How does a signal move through a neuron?
A signal moves through a neuron by traveling along the axon, which is a long, thin extension of the neuron. The signal is transmitted as an electrical impulse called an action potential. When the signal reaches the end of the axon, it triggers the release of neurotransmitters, which then carry the signal to the next neuron.
What is the small space between one neuron and the next is called?
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
How does a signal travel down a neuron and what processes are involved in its transmission?
A signal travels down a neuron through a process called neurotransmission. When a signal reaches the end of one neuron, it triggers the release of neurotransmitters into the synapse, the small gap between neurons. These neurotransmitters then bind to receptors on the next neuron, causing an electrical signal to be generated and travel down the length of the neuron. This process involves the opening and closing of ion channels, which allow ions to flow in and out of the neuron, creating an electrical impulse that travels along the neuron's axon.
How is a signal transmitted from one neuron to another in the human brain?
In the human brain, a signal is transmitted from one neuron to another through a process called synaptic transmission. When an electrical signal, known as an action potential, reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synapse, the gap between neurons. These neurotransmitters then bind to receptors on the receiving neuron, causing a new electrical signal to be generated and continue the communication between neurons.
What name is given to a neuron that is not sending a nervous impulse?
A neuron that is not sending a nervous impulse is typically referred to as a resting neuron. In its resting state, the neuron is polarized with a negative internal charge.
Why would a neuron not send an impulse?
If a neuron is not sending out an impulse or signal, this means the neuron is at rest. Neurons send signals electrochemically.
When a neuron is depolarized to threshold?
1. The neuron fires an action potential, sending the electrical signal down the axon.
If a signal from a sending neuron makes the receiving neuron more negative inside?
The receiving neuron is less likely to generate action potential.
What is an electrical signal in a neuron used to send messages in the body called?
An electrical signal in a neuron used to send messages in the body is called an action potential. This signal is generated by the flow of ions across the neuron's membrane when it reaches a certain threshold, leading to the propagation of the signal along the neuron.

What is the space between the sending and the receiving neuron called?
The space between the sending neuron's axon terminal and the receiving neuron's dendrite is called the synaptic cleft. Neurotransmitters are released into this space to transmit signals between neurons.
When one neuron wants to stimulate another it will?
A neuron releases a chemical called a neurotransmitter that will signal other neurons.
What is the term for the cell that receives a signal at a synapse?
The cell receiving the signal at the synapse is called the postsynaptic neuron.
What is the junction where the axon terminal of a sending neuron communicates with a receiving neuron?
The junction where the axon terminal of a sending neuron communicates with a receiving neuron is called a synapse. Neurotransmitters are released from the axon terminal into the synaptic cleft, where they bind to receptors on the receiving neuron, allowing for the transmission of signals between neurons.
What is the small space between one neuron and the next is called?
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
What is the message that travels through the neuron?
An Impulse
What part of a neuron carries nerve impulses away from the cell?
The axon carries the signal away from the neuron, while the dendrite carries the signal to the neuron.The cell body of a neuron (a nerve cell) receives signals from its neighbors; when prompted thereby to send a signal of it's own, the axon (an extension protruding from the body) propagates that signal electrochemically via an "ion pump" to other neurons at the terminal synapse (a small gap between one neuron and the next). At the synapse, chemicals are released into the surrounding fluid to stimulate the next neurons in the chain.The connection between neurons is called a synapse, and the sending region is normally an extended "tail" called an axon. However, in some presynaptic connections, the same sending function is done in a dendrite or soma (the bulbous end of a neuron, containing the nucleus, is called the soma or perikaryon).A good way to remember this is: "Axon and Away both start with A."
