What term is used to describe a neuron that is not transmitting a signal?
When a neuron is not transmitting a signal, it is at rest.

The most common form of communication between neurons is?
The most common form of communication between neurons is through neurotransmitters. These are chemicals released by one neuron that travel across the synaptic gap to bind to receptors on another neuron, transmitting signals between them.
What can excite a neuron or stop it from transmitting?
Excitatory signals, such as neurotransmitters like glutamate, can stimulate a neuron to transmit an electrical impulse. Inhibitory signals, like neurotransmitters GABA, can prevent a neuron from transmitting by hyperpolarizing the cell membrane and decreasing the likelihood of an action potential.
What happens at a synapses?
At a synapse, one neuron sends signals to another neuron through the release of chemicals called neurotransmitters. These neurotransmitters travel across the synapse and bind to receptors on the receiving neuron, which can either excite or inhibit the next neuron's activity. This communication between neurons plays a crucial role in transmitting information throughout the nervous system.
What is the name of the cells that support the transmitting cells of neuron?
neuroglia (glial cells) - approx 9 glia per 1 neuron
Message sent by releasing chemicals that jump across synapses involve?
Messages sent by releasing chemicals that jump across synapses involve the release of neurotransmitters from the presynaptic neuron. These neurotransmitters then travel across the synaptic gap and bind to specific receptors on the postsynaptic neuron, altering its electrical potential and transmitting the message. This process is essential for communication between neurons in the nervous system.
What is the name of the gap between the transmitting and receiving neuron in a chemical synapse?
synaptic cleft
What are extensions of a neuron that receive signals?
Dendrites are the extensions of a neuron that receive signals from other neurons. They are responsible for transmitting electrical impulses towards the cell body of the neuron.
What does axon terminal of motor neuron release?
The axon terminal of a motor neuron releases the neurotransmitter acetylcholine. Acetylcholine is responsible for transmitting signals from the motor neuron to muscle fibers, leading to muscle contractions.
Where are neurotransmitters released?
Neurotransmitters are released from the axon terminal of a neuron into the synaptic cleft, which is the small gap between the axon terminal and the dendrite of a neighboring neuron. neurotransmitters then bind to receptors on the receiving neuron, transmitting the signal.
What does neurone mean?
The definition of the word neuron is "a specialized cell transmitting nerve impulses; a nerve cell."
