When nerve cells or neurons are stimulated they undergo chemical changes which make little waves of electricity or nerve impulses. These are based mainly on the movement of positively charged sodium and potassium ions through the neurons cell membrane.When the impulses reach a junction-synapse-they trigger the release of chemicals called neurotransmitters. These then cross the synapse and stimulate the receiving neuron to fire impules of their own.
Dendrites collect nerve impulses and Axons convey impulses away from cell.

The cells that transmit nerve impluses in the nervous system are?
The cells that transmit nerve impluses in the nervous system are neurons.
What cells process and transmit most chemical signals?
Neurons
Nervous tissue contains specialized cells called?
Neurons are the conducting cells of nerve tissue. The neurons transmit the electrical charges and chemical signals via the synapses.
Neurons transmit signals acrossed a?
Neurons transmit signals across a synapse
These neurons bring messages into the nervous system?
Well not messages but electrical impluses which the brain can interpret.
What carries impluses towards the brain and spinal cord?
The sensory neurons carry impulses through the spinal cord to the brain.
Chemical communication is carried out between neurons by substances called?
neurotransmitters. These are chemical messengers that transmit signals across synapses, which are junctions between neurons. Neurotransmitters play a crucial role in regulating various physiological processes in the brain and body.
What is the space between neurons across which chemical messages pass?
The space between neurons is called the synaptic cleft. It is where neurotransmitters are released by the presynaptic neuron, travel across the cleft, and bind to receptors on the postsynaptic neuron to transmit chemical messages.
What is the bundle of nerve fibers that send messages to the brain which interprets them?
The nerves that carry impulses toward the brain are called efferent nerves. Afferent nerves carry impulses away. In way to remember this is afferent equals away.
What is neurons transmit signals across a?
the nucleus.
What function type are motor neurons?
motor neurons carry message from inter neurons and transmit it to different parts of the body.
Which structure in human transmit electrochemical messages?
Neurons
