The action potential is always the same and the synaptic potentials vary. the action potential involves only the postsynaptic neuron, but the synapse involves both the pre- and post-synaptic neurons.
- Summarize the steps in generating an action potential as a flowchart. You can make your flowchart on paper and take a picture of it, or make it electronically. Be sure you’ve included: the location in the neuron and components of the neuron involved, the types of cellular transport and ions involved, how action potentials can be stimulated and inhibited. you can get the information from this: https://youtu.be/HYLyhXRp298match the letters to the correct terms using the figure synaptic vesicle neurotransmitter pre-synaptic neuron post-synaptic neuron neurotransmitter receptorREAD: They key to large-scale communication in the entire nervous system is the ability to pass nerve impulses on a small scale from one neuron to the next so that signals can be transmitted throughout the entire body. The junction between two neurons is called a synapse, and is the critical space that mediates the transfer of a signal from the presynaptic neuron (the sender) to the postsynaptic neuron (the receiver) or even an effector cell (like a gland or muscle cell.) You circled a synapse in Model 1. Synapses can be electrical or chemical. Electrical synapses transmit electrical signals via gap junctions. A channel protein connects the cytoplasm of two adjacent neurons so that ions can flow directly from one cell to another to pass on the signal. However, the most common type of synapse is a chemical synapse. These utilize chemical signals, called neurotransmitters, to transmit the signal across the synaptic cleft. This is a slower process, but allows for much greater precision…

Edit View Insert Format Tools Table Paragraph BIUA 12pt v ...Part One: The story begins with Synapse Action potential travels down the axon and reaches the synaptic bulb. _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ Acetylcholine (ACH) diffuses across the synaptic cleft and binds to receptors. Calcium rushes into pre-synaptic terminal and initiates exocytosis. Electric current from action potential open up voltage gated calcium channels. ACH receptors open the associated gated channels (Na+ gated channels) Na+ rushes through the open channels into the muscle cell causing a large depolarization. Neurotransmitter (from the synaptic vesicles) is released into the cleft. After the initial depolarization of the muscle cell, the muscle cell releases Acetylcholinesterase (ACHE). The electric current in the T-tubules shocks the sarcoplasmic reticulum (opening voltage gated calcium channels) and causes calcium to spill into the cytoplasm of the muscle cell. ACHE begins to destroy the ACH in the synaptic cleft. The wave of…Synapses through interconnected neurons are known to be a junction that mediates information transfer from one neuron to the other neurons.
