What is an excitable nerve cell that sends electrical signals?
A neuron is an excitable nerve cell that sends electrical signals when stimulated
When the nerve cell is stimulated what is it called?
When a nerve cell is stimulated, the process is called depolarization. This occurs when the cell membrane's potential becomes less negative, leading to the generation of an action potential if the threshold is reached. The action potential then propagates along the nerve fiber, allowing for the transmission of signals.
What causes the electrical charge in the nerve?
The electrical charge in nerves is caused by the movement of ions, such as sodium and potassium, across the nerve cell membrane. This movement creates a difference in electrical charge between the inside and outside of the cell, known as the membrane potential. When a nerve is stimulated, this membrane potential changes, allowing for the transmission of electrical signals along the nerve cell.
What is the space through which a nerve impulse passes from one nerve cell to another called?
The space through which a nerve impulse passes from one nerve cell to another is called a synapse. It is a small gap between neurons where neurotransmitters are released to transmit signals between the cells.
What happens when a neuron is stimulated by another neuron?
When a neuron is stimulated by another neuron, an action potential is generated and travels down the axon of the stimulated neuron. This action potential triggers the release of neurotransmitters at the synapse, which then binds to receptors on the postsynaptic neuron, leading to either excitation or inhibition of the postsynaptic neuron.

How is a resting potential achieved in the nervous system?
The resting nerve cell is not being stimulated to send a nerve impulse
What is another name for Nerve Cells?
Neuron is another name for a nerve cell.
What are the chemicals called that a nerve cell uses to communicate with another nerve cell or muscle cell?
Neurotransmitters
What is another for a nerve cell?
Neurons are another word for nerve cells https://faculty.washington.edu/chudler/nsdivide.html
Another name for nerve cell?
Nerve cells are called neurons.
What is the location from which a nerve impulse is transmitted from one nerve cell to another?
synapse
What events occur in a neuron between the stimulus of a nerve and the stimulation of its target cell?
When a nerve is stimulated, its cell membrane is depolarised so that the inside of the cell becomes less negative. The potential is conducted along the axon to the axon terminal. At the dendrite it stimulates the release of a chemical transmitter, which diffuses across a synapse. The transmitter binds to receptor sites on the postsynaptic cell membrane to stimulate the generation of another impulse.
Which cell contracts when stimulated by nerve impulses?
Muscle cells contract when stimulated by nerve impulses. Specifically, in skeletal muscle, motor neurons release neurotransmitters at the neuromuscular junction, triggering an action potential in the muscle cell. This leads to the release of calcium ions, which facilitate the interaction between actin and myosin filaments, resulting in muscle contraction.
