Question

Write a step-by-step explanation of how a signal travels from the synapse of one end of a neuron to the other end of a neuron. Include the names of the neuron parts to properly describe the pathway of the electrochemical signal.

Answer 1

Explanation:

Within 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 released. The space between the axon terminal of one cell and the dendrites of the next is called the synapse.....

Answer 2

Answer:

The parts of neurons are dendrites, cell body, nucleus, axon, axon terminal, synaptic bulbs.

Explanation:

• The dendrites take the signal from another neuron and pass it to the cell body.
• the cell body, travels down the axon, and terminates at the axon terminal.
• Axon terminals have vesicles filled with releasable neurotransmitters.
• When neurons communicate, neurotransmitters are released from one of her neurons, cross the synapse, and bind to specialized molecules in the next neuron called receptors.
• Receptors receive messages, process them, and send them to the next neuron.
• When nerve impulses reach dendrites at the ends of axons, chemical messengers called neurotransmitters are released.
• The neurotransmitters are released into the synapse.
• The chemical binds to a receptor molecule on the membrane of the second neuron.
